Appendix F: Cross-Reference List of Country Data Codes

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.
