Federal Information Processing Standard (FIPS) two-letter country codes (FIPS 10-4) are used by the US Government for data processing, and in the CIA World Factbook. Note that they are not the same as ISO 3166-1 country codes. ISO 3166-1 codes are used for top-level domain names.

The following is a list of FIPS two-letter codes for independent states (including the Republic of China (Taiwan), North Korea, and other states not recognized by the US). There are also codes for dependent territories, but these are not listed here. The standard also includes codes for the top-level subdivision of the countries, similar but usually incompatible with the ISO 3166-2 standard.
