Locale::Codes::Country(3) standard codes for country identification


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');


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.


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:

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

This is the default code set.

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.
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.

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.

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


code2country ( CODE [,CODESET] [,'retired'])
country2code ( NAME [,CODESET] [,'retired'])
country_code2code ( CODE ,CODESET ,CODESET2 )
all_country_codes ( [CODESET] [,'retired'])
all_country_names ( [CODESET] [,'retired'])
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 in the December 2014 release.

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.
