• required string pattern = 1

  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 "2070313000", which is the national (significant) number for Google London. Note the presence of the parentheses, which are capturing groups what specifies the grouping of numbers.

• required string format = 2

  format specifies how the national (significant) number matched by pattern should be formatted. Using the same example as above, format could contain "$1 $2 $3", meaning that the number should be formatted as "20 7031 3000". Each $x are replaced by the numbers captured by group x in the regex specified by pattern.

• repeated string leading_digits_pattern = 3

  This field is a regex that is used to match a certain number of digits at the beginning of the national (significant) number. When the match is successful, the accompanying pattern and format should be used to format this number. For example, if leading_digits="[1-3]|44", then all the national numbers starting with 1, 2, 3 or 44 should be formatted using the accompanying pattern and format. The first leadingDigitsPattern matches up to the first three digits of the national (significant) number; the next one matches the first four digits, then the first five and so on, until the leadingDigitsPattern can uniquely identify one pattern and format to be used to format the number. In the case when only one formatting pattern exists, no leading_digits_pattern is needed.

• optional string national_prefix_formatting_rule = 4

  This field specifies how the national prefix ($NP) together with the first group ($FG) in the national significant number should be formatted in the NATIONAL format when a national prefix exists for a certain country. For example, when this field contains "($NP$FG)", a number from Beijing, China (whose $NP = 0), which would by default be formatted without national prefix as 10 1234 5678 in NATIONAL format, will instead be formatted as (010) 1234 5678; to format it as (0)10 1234 5678, the field would contain "($NP)$FG". Note $FG should always be present in this field, but $NP can be omitted. For example, having "$FG" could indicate the number should be formatted in NATIONAL format without the national prefix. This is commonly used to override the rule specified for the territory in the XML file. When this field is missing, a number will be formatted without national prefix in NATIONAL format. This field does not affect how a number is formatted in other formats, such as INTERNATIONAL.

• optional bool national_prefix_optional_when_formatting = 6

  This field specifies whether the $NP can be omitted when formatting a number in national format, even though it usually wouldn't be. For example, a UK number would be formatted by our library as 020 XXXX XXXX. If we have commonly seen this number written by people without the leading 0, for example as (20) XXXX XXXX, this field would be set to true. This will be inherited from the value set for the territory in the XML file, unless a national_prefix_formatting_rule is defined specifically for this NumberFormat.

• optional string domestic_carrier_code_formatting_rule = 5

  This field specifies how any carrier code ($CC) together with the first group ($FG) in the national significant number should be formatted when formatWithCarrierCode is called, if carrier codes are used for a certain country.

Used in: PhoneMetadataCollection

• optional PhoneNumberDesc general_desc = 1

  The general_desc contains information which is a superset of descriptions for all types of phone numbers. If any element is missing in the description of a specific type in the XML file, the element will inherit from its counterpart in the general_desc. Every locale is assumed to have fixed line and mobile numbers - if these types are missing in the PhoneNumberMetadata XML file, they will inherit all fields from the general_desc. For all other types that are generally relevant to normal phone numbers, if the whole type is missing in the PhoneNumberMetadata XML file, it will be given a national_number_pattern of "NA" and a possible_number_pattern of "NA".

• optional PhoneNumberDesc fixed_line = 2

• optional PhoneNumberDesc mobile = 3

• optional PhoneNumberDesc toll_free = 4

• optional PhoneNumberDesc premium_rate = 5

• optional PhoneNumberDesc shared_cost = 6

• optional PhoneNumberDesc personal_number = 7

• optional PhoneNumberDesc voip = 8

• optional PhoneNumberDesc pager = 21

• optional PhoneNumberDesc uan = 25

• optional PhoneNumberDesc emergency = 27

• optional PhoneNumberDesc voicemail = 28

• optional PhoneNumberDesc short_code = 29

• optional PhoneNumberDesc standard_rate = 30

• optional PhoneNumberDesc carrier_specific = 31

• optional PhoneNumberDesc no_international_dialling = 24

  The rules here distinguish the numbers that are only able to be dialled nationally.

• required string id = 9

  The ISO 3166-1 alpha-2 representation of a country/region, with the exception of "country calling codes" used for non-geographical entities, such as Universal International Toll Free Number (+800). These are all given the ID "001", since this is the numeric region code for the world according to UN M.49: http://en.wikipedia.org/wiki/UN_M.49

• optional int32 country_code = 10

  The country calling code that one would dial from overseas when trying to dial a phone number in this country. For example, this would be "64" for New Zealand.

• optional string international_prefix = 11

  The international_prefix of country A is the number that needs to be dialled from country A to another country (country B). This is followed by the country code for country B. Note that some countries may have more than one international prefix, and for those cases, a regular expression matching the international prefixes will be stored in this field.

• optional string preferred_international_prefix = 17

  If more than one international prefix is present, a preferred prefix can be specified here for out-of-country formatting purposes. If this field is not present, and multiple international prefixes are present, then "+" will be used instead.

• optional string national_prefix = 12

  The national prefix of country A is the number that needs to be dialled before the national significant number when dialling internally. This would not be dialled when dialling internationally. For example, in New Zealand, the number that would be locally dialled as 09 345 3456 would be dialled from overseas as +64 9 345 3456. In this case, 0 is the national prefix.

• optional string preferred_extn_prefix = 13

  The preferred prefix when specifying an extension in this country. This is used for formatting only, and if this is not specified, a suitable default should be used instead. For example, if you wanted extensions to be formatted in the following way: 1 (365) 345 445 ext. 2345 " ext. " should be the preferred extension prefix.

• optional string national_prefix_for_parsing = 15

  This field is used for cases where the national prefix of a country contains a carrier selection code, and is written in the form of a regular expression. For example, to dial the number 2222-2222 in Fortaleza, Brazil (area code 85) using the long distance carrier Oi (selection code 31), one would dial 0 31 85 2222 2222. Assuming the only other possible carrier selection code is 32, the field will contain "03[12]". When it is missing from the XML file, this field inherits the value of national_prefix, if that is present.

• optional string national_prefix_transform_rule = 16

  This field is only populated and used under very rare situations. For example, mobile numbers in Argentina are written in two completely different ways when dialed in-country and out-of-country (e.g. 0343 15 555 1212 is exactly the same number as +54 9 343 555 1212). This field is used together with national_prefix_for_parsing to transform the number into a particular representation for storing in the phonenumber proto buffer in those rare cases.

• optional bool same_mobile_and_fixed_line_pattern = 18

  Specifies whether the mobile and fixed-line patterns are the same or not. This is used to speed up determining phone number type in countries where these two types of phone numbers can never be distinguished.

• repeated NumberFormat number_format = 19

  Note that the number format here is used for formatting only, not parsing. Hence all the varied ways a user *may* write a number need not be recorded - just the ideal way we would like to format it for them. When this element is absent, the national significant number will be formatted as a whole without any formatting applied.

• repeated NumberFormat intl_number_format = 20

  This field is populated only when the national significant number is formatted differently when it forms part of the INTERNATIONAL format and NATIONAL format. A case in point is mobile numbers in Argentina: The number, which would be written in INTERNATIONAL format as +54 9 343 555 1212, will be written as 0343 15 555 1212 for NATIONAL format. In this case, the prefix 9 is inserted when dialling from overseas, but otherwise the prefix 0 and the carrier selection code 15 (inserted after the area code of 343) is used. Note: this field is populated by setting a value for <intlFormat> inside the <numberFormat> tag in the XML file. If <intlFormat> is not set then it defaults to the same value as the <format> tag. Examples: To set the <intlFormat> to a different value than the <format>: <numberFormat pattern=....> <format>$1 $2 $3</format> <intlFormat>$1-$2-$3</intlFormat> </numberFormat> To have a format only used for national formatting, set <intlFormat> to "NA": <numberFormat pattern=....> <format>$1 $2 $3</format> <intlFormat>NA</intlFormat> </numberFormat>

• optional bool main_country_for_code = 22

  This field is set when this country is considered to be the main country for a calling code. It may not be set by more than one country with the same calling code, and it should not be set by countries with a unique calling code. This can be used to indicate that "GB" is the main country for the calling code "44" for example, rather than Jersey or the Isle of Man.

• optional string leading_digits = 23

  This field is populated only for countries or regions that share a country calling code. If a number matches this pattern, it could belong to this region. This is not intended as a replacement for IsValidForRegion, and does not mean the number must come from this region (for example, 800 numbers are valid for all NANPA countries.) This field should be a regular expression of the expected prefix match.

• optional bool leading_zero_possible = 26

  The leading zero in a phone number is meaningful in some countries (e.g. Italy). This means they cannot be dropped from the national number when converting into international format. If leading zeros are possible for valid international numbers for this region/country then set this to true. This only needs to be set for the region that is the main_country_for_code and all regions associated with that calling code will use the same setting.

• optional bool mobile_number_portable_region = 32

  This field is set when this country has implemented mobile number portability. This means that transferring mobile numbers between carriers is allowed. A consequence of this is that phone prefix to carrier mapping is less reliable.

• repeated PhoneMetadata metadata = 1

• required int32 country_code = 1

  The country calling code for this number, as defined by the International Telecommunication Union (ITU). Fox example, this would be 1 for NANPA countries, and 33 for France.

• required uint64 national_number = 2

  National (significant) Number is defined in International Telecommunication Union (ITU) Recommendation E.164. It is a language/country-neutral representation of a phone number at a country level. For countries which have the concept of Area Code, the National (significant) Number contains the area code. It contains a maximum number of digits which equal to 15 - n, where n is the number of digits of the country code. Take note that National (significant) Number does not contain National(trunk) prefix. Obviously, as a uint64, it will never contain any formatting (hypens, spaces, parentheses), nor any alphanumeric spellings.

• optional string extension = 3

  Extension is not standardized in ITU recommendations, except for being defined as a series of numbers with a maximum length of 40 digits. It is defined as a string here to accommodate for the possible use of a leading zero in the extension (organizations have complete freedom to do so, as there is no standard defined). However, only ASCII digits should be stored here.

• optional bool italian_leading_zero = 4

  In some countries, the national (significant) number starts with one or more "0"s without this being a national prefix or trunk code of some kind. For example, the leading zero in the national (significant) number of an Italian phone number indicates the number is a fixed-line number. There have been plans to migrate fixed-line numbers to start with the digit two since December 2000, but it has not happened yet. See http://en.wikipedia.org/wiki/%2B39 for more details. These fields can be safely ignored (there is no need to set them) for most countries. Some limited number of countries behave like Italy - for these cases, if the leading zero(s) of a number would be retained even when dialling internationally, set this flag to true, and also set the number of leading zeros. Clients who use the parsing functionality of the i18n phone number libraries will have these fields set if necessary automatically.

• optional int32 number_of_leading_zeros = 8

• optional string raw_input = 5

  This field is used to store the raw input string containing phone numbers before it was canonicalized by the library. For example, it could be used to store alphanumerical numbers such as "1-800-GOOG-411".

• optional PhoneNumber.CountryCodeSource country_code_source = 6

  The source from which the country_code is derived.

• optional string preferred_domestic_carrier_code = 7

  The carrier selection code that is preferred when calling this phone number domestically. This also includes codes that need to be dialed in some countries when calling from landlines to mobiles or vice versa. For example, in Columbia, a "3" needs to be dialed before the phone number itself when calling from a mobile phone to a domestic landline phone and vice versa. Note this is the "preferred" code, which means other codes may work as well.

The source from which the country_code is derived. This is not set in the general parsing method, but in the method that parses and keeps raw_input. New fields could be added upon request.

Used in: PhoneNumber

• FROM_NUMBER_WITH_PLUS_SIGN = 1

  The country_code is derived based on a phone number with a leading "+", e.g. the French number "+33 1 42 68 53 00".

• FROM_NUMBER_WITH_IDD = 5

  The country_code is derived based on a phone number with a leading IDD, e.g. the French number "011 33 1 42 68 53 00", as it is dialled from US.

• FROM_NUMBER_WITHOUT_PLUS_SIGN = 10

  The country_code is derived based on a phone number without a leading "+", e.g. the French number "33 1 42 68 53 00" when defaultCountry is supplied as France.

• FROM_DEFAULT_COUNTRY = 20

  The country_code is derived NOT based on the phone number itself, but from the defaultCountry parameter provided in the parsing function by the clients. This happens mostly for numbers written in the national format (without country code). For example, this would be set when parsing the French number "01 42 68 53 00", when defaultCountry is supplied as France.

Used in: PhoneMetadata

• optional string national_number_pattern = 2

  The national_number_pattern is the pattern that a valid national significant number would match. This specifies information such as its total length and leading digits.

• optional string possible_number_pattern = 3

  The possible_number_pattern represents what a potentially valid phone number for this region may be written as. This is a superset of the national_number_pattern above and includes numbers that have the area code omitted. Typically the only restrictions here are in the number of digits. This could be used to highlight tokens in a text that may be a phone number, or to quickly prune numbers that could not possibly be a phone number for this locale.

• optional string example_number = 6

  An example national significant number for the specific type. It should not contain any formatting information.
