type:Question
name:What is ISO 3166?
acceptedAnswer:
type:Answer
text:ISO 3166 is an international standard which defines codes representing names of countries and their subdivisions. The standard specifies basic guidelines for the implementation and maintenance of country and subdivisions codes. Most people refer to ISO 3166, but actually it is divided into three parts.
type:Question
name:What are the parts of ISO 3166?
acceptedAnswer:
type:Answer
text:Part 1 establishes codes that represent the current names of countries, dependencies, and other areas of particular geopolitical interest, on the basis of country names obtained from the United Nations. Part 2 establishes codes that represent the names of the principal administrative divisions, or similar areas, of the countries and entities included in ISO 3166-1. Part 3 establishes a code that represents non-current country names, i.e. the country names deleted from ISO 3166 since its first publication in 1974, for example, Yugoslavia or Czechoslovakia. There are also reserved code elements that do not represent a country but reserved for a certain use. If users need code elements to represent country names not included in the code corresponding to this document, the series of letters AA, QM to QZ, XA to XZ, and ZZ, and the series AAA to AAZ, QMA to QZZ, XAA to XZZ, and ZZA to ZZZ respectively, and the series of numbers 900 to 999 are available. Users are advised that, because these code elements are defined by themselves, they are not compatible between different entities.There is no ISO procedure for the assignment of user-assigned code elements.
type:Question
name:Who maintains ISO 3166 codes?
acceptedAnswer:
type:Answer
text:The ISO 3166 Maintenance Agency (MA) is responsible to maintain the officially assigned set of country codes and their subdivisions, which are accessible on the ISO Online Browsing Platform (OBP) at www.iso.org/obp/ The ISO 3166/MA can be contacted at: c/o International Organization for Standardization Chemin de Blandonnet 8; CP 401; 1214 Vernier, Geneva; Switzerland E-mail: [email protected]
type:Question
name:How did ISO 3166 start?
acceptedAnswer:
type:Answer
text:The predecessor codes for country names were developed outside ISO for various purposes. They turned out to be very useful for commerce and communications, but the different lists were not consistent and did not always match. The first ISO country codes were published in ISO 3166:1974.
type:Question
name:How is ISO 3166 used?
acceptedAnswer:
type:Answer
text:There are many uses for ISO 3166. Many organizations use the codes to identify countries unambiguously across languages (e.g. to distinguish between Austria/Australia and Sweden/Switzerland); international organizations often use the codes in logistics, medical information, financial transaction/currency codes, telecommunications, travel, and postal services. By using ISO 3166 codes, clarity is provided in communicating information to people and organizations around the globe, without having to know local languages and dialects. See also How ISO codes connect the world.
type:Question
name:Why are there some code elements for entities that do not meet the definition of country?
acceptedAnswer:
type:Answer
text:There are some entities not currently meeting the definition of country in ISO 3166-1 listed in ISO 3166 due to the history of the standard, and therefore are legacy. However, over the past years, a significant effort has been made to only include countries that have been recognized by the United Nations. Moreover, due to the limited number of two-letter combinations, the ISO 3166/MA assigns country codes very carefully since once a two-letter country code element is assigned and then deleted, it cannot be re-used for 50 years.
