Build Status Go Reference

Production-oriented Go phone parsing, validation, formatting, number matching, carrier/geocoding/time-zone lookup, and MCC/MNC enrichment. Its core tracks the Java reference implementation of Google's libphonenumber, through nyaruka/phonenumbers.

[!IMPORTANT] The aim of this project is strictly to be a port and match as closely as possible the functionality in libphonenumber. Please don't submit feature requests for functionality that doesn't exist in libphonenumber.

[!IMPORTANT] We use the metadata from libphonenumber so if you encounter unexpected parsing results, please first verify if the problem affects libphonenumber and report there if so. You can use their online demo to quickly check parsing results.

Version Numbers

As we don't want to bump our major semantic version number in step with the upstream library, we use independent version numbers than the Google libphonenumber repo. The release notes will mention what version of the metadata a release was built against.

Usage

import phone "github.com/oarkflow/phone"

// parse our phone number
num, err := phone.Parse("6502530000", "US")

// format it using national format
formattedNum := phone.Format(num, phone.NATIONAL)

// or use the enriched convenience API
verified := phone.Verify("+1 650 253 0000")

Updating Metadata

The buildmetadata command clones an upstream libphonenumber release and rebuilds the embedded metadata into the gzipped files under data/:

  • data/metadata.xml.gz - core territory metadata (number formats, validation rules, etc.)
  • data/shortnumber_metadata.xml.gz - short-number metadata
  • data/alternateformats_metadata.xml.gz - alternate format patterns used when matching
  • data/countrycode_to_region.xml.gz - maps a country code to its region(s)
  • data/prefix_to_carriers/*.gz - maps a phone number prefix to a carrier
  • data/prefix_to_geocodings/*.gz - maps a phone number prefix to a geographic area
  • data/prefix_to_timezone.xml.gz - maps a phone number prefix to a timezone

By default it resolves the latest upstream release tag, rebuilds data/, and records the release it used in the generated metadataversion.go (the exported MetadataVersion constant):

% go run ./cmd/buildmetadata

To rebuild from a specific release instead, pass the tag:

% go run ./cmd/buildmetadata v9.0.33

After syncing, run the tests and update SYNC.md — which records the upstream version the port is reconciled against and the deliberate divergences from upstream.

Overview

Port of metadata/source/* alternate-formats loading from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of AsYouTypeFormatter.java from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of tools/.../BuildMetadataFromXml.java from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of carrier/PhoneNumberToCarrierMapper.java from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Package phonenumbers is a Go port of Google's libphonenumber for parsing, formatting, and validating international phone numbers.

It tracks the Java implementation — libphonenumber's reference implementation, of which the C++ and JavaScript versions are themselves ports. As a result, type names, method names, and tests deliberately mirror their Java counterparts (for example PhoneNumberUtil and PhoneNumberUtilTest) to keep the port easy to verify against upstream. The aim is strictly to match libphonenumber's functionality rather than to add to it.

See SYNC.md for which upstream version each ported file is reconciled against.

Port of PhoneNumberUtil.java (enums) from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of NumberParseException.java + package errors from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of geocoder/geocoding/PhoneNumberOfflineGeocoder.java from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of metadata/source/* + MetadataLoader from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of PhoneNumberMatcher.java from google/libphonenumber. Methods are kept in upstream source order to ease syncing.

Port of PhoneNumberUtil.java from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Port of internal/prefixmapper/* (shared prefix lookup) from google/libphonenumber. Functions are kept in upstream source order to ease syncing.

Functions

func AllNumberGroupsAreExactlyPresent

func AllNumberGroupsAreExactlyPresent(
	number *PhoneNumber,
	normalizedCandidate string,
	formattedNumberGroups []string) bool

AllNumberGroupsAreExactlyPresent reports that the groups of digits in the candidate exactly match how the number would be formatted (the EXACT_GROUPING check).

func AllNumberGroupsRemainGrouped

func AllNumberGroupsRemainGrouped(
	number *PhoneNumber,
	normalizedCandidate string,
	formattedNumberGroups []string) bool

AllNumberGroupsRemainGrouped reports that the number groups found in the candidate are not broken up differently from how the number would be formatted (the STRICT_GROUPING check).

func BuildCountryCodeToRegionMap

func BuildCountryCodeToRegionMap(metadataCollection *PhoneMetadataCollection) map[int][]string

Build a mapping from a country calling code to the region codes which denote the country/region represented by that country code. In the case of multiple countries sharing a calling code, such as the NANPA countries, the one indicated with "isMainCountryForCode" in the metadata should be first.

func CanBeInternationallyDialled

func CanBeInternationallyDialled(number *PhoneNumber) bool

CanBeInternationallyDialled reports whether number may be dialled from outside its region. It does not validate the number first.

func CheckNumberGroupingIsValid

func CheckNumberGroupingIsValid(
	number *PhoneNumber,
	candidate string,
	checker func(number *PhoneNumber, normalizedCandidate string, expectedNumberGroups []string) bool) bool

CheckNumberGroupingIsValid checks the digit groups of candidate against the expected grouping for number using checker, falling back to any alternate formats for the number's country calling code.

func Clean

func Clean(phone []string, defaultRegion ...string) (VerifiedNumbers, UnverifiedNumbers)

func ConnectsToEmergencyNumber

func ConnectsToEmergencyNumber(number string, regionCode string) bool

Returns true if the given number, exactly as dialed, might be used to connect to an emergency service in the given region.

This method accepts a string, rather than a PhoneNumber, because it needs to distinguish cases such as "+1 911" and "911", where the former may not connect to an emergency service in all cases but the latter would. This method takes into account cases where the number might contain formatting, or might have additional digits appended (when it is okay to do that in the specified region).

number: the phone number to test regionCode: the region where the phone number is being dialed return: whether the number might be used to connect to an emergency service in the given region

func ContainsMoreThanOneSlashInNationalNumber

func ContainsMoreThanOneSlashInNationalNumber(number *PhoneNumber, candidate string) bool

ContainsMoreThanOneSlashInNationalNumber reports whether candidate contains more than one slash in the national-number portion (used to reject dates).

func ContainsOnlyValidXChars

func ContainsOnlyValidXChars(number *PhoneNumber, candidate string) bool

ContainsOnlyValidXChars reports whether every 'x'/'X' in candidate represents a carrier code or an extension sign (and not, say, a vanity-number letter).

func ConvertAlphaCharactersInNumber

func ConvertAlphaCharactersInNumber(number string) string

Converts all alpha characters in a number to their respective digits on a keypad, but retains existing formatting.

func CountryCodes

func CountryCodes() []string

CountryCodes returns a list of country codes, sorted by alpha

func CountryNames

func CountryNames() []string

CountryNames returns a list of country names, sorted by alpha

func Currency

func Currency(code string) string

Currency returns a countries currency. Note that it defaults to an empty string if country not found

func CurrencySymbol

func CurrencySymbol(code string) string

CurrencySymbol returns a countries currency symbol. Note that it defaults to an empty string if country not found

func FindNumbers

func FindNumbers(text, defaultRegion string) iter.Seq[*PhoneNumberMatch]

FindNumbers returns an iterator over all phone-number matches in text. It is a shortcut for FindNumbersWithLeniency with VALID leniency and no limit on the number of invalid candidates tried. defaultRegion is the region to assume for numbers not written in international format; pass "" or "ZZ" to only consider numbers with a leading plus.

Range over the result with for/range:

for m := range phonenumbers.FindNumbers(text, "US") {
	fmt.Println(m.RawString(), m.Start(), m.End())
}

func FindNumbersWithLeniency

func FindNumbersWithLeniency(text, defaultRegion string, leniency Leniency, maxTries int) iter.Seq[*PhoneNumberMatch]

FindNumbersWithLeniency returns an iterator over all phone-number matches in text at the given leniency. maxTries caps the number of invalid candidates tried before giving up, to bound degenerate inputs with many false positives (use math.MaxInt for no practical limit). Must be >= 0.

func Format

func Format(number *PhoneNumber, numberFormat PhoneNumberFormat) string

Formats a phone number in the specified format using default rules. Note that this does not promise to produce a phone number that the user can dial from where they are - although we do format in either 'national' or 'international' format depending on what the client asks for, we do not currently support a more abbreviated format, such as for users in the same "area" who could potentially dial the number without area code. Note that if the phone number has a country calling code of 0 or an otherwise invalid country calling code, we cannot work out which formatting rules to apply so we return the national significant number with no formatting applied.

func FormatByPattern

func FormatByPattern(number *PhoneNumber,
	numberFormat PhoneNumberFormat,
	userDefinedFormats []*NumberFormat) string

FormatByPattern formats a phone number in the specified format using client-defined formatting rules. Note that if the phone number has a country calling code of zero or an otherwise invalid country calling code, we cannot work out things like whether there should be a national prefix applied, or how to format extensions, so we return the national significant number with no formatting applied.

func FormatInOriginalFormat

func FormatInOriginalFormat(number *PhoneNumber, regionCallingFrom string) string

Formats a phone number using the original phone number format that the number is parsed from. The original format is embedded in the country_code_source field of the PhoneNumber object passed in. If such information is missing, the number will be formatted into the NATIONAL format by default. When the number contains a leading zero and this is unexpected for this country, or we don't have a formatting pattern for the number, the method returns the raw input when it is available.

Note this method guarantees no digit will be inserted, removed or modified as a result of formatting.

func FormatNationalNumberWithCarrierCode

func FormatNationalNumberWithCarrierCode(number *PhoneNumber, carrierCode string) string

Formats a phone number in national format for dialing using the carrier as specified in the carrierCode. The carrierCode will always be used regardless of whether the phone number already has a preferred domestic carrier code stored. If carrierCode contains an empty string, returns the number in national format without any carrier code.

func FormatNationalNumberWithPreferredCarrierCode

func FormatNationalNumberWithPreferredCarrierCode(
	number *PhoneNumber,
	fallbackCarrierCode string) string

Formats a phone number in national format for dialing using the carrier as specified in the preferredDomesticCarrierCode field of the PhoneNumber object passed in. If that is missing, use the fallbackCarrierCode passed in instead. If there is no preferredDomesticCarrierCode, and the fallbackCarrierCode contains an empty string, return the number in national format without any carrier code.

Use formatNationalNumberWithCarrierCode instead if the carrier code passed in should take precedence over the number's preferredDomesticCarrierCode when formatting.

func FormatNumberForMobileDialing

func FormatNumberForMobileDialing(
	number *PhoneNumber,
	regionCallingFrom string,
	withFormatting bool) string

Returns a number formatted in such a way that it can be dialed from a mobile phone in a specific region. If the number cannot be reached from the region (e.g. some countries block toll-free numbers from being called outside of the country), the method returns an empty string.

func FormatOutOfCountryCallingNumber

func FormatOutOfCountryCallingNumber(
	number *PhoneNumber,
	regionCallingFrom string) string

Formats a phone number for out-of-country dialing purposes. If no regionCallingFrom is supplied, we format the number in its INTERNATIONAL format. If the country calling code is the same as that of the region where the number is from, then NATIONAL formatting will be applied.

If the number itself has a country calling code of zero or an otherwise invalid country calling code, then we return the number with no formatting applied.

Note this function takes care of the case for calling inside of NANPA and between Russia and Kazakhstan (who share the same country calling code). In those cases, no international prefix is used. For regions which have multiple international prefixes, the number in its INTERNATIONAL format will be returned instead.

func FormatOutOfCountryKeepingAlphaChars

func FormatOutOfCountryKeepingAlphaChars(
	number *PhoneNumber,
	regionCallingFrom string) string

Formats a phone number for out-of-country dialing purposes.

Note that in this version, if the number was entered originally using alpha characters and this version of the number is stored in raw_input, this representation of the number will be used rather than the digit representation. Grouping information, as specified by characters such as "-" and " ", will be retained.

Caveats:

  • This will not produce good results if the country calling code is both present in the raw input _and_ is the start of the national number. This is not a problem in the regions which typically use alpha numbers.
  • This will also not produce good results if the raw input has any grouping information within the first three digits of the national number, and if the function needs to strip preceding digits/words in the raw input before these digits. Normally people group the first three digits together so this is not a huge problem - and will be fixed if it proves to be so.

func FormatWithBuf deprecated

func FormatWithBuf(number *PhoneNumber, numberFormat PhoneNumberFormat, formattedNumber *StringBuilder)

Same as Format(PhoneNumber, PhoneNumberFormat), but accepts a mutable StringBuilder as a parameter to decrease object creation when invoked many times.

Deprecated: use Format instead. This only exists to mirror Java's format(PhoneNumber, PhoneNumberFormat, StringBuilder) overload, and it leaks the internal StringBuilder type into the public API. The allocation it saves is negligible in practice, since formatting must prepend the country calling code, which forces the buffer to be rebuilt on every call anyway.

func GetCarrierForNumber

func GetCarrierForNumber(number *PhoneNumber, lang string) (string, error)

GetCarrierForNumber returns the carrier we believe the number belongs to. Note due to number porting this is only a guess, there is no guarantee to its accuracy.

func GetCarrierForValidNumber

func GetCarrierForValidNumber(number *PhoneNumber, lang string) (string, error)

GetCarrierForValidNumber performs carrier lookup without repeating number type validation. Callers must supply a valid mobile-capable number.

func GetCarrierWithPrefixForNumber

func GetCarrierWithPrefixForNumber(number *PhoneNumber, lang string) (string, int, error)

GetCarrierWithPrefixForNumber returns the carrier we believe the number belongs to, as well as its prefix. Note due to number porting this is only a guess, there is no guarantee to its accuracy.

func GetCountryCodeForRegion

func GetCountryCodeForRegion(regionCode string) int

Returns the country calling code for a specific region. For example, this would be 1 for the United States, and 64 for New Zealand.

func GetCountryMobileToken

func GetCountryMobileToken(countryCallingCode int) string

Returns the mobile token for the provided country calling code if it has one, otherwise returns an empty string. A mobile token is a number inserted before the area code when dialing a mobile number from that country from abroad.

func GetGeocodingForNumber

func GetGeocodingForNumber(number *PhoneNumber, lang string) (string, error)

GetGeocodingForNumber returns the location we think the number was first acquired in. This is just our best guess, there is no guarantee to its accuracy.

func GetLengthOfGeographicalAreaCode

func GetLengthOfGeographicalAreaCode(number *PhoneNumber) int

Gets the length of the geographical area code from the PhoneNumber object passed in, so that clients could use it to split a national significant number into geographical area code and subscriber number. It works in such a way that the resultant subscriber number should be diallable, at least on some devices. An example of how this could be used:

number, err := Parse("16502530000", "US");
// ... deal with err appropriately ...
nationalSignificantNumber := GetNationalSignificantNumber(number);
var areaCode, subscriberNumber;

int areaCodeLength = GetLengthOfGeographicalAreaCode(number);
if (areaCodeLength > 0) {
  areaCode = nationalSignificantNumber[0:areaCodeLength];
  subscriberNumber = nationalSignificantNumber[areaCodeLength:];
} else {
  areaCode = "";
  subscriberNumber = nationalSignificantNumber;
}

N.B.: area code is a very ambiguous concept, so the I18N team generally recommends against using it for most purposes, but recommends using the more general national_number instead. Read the following carefully before deciding to use this method:

  • geographical area codes change over time, and this method honors those changes; therefore, it doesn't guarantee the stability of the result it produces.
  • subscriber numbers may not be diallable from all devices (notably mobile devices, which typically requires the full national_number to be dialled in most regions).
  • most non-geographical numbers have no area codes, including numbers from non-geographical entities
  • some geographical numbers have no area codes.

func GetLengthOfNationalDestinationCode

func GetLengthOfNationalDestinationCode(number *PhoneNumber) int

Gets the length of the national destination code (NDC) from the PhoneNumber object passed in, so that clients could use it to split a national significant number into NDC and subscriber number. The NDC of a phone number is normally the first group of digit(s) right after the country calling code when the number is formatted in the international format, if there is a subscriber number part that follows. An example of how this could be used:

PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
PhoneNumber number = phoneUtil.parse("18002530000", "US");
String nationalSignificantNumber = phoneUtil.GetNationalSignificantNumber(number);
String nationalDestinationCode;
String subscriberNumber;

int nationalDestinationCodeLength =
    phoneUtil.GetLengthOfNationalDestinationCode(number);
if nationalDestinationCodeLength > 0 {
    nationalDestinationCode = nationalSignificantNumber.substring(0,
        nationalDestinationCodeLength);
    subscriberNumber = nationalSignificantNumber.substring(
        nationalDestinationCodeLength);
} else {
    nationalDestinationCode = "";
    subscriberNumber = nationalSignificantNumber;
}

Refer to the unittests to see the difference between this function and GetLengthOfGeographicalAreaCode().

func GetNationalSignificantNumber

func GetNationalSignificantNumber(number *PhoneNumber) string

Gets the national significant number of the a phone number. Note a national significant number doesn't contain a national prefix or any formatting.

func GetNddPrefixForRegion

func GetNddPrefixForRegion(regionCode string, stripNonDigits bool) string

Returns the national dialling prefix for a specific region. For example, this would be 1 for the United States, and 0 for New Zealand. Set stripNonDigits to true to strip symbols like "~" (which indicates a wait for a dialling tone) from the prefix returned. If no national prefix is present, we return null.

Warning: Do not use this method for do-your-own formatting - for some regions, the national dialling prefix is used only for certain types of numbers. Use the library's formatting functions to prefix the national prefix when required.

func GetRegionCodeForCountryCode

func GetRegionCodeForCountryCode(countryCallingCode int) string

Returns the region code that matches the specific country calling code. In the case of no region code being found, ZZ will be returned. In the case of multiple regions, the one designated in the metadata as the "main" region for this calling code will be returned. If the countryCallingCode entered is valid but doesn't match a specific region (such as in the case of non-geographical calling codes like 800) the value "001" will be returned (corresponding to the value for World in the UN M.49 schema).

func GetRegionCodeForNumber

func GetRegionCodeForNumber(number *PhoneNumber) string

Returns the region where a phone number is from. This could be used for geocoding at the region level.

func GetRegionCodesForCountryCode

func GetRegionCodesForCountryCode(countryCallingCode int) []string

Returns a list with the region codes that match the specific country calling code. For non-geographical country calling codes, the region code 001 is returned. Also, in the case of no region code being found, an empty list is returned.

func GetSafeCarrierDisplayNameForNumber

func GetSafeCarrierDisplayNameForNumber(phoneNumber *PhoneNumber, lang string) (string, error)

GetSafeCarrierDisplayNameForNumber Gets the name of the carrier for the given phone number only when it is 'safe' to display to users. A carrier name is considered safe if the number is valid and for a region that doesn't support mobile number portability .

func GetSupportedCallingCodes

func GetSupportedCallingCodes() map[int]bool

GetSupportedCallingCodes returns all country calling codes the library has metadata for, covering both non-geographical entities (global network calling codes) and those used for geographical entities. This could be used to populate a drop-down box of country calling codes for a phone-number widget, for instance.

func GetSupportedGlobalNetworkCallingCodes

func GetSupportedGlobalNetworkCallingCodes() map[int]bool

GetSupportedGlobalNetworkCallingCodes returns all global network calling codes the library has metadata for.

func GetSupportedRegions

func GetSupportedRegions() map[string]bool

GetSupportedRegions returns all regions the library has metadata for.

func GetSupportedTypesForNonGeoEntity

func GetSupportedTypesForNonGeoEntity(countryCallingCode int) map[PhoneNumberType]bool

GetSupportedTypesForNonGeoEntity returns the types for a country-code belonging to a non-geographical entity which the library has metadata for. Will not include FIXED_LINE_OR_MOBILE or UNKNOWN. No types are returned for country calling codes that do not map to a known non-geographical entity.

func GetSupportedTypesForRegion

func GetSupportedTypesForRegion(regionCode string) map[PhoneNumberType]bool

GetSupportedTypesForRegion returns the types for a given region which the library has metadata for. Will not include FIXED_LINE_OR_MOBILE or UNKNOWN. No types are returned for invalid or unknown region codes.

func GetTimeZonesForGeographicalNumber

func GetTimeZonesForGeographicalNumber(number *PhoneNumber) ([]string, error)

GetTimeZonesForGeographicalNumber returns time zones for a parsed geographical number.

func GetTimeZonesForNumber

func GetTimeZonesForNumber(number *PhoneNumber) ([]string, error)

GetTimeZonesForNumber is the upstream-compatible spelling of GetTimezonesForNumber.

func GetTimezonesForNumber

func GetTimezonesForNumber(number *PhoneNumber) ([]string, error)

GetTimezonesForNumber returns the names of timezones which we believe maps to the passed in number.

func GetTimezonesForPrefix

func GetTimezonesForPrefix(number string) ([]string, error)

GetTimezonesForPrefix returns a slice of Timezones corresponding to the number passed or error when it is impossible to convert the string to int The algorithm tries to match the timezones starting from the maximum number of phone number digits and decreasing until it finds one or reaches 0

func IsAlphaNumber

func IsAlphaNumber(number string) bool

Checks if the number is a valid vanity (alpha) number such as 800 MICROSOFT. A valid vanity number will start with at least 3 digits and will have three or more alpha characters. This does not do region-specific checks - to work out if this number is actually valid for a region, it should be parsed and methods such as IsPossibleNumberWithReason() and IsValidNumber() should be used.

func IsCarrierSpecific

func IsCarrierSpecific(number *PhoneNumber) bool

IsCarrierSpecific given a valid short number, determines whether it is carrier-specific (however, nothing is implied about its validity). Carrier-specific numbers may connect to a different end-point, or not connect at all, depending on the user's carrier. If it is important that the number is valid, then its validity must first be checked using IsValidShortNumber or IsValidShortNumberForRegion.

func IsCarrierSpecificForRegion

func IsCarrierSpecificForRegion(number *PhoneNumber, regionDialingFrom string) bool

IsCarrierSpecificForRegion given a valid short number, determines whether it is carrier-specific when dialed from the given region (however, nothing is implied about its validity). Returns false if the number doesn't match the region provided.

func IsEmergencyNumber

func IsEmergencyNumber(number string, regionCode string) bool

Returns true if the given number exactly matches an emergency service number in the given region.

This method takes into account cases where the number might contain formatting, but doesn't allow additional digits to be appended. Note that isEmergencyNumber(number, region) implies connectsToEmergencyNumber(number, region).

number: the phone number to test regionCode: the region where the phone number is being dialed return: whether the number exactly matches an emergency services number in the given region

func IsMobileNumberPortableRegion

func IsMobileNumberPortableRegion(regionCode string) bool

Returns true if the supplied region supports mobile number portability. Returns false for invalid, unknown or regions that don't support mobile number portability.

func IsNANPACountry

func IsNANPACountry(regionCode string) bool

Checks if this is a region under the North American Numbering Plan Administration (NANPA).

func IsNationalPrefixPresentIfRequired

func IsNationalPrefixPresentIfRequired(number *PhoneNumber) bool

IsNationalPrefixPresentIfRequired reports whether, if a national prefix is required to format number, it was present in the raw input.

func IsNumberGeographical

func IsNumberGeographical(number *PhoneNumber) bool

IsNumberGeographical reports whether number has a geographical association.

func IsNumberGeographicalForType

func IsNumberGeographicalForType(numberType PhoneNumberType, countryCallingCode int) bool

IsNumberGeographicalForType is the cheaper form of IsNumberGeographical when the caller already knows the number type and calling code.

func IsPossibleNumber

func IsPossibleNumber(number *PhoneNumber) bool

Convenience wrapper around IsPossibleNumberWithReason(). Instead of returning the reason for failure, this method returns a boolean value.

func IsPossibleNumberForType

func IsPossibleNumberForType(number *PhoneNumber, numberType PhoneNumberType) bool

IsPossibleNumberForType returns true if the number is a possible number of the given type (a more lenient check than IsValidNumberForRegion).

func IsPossibleNumberFromRegion

func IsPossibleNumberFromRegion(number, regionDialingFrom string) bool

IsPossibleNumberFromRegion parses number as dialled from regionDialingFrom and reports whether its length is possible. It is intentionally more lenient than IsValidNumber.

func IsPossibleShortNumber

func IsPossibleShortNumber(number *PhoneNumber) bool

Check whether a short number is a possible number. If a country calling code is shared by multiple regions, this returns true if it's possible in any of them. This provides a more lenient check than #isValidShortNumber. See IsPossibleShortNumberForRegion(PhoneNumber, string) for details.

func IsPossibleShortNumberForRegion

func IsPossibleShortNumberForRegion(number *PhoneNumber, regionDialingFrom string) bool

Check whether a short number is a possible number when dialed from the given region. This provides a more lenient check than IsValidShortNumberForRegion.

func IsSmsServiceForRegion

func IsSmsServiceForRegion(number *PhoneNumber, regionDialingFrom string) bool

IsSmsServiceForRegion given a valid short number, determines whether it is an SMS service (however, nothing is implied about its validity). An SMS service is where the primary or only intended usage is to receive and/or send text messages (SMSs). This includes MMS as MMS numbers downgrade to SMS if the other party isn't MMS-capable. Returns false if the number doesn't match the region provided.

func IsValidNumber

func IsValidNumber(number *PhoneNumber) bool

Tests whether a phone number matches a valid pattern. Note this doesn't verify the number is actually in use, which is impossible to tell by just looking at a number itself.

func IsValidNumberForRegion

func IsValidNumberForRegion(number *PhoneNumber, regionCode string) bool

Tests whether a phone number is valid for a certain region. Note this doesn't verify the number is actually in use, which is impossible to tell by just looking at a number itself. If the country calling code is not the same as the country calling code for the region, this immediately exits with false. After this, the specific number pattern rules for the region are examined. This is useful for determining for example whether a particular number is valid for Canada, rather than just a valid NANPA number. Warning: In most cases, you want to use IsValidNumber() instead. For example, this method will mark numbers from British Crown dependencies such as the Isle of Man as invalid for the region "GB" (United Kingdom), since it has its own region code, "IM", which may be undesirable.

func IsValidShortNumber

func IsValidShortNumber(number *PhoneNumber) bool

Tests whether a short number matches a valid pattern. If a country calling code is shared by multiple regions, this returns true if it's valid in any of them. Note that this doesn't verify the number is actually in use, which is impossible to tell by just looking at the number itself. See IsValidShortNumberForRegion(PhoneNumber, String) for details.

func IsValidShortNumberForRegion

func IsValidShortNumberForRegion(number *PhoneNumber, regionDialingFrom string) bool

Tests whether a short number matches a valid pattern in a region. Note that this doesn't verify the number is actually in use, which is impossible to tell by just looking at the number itself.

func LoadNetworks

func LoadNetworks() error

func MatchNationalNumber

func MatchNationalNumber(number string, numberDesc *PhoneNumberDesc, allowPrefixMatch bool) bool

MatchNationalNumber reports whether the given national number (a string of decimal digits) matches the national number pattern in numberDesc.

func MaybeSeparateExtensionFromPhone

func MaybeSeparateExtensionFromPhone(rawPhone string) (phoneNumber string, extension string)

MaybeSeparateExtensionFromPhone will extract any extension (as in, the part of the number dialled after the call is connected, usually indicated with extn, ext, x or similar) from the end of the number and returns it along with the proceeding phone number. The phone number will maintain its original formatting including alpha characters.

func Name

func Name(code string) string

Name returns a countries name. Note that it defaults to an empty string if country not found

func NormalizeDiallableCharsOnly

func NormalizeDiallableCharsOnly(number string) string

NormalizeDiallableCharsOnly strips characters that cannot be dialled on a phone keypad, including non-ASCII digits.

func NormalizeDigitsOnly

func NormalizeDigitsOnly(number string) string

Normalizes a string of characters representing a phone number. This converts wide-ascii and arabic-indic numerals to European numerals, and strips punctuation and alpha characters.

func ParseAndKeepRawInputToNumber

func ParseAndKeepRawInputToNumber(
	numberToParse, defaultRegion string,
	phoneNumber *PhoneNumber) error

Same as ParseAndKeepRawInput(String, String), but accepts a mutable PhoneNumber as a parameter to decrease object creation when invoked many times.

func ParseToNumber

func ParseToNumber(numberToParse, defaultRegion string, phoneNumber *PhoneNumber) error

Same as Parse(string, string), but accepts mutable PhoneNumber as a parameter to decrease object creation when invoked many times.

func Phone

func Phone(code string) string

Phone returns a countries phone ext. Note that it defaults to an empty string if country not found

func TruncateTooLongNumber

func TruncateTooLongNumber(number *PhoneNumber) bool

Attempts to extract a valid number from a phone number that is too long to be valid, and resets the PhoneNumber object passed in to that valid version. If no valid number could be extracted, the PhoneNumber object passed in will not be modified.

func Worker

func Worker(data map[string]string) bool

Types

type AnalyzeCarrierResult

type AnalyzeCarrierResult struct {
	CarrierName string `json:"carrier_name,omitempty"`
	CarrierCode string `json:"carrier_code,omitempty"`
	CountryCode string `json:"country,omitempty"`
	PhoneType   string `json:"phone_type,omitempty"`
	PhoneCount  int    `json:"phone_count"`

	PhoneCount  int    `json:"phone_count"`
}

type AsYouTypeFormatter

type AsYouTypeFormatter struct {
	// contains filtered or unexported fields
}

AsYouTypeFormatter formats phone numbers as they are entered. It is a port of libphonenumber's AsYouTypeFormatter (Java reference implementation).

An AsYouTypeFormatter is obtained from GetAsYouTypeFormatter. After that, digits can be added by calling InputDigit on the instance, and the partially formatted phone number is returned each time a digit is added. Clear can be called before formatting a new number.

See AsYouTypeFormatter's tests for more details on how the formatter is to be used.

func GetAsYouTypeFormatter

func GetAsYouTypeFormatter(regionCode string) *AsYouTypeFormatter

GetAsYouTypeFormatter returns an AsYouTypeFormatter for the specific region.

func (*AsYouTypeFormatter) Clear

func (aytf *AsYouTypeFormatter) Clear()

Clear clears the internal state of the formatter, so it can be reused.

func (*AsYouTypeFormatter) GetRememberedPosition

func (aytf *AsYouTypeFormatter) GetRememberedPosition() int

GetRememberedPosition returns the current position in the partially formatted phone number of the character which was previously passed in as the parameter of InputDigitAndRememberPosition.

func (*AsYouTypeFormatter) InputDigit

func (aytf *AsYouTypeFormatter) InputDigit(nextChar rune) string

InputDigit formats a phone number on-the-fly as each digit is entered.

nextChar is the most recently entered digit of a phone number. Formatting characters are allowed, but as soon as they are encountered this method formats the number as entered and not "as you type" anymore. Full width digits and Arabic-indic digits are allowed, and will be shown as they are. It returns the partially formatted phone number.

func (*AsYouTypeFormatter) InputDigitAndRememberPosition

func (aytf *AsYouTypeFormatter) InputDigitAndRememberPosition(nextChar rune) string

InputDigitAndRememberPosition is the same as InputDigit, but remembers the position where nextChar is inserted, so that it can be retrieved later using GetRememberedPosition. The remembered position will be automatically adjusted if additional formatting characters are later inserted/removed in front of nextChar.

func IsNumberMatch

func IsNumberMatch(firstNumber, secondNumber string) MatchType

Takes two phone numbers as strings and compares them for equality. This is a convenience wrapper for IsNumberMatch(PhoneNumber, PhoneNumber). No default region is known.

func IsNumberMatchWithNumbers

func IsNumberMatchWithNumbers(firstNumberIn, secondNumberIn *PhoneNumber) MatchType

Takes two phone numbers and compares them for equality.

Returns EXACT_MATCH if the country_code, NSN, presence of a leading zero for Italian numbers and any extension present are the same. Returns NSN_MATCH if either or both has no region specified, and the NSNs and extensions are the same. Returns SHORT_NSN_MATCH if either or both has no region specified, or the region specified is the same, and one NSN could be a shorter version of the other number. This includes the case where one has an extension specified, and the other does not. Returns NO_MATCH otherwise. For example, the numbers +1 345 657 1234 and 657 1234 are a SHORT_NSN_MATCH. The numbers +1 345 657 1234 and 345 657 are a NO_MATCH.

Gets a valid number for the specified region and number type.

func GetInvalidExampleNumber

func GetInvalidExampleNumber(regionCode string) *PhoneNumber

GetInvalidExampleNumber returns an invalid number for the specified region. This is useful for unit-testing purposes, where you want to test what happens with an invalid number. Returns nil when an unsupported region or the region 001 (Earth) is passed in.

func Parse

func Parse(numberToParse, defaultRegion string) (*PhoneNumber, error)

Parses a string and returns it in proto buffer format. This method will throw a NumberParseException if the number is not considered to be a possible number. Note that validation of whether the number is actually a valid number for a particular region is not performed. This can be done separately with IsValidNumber().

func ParseAndKeepRawInput

func ParseAndKeepRawInput(
	numberToParse, defaultRegion string) (*PhoneNumber, error)

Parses a string and returns it in proto buffer format. This method differs from Parse() in that it always populates the raw_input field of the protocol buffer with numberToParse as well as the country_code_source field.

type PhoneNumberMatch

type PhoneNumberMatch struct {

PhoneNumberMatch is the immutable match of a phone number within a piece of text. Matches may be found using FindNumbers.

A match consists of the phone number (Number) as well as the start and end byte offsets of the corresponding substring of the searched text. Use RawString to obtain the matched substring. Note that, unlike upstream's Java (which uses UTF-16 char offsets), Start and End are byte offsets into the searched string, so text[match.Start():match.End()] == match.RawString().

func (*PhoneNumberMatch) End

func (m *PhoneNumberMatch) End() int

End returns the exclusive end byte offset of the matched phone number within the searched text.

func (*PhoneNumberMatch) Number

func (m *PhoneNumberMatch) Number() *PhoneNumber

Number returns the phone number matched by the receiver.

func (*PhoneNumberMatch) RawString

func (m *PhoneNumberMatch) RawString() string

RawString returns the raw substring matched as a phone number in the searched text.

Cost categories of short numbers. Note these are suffixed with _COST to avoid clashing with the PhoneNumberType constants TOLL_FREE and PREMIUM_RATE.

func GetExpectedCost

func GetExpectedCost(number *PhoneNumber) ShortNumberCost

GetExpectedCost gets the expected cost category of a short number (however, nothing is implied about its validity). If the country calling code is unique to a region, this method behaves exactly the same as GetExpectedCostForRegion. However, if the country calling code is shared by multiple regions, then it returns the highest cost in the sequence PREMIUM_RATE, UNKNOWN_COST, STANDARD_RATE, TOLL_FREE. The reason for the position of UNKNOWN_COST in this order is that if a number is UNKNOWN_COST in one region but STANDARD_RATE or TOLL_FREE in another, its expected cost cannot be estimated as one of the latter since it might be a PREMIUM_RATE number.

Note: If the region from which the number is dialed is known, it is highly preferable to call GetExpectedCostForRegion instead.

func GetExpectedCostForRegion

func GetExpectedCostForRegion(number *PhoneNumber, regionDialingFrom string) ShortNumberCost

GetExpectedCostForRegion gets the expected cost category of a short number when dialed from a region (however, nothing is implied about its validity). If it is important that the number is valid, then its validity must first be checked using IsValidShortNumberForRegion. Note that emergency numbers are always considered toll-free. Returns UNKNOWN_COST if the number does not match a cost category. Note that an invalid number may match any cost category.

type StringBuilder

type StringBuilder struct {
	// contains filtered or unexported fields
}

StringBuilder is a minimal, mutable string buffer that mirrors the parts of java.lang.StringBuilder the libphonenumber port relies on — chiefly the ability to insert at an arbitrary index, which neither strings.Builder nor bytes.Buffer provide. It is backed by a plain []byte and leans on the standard library (slices.Insert, utf8.AppendRune) for the heavy lifting.

func NewStringBuilder

func NewStringBuilder(buf []byte) *StringBuilder

NewStringBuilder creates a StringBuilder using buf as its initial contents.

func NewStringBuilderString

func NewStringBuilderString(s string) *StringBuilder

NewStringBuilderString creates a StringBuilder using s as its initial contents.

func (*StringBuilder) ByteAt

func (b *StringBuilder) ByteAt(i int) (byte, error)

ByteAt returns the byte at index i, or ErrInvalidIndex if i is out of range.

func (*StringBuilder) Bytes

func (b *StringBuilder) Bytes() []byte

Bytes returns the underlying contents. The slice is valid until the next mutating call; callers that retain it should copy.

func (*StringBuilder) Insert

func (b *StringBuilder) Insert(i int, p []byte) (int, error)

Insert inserts p at index i, growing the buffer as needed. It returns ErrInvalidIndex if i is negative or greater than the buffer length.

func (*StringBuilder) InsertString

func (b *StringBuilder) InsertString(i int, s string) (int, error)

InsertString inserts s at index i, growing the buffer as needed. It returns ErrInvalidIndex if i is negative or greater than the buffer length.

func (*StringBuilder) Len

func (b *StringBuilder) Len() int

Len returns the number of bytes in the buffer.

func (*StringBuilder) Reset

func (b *StringBuilder) Reset()

Reset empties the buffer while retaining its capacity.

func (*StringBuilder) ResetWith

func (b *StringBuilder) ResetWith(buf []byte) (int, error)

ResetWith replaces the buffer's contents with buf.

func (*StringBuilder) ResetWithString

func (b *StringBuilder) ResetWithString(s string) (int, error)

ResetWithString replaces the buffer's contents with s.

func (*StringBuilder) String

func (b *StringBuilder) String() string

String returns the contents as a string. A nil receiver returns "<nil>", which is handy when debugging.

func (*StringBuilder) Write

func (b *StringBuilder) Write(p []byte) (int, error)

Write appends p to the buffer. The error is always nil; it exists to satisfy io.Writer.

func (*StringBuilder) WriteByte

func (b *StringBuilder) WriteByte(c byte) error

WriteByte appends c to the buffer. The error is always nil; it exists to satisfy io.ByteWriter.

func (*StringBuilder) WriteRune

func (b *StringBuilder) WriteRune(r rune) (int, error)

WriteRune appends the UTF-8 encoding of r to the buffer and returns the number of bytes written. The error is always nil.

func (*StringBuilder) WriteString

func (b *StringBuilder) WriteString(s string) (int, error)

WriteString appends s to the buffer. The error is always nil.

func IsPossibleNumberForTypeWithReason(number *PhoneNumber, numberType PhoneNumberType) ValidationResult

IsPossibleNumberForTypeWithReason checks whether a phone number is a possible number of a particular type. For most number types, this is the same result as IsPossibleNumberWithReason. See that method for details.

func IsPossibleNumberWithReason

func IsPossibleNumberWithReason(number *PhoneNumber) ValidationResult

Check whether a phone number is a possible number. It provides a more lenient check than IsValidNumber() in the following sense:

  • It only checks the length of phone numbers. In particular, it doesn't check starting digits of the number.
  • It doesn't attempt to figure out the type of the number, but uses general rules which applies to all types of phone numbers in a region. Therefore, it is much faster than isValidNumber.
  • For fixed line numbers, many regions have the concept of area code, which together with subscriber number constitute the national significant number. It is sometimes okay to dial the subscriber number only when dialing in the same area. This function will return true if the subscriber-number-only version is passed in. On the other hand, because isValidNumber validates using information on both starting digits (for fixed line numbers, that would most likely be area codes) and length (obviously includes the length of area codes for fixed line numbers), it will return false for the subscriber-number-only version.
