  1. Country CodesFIPS PUB 10-4 & ISO 3166 UNCLASSIFIED Richard A. Pearsall NCGIS FGDC Coordination Working Group 4 November 2008 UNCLASSIFIED

  2. Agenda • Country Codes - FIPS 10-4 and ISO 3166 • What they are (not the only Country Code “standards”) • How/Why are they different • The Country Code Standards Authority • FIPS 10-4, ISO 3166 Crosswalk • NGA NCGIS Proposal and Transition Planning

  3. FIPS PUB 10-4 FIPS 10-4 - COUNTRIES, DEPENDENCIES, AREAS OF SPECIAL SOVEREIGNTY, AND THEIR PRINCIPAL ADMINISTRATIVE DIVISIONS FIPS 10 is a coding system for entities (geopolitical) Two-character alphabetic country codes (digraph) Issued April 1995 with updates (FIPS 10-3 February 1984, FIPS 10-2 March 1977) Used primarily within the US Government State Department dictates policy NGA Maintenance Authority (issued several updates) Federal Register – Intent to Withdraw (July 1995), Withdrawn by NIST (2 September 2008) Mandated with Sunset tag in the Defense Information Technology Standards Registry (DISR)

  4. ISO 3166 ISO 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- Issued 1974 (5 updates), change notices quarterly (9 published) via UN/3166MA • Also known as ANSI Z39.27-1984 (withdrawn by NISO 1990), FIPS 104-1 (withdrawn by NIST July 29, 1997). Referenced by FIPS 5-2 (Withdrawn by NIST Sept 2, 2008 -New ANSI Standard being worked by Census) • Enables “reserved codes” - Nations can request three-character reserved codes (USA via NISO)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

  6. OMB Circular A-119 Replace FIPS 10-4 aka “FIPS 10-5” The Country Code Standards Authority ISO JTC1 ISO/UN TC46 TC211 3166(MA) 191XX Z39.50 ANSI INCITS NIST - FIPS NISO – Information and Documentation L1 (GIS) FGDC, USGS, NGA, USACE, Oracle, Bentley, LMC, NGC, …..

  7. ISO 3166 - FIPS10-4 Crosswalk

  8. USA USA International Partners NCGIS Proposal • DoD & NGA - Profile ISO 3166-1 trigraph • Includes ISO 3166 trigraph • Includes USA Reserved Codes (geopolitical entities) • Includes USA International “Coalition” Partner codes/reserved codes • Civilian – Profile ISO 3166-1 trigraph • Profile includes only those Countries recognized by the US State Dept. • Includes USA Reserved Codes (geopolitical entities) • Includes USA International Partner reserved codes (GSDI?) ISO 3166 Reserved trigraph codes ISO 3166 trigraph (base)

  9. 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)

  10. 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
