ISO 3166-1
ISO 3166-1, as part of the ISO 3166 standard, provides codes for the names of countries and dependent areas. It was first published in 1974 by the International Organization for Standardization (ISO) and defines three different codes for each area:
- ISO 3166-1 alpha-2, a two-letter system with many applications, most notably the Internet top-level domains (ccTLD) for countries (with some exceptions).
- ISO 3166-1 alpha-3, a three-letter system.
- ISO 3166-1 numeric, a three-digit numerical system, which is identical to that defined by the United Nations Statistical Division.
244 countries and territories have formal codes. According to the Maintenance Agency for ISO 3166 country codes, a country or territory must be listed in the United Nations Terminology Bulletin Country Names or Country and Region Codes for Statistical Use of the UN Statistics Division. To be listed in the bulletin Country Names a country or territory must be any of the following:
- a United Nations member state,
- a member of any of the UN specialized agencies or
- a party to the Statute of the International Court of Justice.
A country or territory generally gets new alpha codes if its name changes, whereas a new numeric code is associated with a change of boundaries. Some codes in each series are reserved, for various reasons; obsolete codes may be kept as reserved, borders may be considered likely to change, and some overseas territories have reserved codes of their own.
ISO 3166-1 is not the only standard for country codes. The IOC and FIFA have their own lists (see List of IOC country codes and List of FIFA country codes) of three-letter codes which mostly correspond to the ISO 3166-1 alpha-3 codes.

ISO 3166-1 code list, sorted by English short name of country or territory
The following is a complete ISO 3166-1 encoding code list in alphabetical order by the English short country names officially used by the ISO 3166 Maintenance Agency (ISO 3166/MA). The ISO 3166/MA uses country names from United Nations sources [1], and hence, names such as "Palestinian Territory, Occupied" and "Taiwan, Province of China" reflect the countries' political status within the UN.
The table includes formal codes only. For reserved codes, see ISO 3166-1 alpha-2#Reserved code elements and ISO 3166-1 alpha-3#Reserved code elements. ISO 3166-1 does not have reserved numeric codes.
