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::rename_country('gb' => 'Great Britain');

DESCRIPTION

       This 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.

       dom, LOCALE_CODE_DOM
           The IANA is responsible for delegating management of the top level country domains.
           The country domains are the two-letter (lowercase) codes from ISO 3166 with a few
           other additions.

       un-alpha-3, LOCALE_CODE_UN_ALPHA_3
       un-numeric, LOCALE_CODE_UN_NUMERIC
           The UN maintains a list of codes that is similar, but not identical, to the standard
           ISO 3166 lists.  They maintain a 3-letter code (similar to alpha-3) and a numeric code
           (similar to numeric).

       genc-alpha-2, LOCALE_CODE_GENC_ALPHA_2
       genc-alpha-3, LOCALE_CODE_GENC_ALPHA_3
       genc-numeric, LOCALE_CODE_GENC_NUMERIC
           The GENC codes are the US Government codes that replace the FIPS-11 codes.  They are
           based on, but not identical to the standard ISO 3166 lists.

       NOTE: As of version 3.27, the FIPS code set is no longer supported.  See the
       Locale::Codes::Changes document for details.

           Previously, this table was treated as a source of the ISO 3166 data, but I found that
           the table was incomplete, so I stopped using it.  Later, it was added back in as it's
           own list of codes.

           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.

           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.
