ISO 3166-1 alpha-3
From Wikipedia, the free encyclopedia
ISO 3166-1 alpha-3 codes are three-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They allow a better visual association between the codes and the country names than the two-letter alpha-2 codes (the third set of codes are numeric and hence offers no visual association).[1] They were first included as part of the ISO 3166 standard in its first edition in 1974.

[edit] Uses and applications
The ISO 3166-1 alpha-3 codes are used most prominently in ISO/IEC 7501-1 for machine-readable passports, as standardized by the International Civil Aviation Organization, with a number of additional codes for special passports; some of these codes are currently reserved and not used at the present stage in ISO 3166-1.[2]
The United Nations uses a combination of ISO 3166-1 alpha-2 and alpha-3 codes, along with codes that pre-date the creation of ISO 3166, for international vehicle registration codes, the codes on the oval stickers used to identify foreign road vehicles; some of these codes are currently indeterminately reserved in ISO 3166-1.[3]
[edit] Current codes
[edit] Officially assigned code elements
The following is a complete list of the current officially assigned ISO 3166-1 alpha-3 codes, using the English short country names officially used by the ISO 3166 Maintenance Agency (ISO 3166/MA):
[edit] User-assigned code elements
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 in the updating process of the standard. The following alpha-3 codes can be user-assigned: AAA to AAZ, QMA to QZZ, XAA to XZZ, and ZZA to ZZZ. For example, the following codes are used in ISO/IEC 7501-1 for special machine-readable passports:[2]
- XOM is used to represent the Sovereign Military Order of Malta
- XXA is used to represent a stateless person, as defined in Article 1 of the 1954 Convention Relating to the Status of Stateless Persons
- XXB is used to represent a refugee, as defined in Article 1 of the 1951 Convention Relating to the Status of Refugees as amended by the 1967 Protocol
- XXC is used to represent a refugee, other than as defined above
- XXX is used to represent a person of unspecified nationality
[edit] Reserved code elements
Reserved code elements are codes which have become obsolete, 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 which it undertakes not to use for other than specified purposes during a limited or indeterminate period of time. The reserved alpha-3 codes can be divided into the following four categories: exceptional reservations, transitional reservations, indeterminate reservations, and codes currently agreed not to use.
[edit] Exceptional reservations
Exceptionally reserved code elements are codes reserved at the request of national ISO member bodies, governments and international organizations, which are required in order to support a particular application, as specified by the requesting body and limited to such use; any further use of such code elements is subject to approval by the ISO 3166/MA. The following alpha-3 codes are currently exceptionally reserved:
- ASC Ascension Island — Reserved on request of UPU, also used by ITU
- CPT Clipperton Island — Reserved on request of ITU
- DGA Diego Garcia — Reserved on request of ITU
- FXX France, Metropolitan — Reserved on request of France; Previously officially assigned
- SUN USSR — Exceptionally reserved from 2008-06; Previously officially assigned, then transitionally reserved from 1992-09
- TAA Tristan da Cunha — Reserved on request of UPU
The following alpha-3 codes were previously exceptionally reserved, but are now officially assigned:
- GGY Guernsey — Reserved on request of UPU; Officially assigned since 2006
- IMN Isle of Man — Reserved on request of UPU; Officially assigned since 2006
- JEY Jersey — Reserved on request of UPU; Officially assigned since 2006
[edit] Transitional reservations
Transitional reserved code elements are codes reserved after their deletion from ISO 3166-1. These codes may be used only during a transitional period of at least five years while new code elements that may have replaced them are taken into use. These codes may be reassigned by the ISO 3166/MA after the expiration of the transitional period. The following alpha-3 codes are currently transitionally reserved:
- BUR Burma — From 1989-12
- BYS Byelorussian SSR — From 1992-06
- CSK Czechoslovakia — From 1993-06
- NTZ Neutral Zone — From 1993-07
- ROM Romania — From 2002-02; Code changed to ROU
- SCG Serbia and Montenegro — From 2006-09
- TMP East Timor — From 2002-05
- YUG Yugoslavia — From 2003-07
- ZAR Zaire — From 1997-07
[edit] Indeterminate reservations
Indeterminately reserved code elements are codes used to designate road vehicles under the 1949 and 1968 United Nations Conventions on Road Traffic but differing from those contained in ISO 3166-1. These code elements are expected eventually to be either eliminated or replaced by code elements within ISO 3166-1. In the meantime, the ISO 3166/MA has reserved such code elements for an indeterminate period. Any use beyond the application of the two Conventions is discouraged and will not be approved by the ISO 3166/MA. Moreover, these codes may be reassigned by the ISO 3166/MA at any time. The following alpha-3 codes are currently indeterminately reserved:
- ADN Aden
- BDS Barbados
- BRU Brunei
- CDN Canada
- EAK Kenya
- EAT Tanganyika [Part of Tanzania, United Republic of]
- EAU Uganda
- EAZ Zanzibar [Part of Tanzania, United Republic of]
- GBA Alderney
- GBG Guernsey
- GBJ Jersey
- GBM Isle of Man
- GBZ Gibraltar
- GCA Guatemala
- HKJ Jordan
- MAL Malaysia
- RCA Central African Republic
- RCB Congo, People's Republic of
- RCH Chile
- RMM Mali
- RNR Zambia
- ROK Korea, Republic of
- RSM San Marino
- RSR Southern Rhodesia [now Zimbabwe]
- SLO Slovenia
- SME Surinam
- TMN Turkmenistan
- WAG Gambia
- WAL Sierra Leone
- WAN Nigeria
- ZRE Zaire
The following alpha-3 code was previously indeterminately reserved, but has been reassigned to another country as its official code:
[edit] Codes currently agreed not to use
In addition, the ISO 3166/MA will not use the following alpha-3 codes at the present stage, as they are are used in ISO/IEC 7501-1 for special machine-readable passports:
- GBD identifies a British Passport holder who is a "dependent territories citizen"
- GBN identifies a British Passport holder who is an "Overseas National"
- GBO identifies a British Passport holder who is an "Overseas Citizen"
- GBP identifies a British Passport holder who is a "Protected Person"
- GBS identifies a British Passport holder who is a "Subject"
- UNA is used as a substitute for nationality where the holder is an Official of a Specialized Agency of the UN Organization
- UNK identifies Kosovo residents to whom travel documents were issued by the United Nations Interim Administration in Kosovo (UNMIK)
- UNO is used to designate the UN Organization as the issuer and used as a substitute for nationality where the holder is an Official of the UN Organization
