!!! Overview
[{$pagename}] is the 2 letter [Country Code].

[{$pagename}] is published by the [International Organization for Standardization] ([ISO]), to represent countries, dependent territories, and special areas of geographical interest. 

[{$pagename}] are the most widely used of the country codes published by [ISO] (the others being [ISO 3166-1 alpha-3] and numeric), and are used most prominently for the Internet's country code top-level domains (with a few exceptions).

[{$pagename}] were first included as part of the standard in its first edition of [ISO 3166].

[{$pagename}] codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented.


[{$pagename}] are used within other codes or [applications], for [example],
* [ISO 4217] [Currency Code]
* [ISO 3901] [International Standard Recording Code] ([ISRC])
* [ISO 6166] [International Securities Identifying Number] ([ISIN])
* [ISO 9362] [Bank Identifier Codes] ([BIC] or [SWIFT code])

* UN/[LOCODE] [United Nations] Code for Trade and Transport Locations and [United Nations] Economic Commission for Europe
* with deviations, for [Country Code] [Top-Level Domain] (ccTLDs) on the Internet: list of Internet TLDs.
** [United Kingdom], whose [{$pagename}] code is [GB], uses .[UK] instead of .gb as its ccTLD, as [UK] is currently exceptionally reserved in [{$pagename}] on the request of the United Kingdom.
