NAME

Locale::Country - standard codes for country identification

SYNOPSIS

   use Locale::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::Country::alias_code('uk' => 'gb');
   Locale::Country::rename_country('gb' => 'Great Britain');

DESCRIPTION

The "Locale::Country" module provides access to several code sets that can be used for identifying countries, such as those defined in

Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default

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.

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

ROUTINES

all_country_codes ( [

Locale::Country::rename_country_code (

[,CODESET] )

Locale::Country::add_country_code_alias (

CODE ,NEW_CODE

[,CODESET] )

Locale::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.

For some reason, this table is incomplete! Several countries are missing from it, and I cannot find them anywhere on the

The World Factbook maintained by the

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.
