Federal Information Processing Standards Codes for geopolitical entities from the U.S. Federal Information Processing Standard No. 10 "Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions" (also known as FIPS 10). The current FIPSPUB10-4 provides a list of the basic geopolitical entities in the world, together with the principal administrative divisions that comprise each entity. Each basic geopolitical entity is represented by a two-character, alphabetic country code. Each principal administrative division is identified by a four-character code consisting of the two-character country code followed by a two-character administrative division code.
