FIPS 10-4: Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions (FIPS PUB 10-4) is maintained by the Office of the Geographer and Global Issues (Department of State) and published by the National Institute of Standards and Technology (Department of Commerce). These two-character alphabetic codes are included in the text of the Factbook in the Data code entry under the Government category. FIPS 10-4 codes are intended for general use throughout the US Government, especially in activities associated with the mission of the Department of State and national defense programs.
ISO 3166: Codes for the Representation of Names of Countries (ISO 3166) is prepared by the International Organization for Standardization. ISO 3166 includes two- and three-character alphabetic codes and three-digit numeric codes that may be needed for activities involving exchange of data with international organizations that have adopted that standard. Except for the numeric codes, ISO 3166 codes have been adopted in the US as FIPS 104-1: American National Standard Codes for the Representation of Names of Countries, Dependencies, and Areas of Special Sovereignty for Information Interchange.
Internet: This is a provisional compilation that generally agrees with the ISO 3166 two-character alphabetic codes.
