phonenumbers Build Status

golang port of Google's libphonenumber, forked from libphonenumber from ttacon

This will ultimately be a rewrite of ttacon's library, but for now mostly cleans up a few things, fixes some bugs and adds the buildmetadata cmd to allow for rebuilding the metadata protocol buffers, country code to region maps and timezone prefix maps.

This library is used daily in production for parsing and validation of numbers across the world, so is well maintained.

Usage

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

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

Rebuilding Metadata and Maps

The buildmetadata command will fetch the latest XML file from the official Google repo and rebuild the go source files containing all the territory metadata, timezone and region maps. It will rebuild the following files:

metadata_bin.go - contains the protocol buffer definitions for all the various formats across countries etc..

countrycode_to_region.go - contains a map built from the metadata to ease looking up possible regions for a country code

prefix_to_timezone.go - contains a map built from the timezone file within the Google repo mapping number prefixes to possible timezones

% go get github.com/nyaruka/phonenumbers
% go install github.com/nyaruka/phonenumbers/cmd/buildmetadata

Functions

func AllNumberGroupsAreExactlyPresent 

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

func AllNumberGroupsRemainGrouped 

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

func BuildCountryCodeToRegionMap 

func BuildCountryCodeToRegionMap(metadataCollection *PhoneMetadataCollection) map[int32][]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 CheckNumberGroupingIsValid 

func CheckNumberGroupingIsValid(
	number *PhoneNumber,
	candidate string,
	fn func(*PhoneNumber, string, []string) bool) bool

func ContainsMoreThanOneSlashInNationalNumber 

func ContainsMoreThanOneSlashInNationalNumber(
	number *PhoneNumber,
	candidate string) bool

func ContainsOnlyValidXChars 

func ContainsOnlyValidXChars(number *PhoneNumber, candidate string) bool

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 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

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 

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

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

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 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 GetSupportedGlobalNetworkCallingCodes 

func GetSupportedGlobalNetworkCallingCodes() map[int]struct{}

Convenience method to get a list of what global network calling codes the library has metadata for.

func GetSupportedRegions 

func GetSupportedRegions() map[string]struct{}

Convenience method to get a list of what regions the library has metadata for.

func GetTimezonesForPrefix 

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

Returns a slice of Timezones corresponding to the number passed or error when it is impossible to convert the string to int The algorythm 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 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

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 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 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 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.

Types

type Builder 

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

A Buffer is a variable-sized buffer of bytes with Read and Write methods. The zero value for Buffer is an empty buffer ready to use.

func NewBuilder 

func NewBuilder(buf []byte) *Builder

NewBuilder creates and initializes a new Buffer using buf as its initial contents. It is intended to prepare a Buffer to read existing data. It can also be used to size the internal buffer for writing. To do that, buf should have the desired capacity but a length of zero.

In most cases, new(Buffer) (or just declaring a Buffer variable) is sufficient to initialize a Buffer.

func NewBuilderString 

func NewBuilderString(s string) *Builder

NewBuilderString creates and initializes a new Buffer using string s as its initial contents. It is intended to prepare a buffer to read an existing string.

In most cases, new(Buffer) (or just declaring a Buffer variable) is sufficient to initialize a Buffer.

func (*Builder) ByteAt 

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

ByteAt returns the byte at the given index. It returns ErrInvalidIndex if the given index is outside the buffer's length. There is no RuneAt currently, for I'm unsure what the desired behaviour should be (read rune by rune until we get to the ith rune, read the rune starting at i).

func (*Builder) Bytes 

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

Bytes returns a slice of the contents of the unread portion of the buffer; len(b.Bytes()) == b.Len(). If the caller changes the contents of the returned slice, the contents of the buffer will change provided there are no intervening method calls on the Buffer.

func (*Builder) Grow 

func (b *Builder) Grow(n int)

Grow grows the buffer's capacity, if necessary, to guarantee space for another n bytes. After Grow(n), at least n bytes can be written to the buffer without another allocation. If n is negative, Grow will panic. If the buffer can't grow it will panic with ErrTooLarge.

func (*Builder) Insert 

func (b *Builder) Insert(i int, p []byte) (n int, err error)

Insert inserts the buffer at the desired position, growing the buffer as necessary. If i is less than zero, or greater than len(p), an error is returned.

func (*Builder) InsertString 

func (b *Builder) InsertString(i int, p string) (n int, err error)

InsertString inserts the string at the desired position, growing the buffer as necessary. If i is less than zero, or greater than len(p), an error is returned.

func (*Builder) Len 

func (b *Builder) Len() int

Len returns the number of bytes of the unread portion of the buffer; b.Len() == len(b.Bytes()).

func (*Builder) Next 

func (b *Builder) Next(n int) []byte

Next returns a slice containing the next n bytes from the buffer, advancing the buffer as if the bytes had been returned by Read. If there are fewer than n bytes in the buffer, Next returns the entire buffer. The slice is only valid until the next call to a read or write method.

func (*Builder) Read 

func (b *Builder) Read(p []byte) (n int, err error)

Read reads the next len(p) bytes from the buffer or until the buffer is drained. The return value n is the number of bytes read. If the buffer has no data to return, err is io.EOF (unless len(p) is zero); otherwise it is nil.

func (*Builder) ReadByte 

func (b *Builder) ReadByte() (c byte, err error)

ReadByte reads and returns the next byte from the buffer. If no byte is available, it returns error io.EOF.

func (*Builder) ReadBytes 

func (b *Builder) ReadBytes(delim byte) (line []byte, err error)

ReadBytes reads until the first occurrence of delim in the input, returning a slice containing the data up to and including the delimiter. If ReadBytes encounters an error before finding a delimiter, it returns the data read before the error and the error itself (often io.EOF). ReadBytes returns err != nil if and only if the returned data does not end in delim.

func (*Builder) ReadFrom 

func (b *Builder) ReadFrom(r io.Reader) (n int64, err error)

ReadFrom reads data from r until EOF and appends it to the buffer, growing the buffer as needed. The return value n is the number of bytes read. Any error except io.EOF encountered during the read is also returned. If the buffer becomes too large, ReadFrom will panic with ErrTooLarge.

func (*Builder) ReadRune 

func (b *Builder) ReadRune() (r rune, size int, err error)

ReadRune reads and returns the next UTF-8-encoded Unicode code point from the buffer. If no bytes are available, the error returned is io.EOF. If the bytes are an erroneous UTF-8 encoding, it consumes one byte and returns U+FFFD, 1.

func (*Builder) ReadString 

func (b *Builder) ReadString(delim byte) (line string, err error)

ReadString reads until the first occurrence of delim in the input, returning a string containing the data up to and including the delimiter. If ReadString encounters an error before finding a delimiter, it returns the data read before the error and the error itself (often io.EOF). ReadString returns err != nil if and only if the returned data does not end in delim.

func (*Builder) Reset 

func (b *Builder) Reset()

Reset resets the buffer so it has no content. b.Reset() is the same as b.Truncate(0).

func (*Builder) ResetWith 

func (b *Builder) ResetWith(buf []byte) (n int, err error)

func (*Builder) ResetWithString 

func (b *Builder) ResetWithString(s string) (n int, err error)

func (*Builder) String 

func (b *Builder) String() string

String returns the contents of the unread portion of the buffer as a string. If the Buffer is a nil pointer, it returns "<nil>".

func (*Builder) Truncate 

func (b *Builder) Truncate(n int)

Truncate discards all but the first n unread bytes from the buffer. It panics if n is negative or greater than the length of the buffer.

func (*Builder) UnreadByte 

func (b *Builder) UnreadByte() error

UnreadByte unreads the last byte returned by the most recent read operation. If write has happened since the last read, UnreadByte returns an error.

func (*Builder) UnreadRune 

func (b *Builder) UnreadRune() error

UnreadRune unreads the last rune returned by ReadRune. If the most recent read or write operation on the buffer was not a ReadRune, UnreadRune returns an error. (In this regard it is stricter than UnreadByte, which will unread the last byte from any read operation.)

func (*Builder) Write 

func (b *Builder) Write(p []byte) (n int, err error)

Write appends the contents of p to the buffer, growing the buffer as needed. The return value n is the length of p; err is always nil. If the buffer becomes too large, Write will panic with ErrTooLarge.

func (*Builder) WriteByte 

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

WriteByte appends the byte c to the buffer, growing the buffer as needed. The returned error is always nil, but is included to match bufio.Writer's WriteByte. If the buffer becomes too large, WriteByte will panic with ErrTooLarge.

func (*Builder) WriteRune 

func (b *Builder) WriteRune(r rune) (n int, err error)

WriteRune appends the UTF-8 encoding of Unicode code point r to the buffer, returning its length and an error, which is always nil but is included to match bufio.Writer's WriteRune. The buffer is grown as needed; if it becomes too large, WriteRune will panic with ErrTooLarge.

func (*Builder) WriteString 

func (b *Builder) WriteString(s string) (n int, err error)

WriteString appends the contents of s to the buffer, growing the buffer as needed. The return value n is the length of s; err is always nil. If the buffer becomes too large, WriteString will panic with ErrTooLarge.

func (*Builder) WriteTo 

func (b *Builder) WriteTo(w io.Writer) (n int64, err error)

WriteTo writes data to w until the buffer is drained or an error occurs. The return value n is the number of bytes written; it always fits into an int, but it is int64 to match the io.WriterTo interface. Any error encountered during the write is also returned.

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.

type NumberFormat 

type NumberFormat struct {
	// pattern is a regex that is used to match the national (significant)
	// number. For example, the pattern "(20)(\d{4})(\d{4})" will match number

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.
