Locale::Codes::Country(3pm)           Perl Programmers Reference Guide           Locale::Codes::Country(3pm)



NAME
       Locale::Codes::Country - standard codes for country identification

SYNOPSIS
          use Locale::Codes::Country;

          $country = code2country('jp' [,CODESET]);        # $country gets 'Japan'
          $code    = country2code('Norway' [,CODESET]);    # $code gets 'no'

          @codes   = all_country_codes( [CODESET]);
          @names   = all_country_names();

          # semi-private routines
          Locale::Codes::Country::alias_code('uk' => 'gb');
          Locale::Codes::Country::rename_country('gb' => 'Great Britain');

DESCRIPTION
       The "Locale::Codes::Country" module provides access to several code sets that can be used for
       identifying countries, such as those defined in ISO 3166-1.

       Most of the routines take an optional additional argument which specifies the code set to use. If not
       specified, the default ISO 3166-1 two-letter codes will be used.

SUPPORTED CODE SETS
       There are several different code sets you can use for identifying countries. A code set may be
       specified using either a name, or a constant that is automatically exported by this module.

       For example, the two are equivalent:

          $country = code2country('jp','alpha-2');
          $country = code2country('jp',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha-2, LOCALE_CODE_ALPHA_2
           This is the set of two-letter (lowercase) codes from ISO 3166-1, such as 'tv' for Tuvalu.

           This is the default code set.

       alpha-3, LOCALE_CODE_ALPHA_3
           This is the set of three-letter (lowercase) codes from ISO 3166-1, such as 'brb' for Barbados.
           These codes are actually defined and maintained by the U.N. Statistics division.

       numeric, LOCALE_CODE_NUMERIC
           This is the set of three-digit numeric codes from ISO 3166-1, such as 064 for Bhutan. These codes
           are actually defined and maintained by the U.N. Statistics division.

           If a 2-digit code is entered, it is converted to 3 digits by prepending a 0.

       fips-10, LOCALE_CODE_FIPS
           The FIPS 10 data are two-letter (uppercase) codes assigned by the National Geospatial-Intelligence GeospatialIntelligence
           Intelligence Agency.

       dom, LOCALE_CODE_DOM
           The IANA is responsible for assigning two-letter (uppercase) top-level domain names to each
           country.

ROUTINES
       code2country ( CODE [,CODESET] )
       country2code ( NAME [,CODESET] )
       country_code2code ( CODE ,CODESET ,CODESET2 )
       all_country_codes ( [CODESET] )
       all_country_names ( [CODESET] )
       Locale::Codes::Country::rename_country  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::Country::add_country  ( CODE ,NAME [,CODESET] )
       Locale::Codes::Country::delete_country  ( CODE [,CODESET] )
       Locale::Codes::Country::add_country_alias  ( NAME ,NEW_NAME )
       Locale::Codes::Country::delete_country_alias  ( NAME )
       Locale::Codes::Country::rename_country_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Country::add_country_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Country::delete_country_code_alias  ( CODE [,CODESET] )
           These routines are all documented in the Locale::Codes::API man page.

       alias_code ( ALIAS, CODE [,CODESET] )
           Version 2.07 included 2 functions for modifying the internal data: rename_country and alias_code.
           Both of these could be used only to modify the internal data for country codes.

           As of 3.10, the internal data for all types of codes can be modified.

           The alias_code function is preserved for backwards compatibility, but the following two are
           identical:

              alias_code(ALIAS,CODE [,CODESET]);
              rename_country_code(CODE,ALIAS [,CODESET]);

           and the latter should be used for consistency.

           The alias_code function is deprecated and will be removed at some point in the future.

           Note: this function was previously called _alias_code, but the leading underscore has been
           dropped. The old name was supported for all 2.X releases, but has been dropped as of 3.00.

           Official home page for the ISO 3166 maintenance agency.

           Unfortunately, they do not make the actual ISO available for free, so I cannot check the alpha-3
           and numerical codes here.

           The source of the official ISO 3166-1 three-letter codes and three-digit codes.

           For some reason, this table is incomplete! Several countries are missing from it, and I cannot
           find them anywhere on the UN site.  I get as much of the data from here as I can.

       https://www.cia.gov/library/publications/the-world-factbook/appendix/print_appendix-d.html
           The World Factbook maintained by the CIA is a potential source of the data.  Unfortunately, it
           adds/preserves non-standard codes, so it is no longer used as a source of data.

       http://www.statoids.com/wab.html
           Another unofficial source of data. Currently, it is not used to get data, but the notes and
           explanatory material were very useful for understanding discrepancies between the sources.
