#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 source of the GENC codes.

#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.
