ISO 3166

ISO 3166 has several parts and is used for coding countries and territories. "ISO 3166-1 alpha-2" consists of two letter country codes. These are used in various contexts including in defining locale data and country code top-level domains (ccTLD).

The standard has three parts and several subparts. For most localisation purposes, ISO 3166-1 alpha-2 is the relevant section. This information is freely available (see references). The three parts, with ISO links and other information follow:

• ISO 3166-1:2006 Codes for the representation of names of countries and their subdivisions -- Part 1: Country codes http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=39719
  • Incudes 3 sections:
    • alpha-2 [this is the key section for localisation purposes]
    • alpha-3
    • numeric
  • ISO 3166-1:2006/Cor 1:2007 http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=46123
