ISO 3166-1

ISO 3166-1 (Codes for the representation of names of countries and their subdivisions – Part 1: Country codes) is a standard defining codes for the names of countries, dependent territories, and special areas of geographical interest. It is the first part of the ISO 3166 standard published by the International Organization for Standardization.

It defines three sets of country codes:[1]

The alphabetic country codes were first included in ISO 3166 in 1974, and the numeric country codes were first included in 1981. The country codes have been published as ISO 3166-1 since 1997, when ISO 3166 was expanded into three parts, with ISO 3166-2 defining codes for subdivisions and ISO 3166-3 defining codes for former countries.[1]

As a widely used international standard, ISO 3166-1 is implemented in other standards and used by international organizations[1] to allow facilitation of the exchange of goods and information.[1] However, it is not the only standard for country codes. Other country codes used by many international organizations are partly or totally incompatible with ISO 3166-1,[1] although some of them closely correspond to ISO 3166-1 codes.

Criteria for inclusion

[edit]

Codes for 249 countries, territories, or areas of geographical interest are assigned in ISO 3166-1.[2] According to the ISO 3166 Maintenance Agency (ISO 3166/MA), the only way to enter a new country name into ISO 3166-1 is to have it registered in one of the following two sources:[1]

To be listed in the bulletin Country Names, a country must be at least one of the following:[3]

The list of names in Country and Region Codes for Statistical Use of the UN Statistics Division is based on the bulletin Country Names and other UN sources.

Once a country name or territory name appears in either of these two sources, it will be added to ISO 3166-1 by default.

The ISO 3166/MA may reserve code elements for other entities that do not qualify for inclusion based on the above criteria.[4] For example, because the European Union is not a country, it is not formally included in ISO 3166-1, but for practical reasons, the ISO 3166/MA has "reserved the two-letter combination EU for the purpose of identifying the European Union within the framework of ISO 3166-1".[5]

Information included

[edit]

ISO 3166-1 is published officially in both English and French. Since the second edition of ISO 3166-1, the following columns are included for each entry:

  1. Country Name – English (or French) short name (all upper-case)
  2. English (or French) short name lower case (title case)
  3. English (or French) full name
  4. Alpha-2 code
  5. Alpha-3 code
  6. Numeric code
  7. Remarks
  8. Independent
  9. Additional information: Administrative language(s) alpha-2 code element(s)
  10. Additional information: Administrative language(s) alpha-3 code element(s)
  11. Additional information: Local short name(s)

Naming and disputes

The country names used in ISO 3166-1 are taken from the two UN sources. Some country names used by the UN, and accordingly by ISO, are disputed:

Coding

[edit]

The codes are chosen, according to the ISO 3166/MA, "to reflect the significant, unique component of the country name in order to allow a visual association between country name and country code".[5] For this reason, common components of country names like "Republic", "Kingdom", "United", "Federal" or "Democratic" are normally not used for deriving the code elements. As a consequence, for example, the United Kingdom is officially assigned the alpha-2 code GB rather than UK, based on its official name "United Kingdom of Great Britain and Northern Ireland" (although UK is reserved on the request of the United Kingdom). Some codes are chosen based on the native names of the countries. For example, Germany is assigned the alpha-2 code DE, based on its native name "Deutschland".

Codes

Each country's alpha-2 code is linked to more information about the assignment of its code elements.

Reserved and user-assigned code elements

[edit]

The officially assigned code elements may be expanded by using either reserved codes or user-assigned codes.[1]

Reserved code elements are codes which have become obsolete, are used in other coding systems such as WIPO ST.3, or are required in order to enable a particular user application of the standard but do not qualify for inclusion in ISO 3166-1. To avoid transitional application problems and to aid users who require specific additional code elements for the functioning of their coding systems, the ISO 3166/MA, when justified, reserves these codes for a certain use for a limited or indeterminate period of time. Codes are usually reserved for former countries, overseas territories, international organizations, and special nationality status. The reserved alpha-2 and alpha-3 codes can be divided into four categories:
(follow the links for the reserved codes of each category)

User-assigned code elements are codes at the disposal of users who need to add further names of countries, territories, or other geographical entities to their in-house application of ISO 3166-1, and the ISO 3166/MA will never use these codes when updating the standard. These codes can be user-assigned:[14]

  • Alpha-2: AA, QM to QZ, XA to XZ, and ZZ
  • Alpha-3: AAA to AAZ, QMA to QZZ, XAA to XZZ, and ZZA to ZZZ
  • Numeric: 900 to 999

User-assigned codes in wide use

Changes

[edit]

The ISO 3166/MA updates ISO 3166-1 when necessary. A country is normally assigned new ISO 3166-1 codes if it changes its name or its territorial boundaries. In general, new alphabetic codes are assigned if a country changes a significant part of its name, while a new numeric code is assigned if a country changes its territorial boundaries. Codes for country names that have been deleted from ISO 3166-1 are published in ISO 3166-3.

ISO formerly announced changes in newsletters which updated the standard, and periodically released new editions which consolidated the newsletter changes. As of July 2013, changes are published in the online catalogue of ISO only, and newsletters are no longer published. Past newsletters remain available via the search option on the ISO website.[16]
