SPECIAL SOVEREIGNTY, AND THEIR PRINCIPAL ADMINISTRATIVE DIVISIONS

ISO 3166ISO 3166 - Codes for the representation of names of countries and
their subdivisions • ISO 3166 is a coding system for country names• two- (digraph) and three-character (trigraph) alphabetic country codes,
three-digit -numeric country codes, and spelled-out country names• Managed by ISO/Geneva - Issued 1974 (5 updates), change notices
quarterly (9 published) via UN/3166MA• Also known as ANSI Z39.27-1984 (withdrawn by NISO 1990), FIPS 104-
1 (withdrawn by NIST July 29, 1997). Referenced by FIPS 5-2 (Withdrawn by NIST Sept 2, 2008 -New ANSI Standard being worked by Census)
• Enables “reserved codes” - Nations can request three-character reserved codes (USA via NISO)
• Mandated in the DISR• Use – Finance and Commerce, internet-ccTLD [.us], European
Commission/Union, IC Security Markings/DoD Message Clearance traffic, STANAGS (1059Ed8), DoD Coalition partners, numerous international commercial vendors. Normative Reference in many ISO (i.e. 191XX) and GeoINT Standards. Partial harmonization - Postal Unions, International Vehicle License plates, IOC

Recommended Transition Plan From FIPS 10-4 to ISO 3166 Trigraphs
• Strongly recommend transitioning to a profile of ISO 3166-1 trigraph codes– Reserved codes available to accommodate State Dept “geopolitical
entities” and international partner exchange requirements– Many Coalition Partners have adopted 3166 trigraph– Broad use of the trigraph already exits, and would better facilitate
interoperability• Recommend the “Transition” time to occur within the next
four years– A change request has been approved to change the current status of
the FIPS 10-4 in the DISR to mandated sunset, which is not a permanent state in the DISR
• Recommend that any new coding identify which Country Code Standard is being used (i.e., the code AG is used differently in 10-4 and 3166, where one represents Algeria and the other Antigua and Barbuda)

Recommended Transition Plan From FIPS 10-4 to ISO 3166 Digraphs
• If resource constrictions require continued use of a two-letter code for the immediate future, profile the ISO 3166-1 digraph
• Consequences to transition to ISO 3166-1 digraph– There are no reserved codes available to extend the existing set– There is minimal relationship between the digraphs of FIPS 10-4 and ISO
3166-1– Mappings available between FIPS 10-4 and ISO 3166-1 digraph– Mappings available between ISO 3166-1 digraph/trigraph– Recommend programs develop their transition plan to profile ISO 3166-1
trigraph• Recommend the “Transition” time to occur within the next four years
– A change request has been submitted to change the current status of the FIPS 10-4 in the DISR to mandated sunset, which is not a permanent state in the DISR
• Recommend that any new coding identify which Country Code Standard is being used
