A country code constitutes a brief alphanumeric identification system for countries and dependent territories. Its principal application lies within data processing and communications protocols. Multiple identification systems have been developed to serve various purposes[VERIFY].
The term "country code" most commonly refers to ISO 3166-1 alpha-2, alongside telephone country codes, which are standardised through the E.164 recommendation issued by the International Telecommunication Union (ITU).

==ISO 3166-1==
The standard [[ISO 3166-1]] defines short identification codes for most countries and dependent areas:

*[[ISO 3166-1 alpha-2]]: two-letter code
*[[ISO 3166-1 alpha-3]]: three-letter code
*[[ISO 3166-1 numeric]]: three-digit code

The two-letter codes are used as the basis for other codes and applications, for example,

*for [[ISO 4217]] [[currency]] codes
*with deviations, for [[country code top-level domain]] names (ccTLDs) on the Internet: [[list of Internet TLDs]].

Other applications are defined in [[ISO 3166-1 alpha-2]].
