ISO 3166-1 alpha-2

ISO 3166-1 alpha-2 codes are two-letter country codes in the ISO 3166-1 standard to represent countries and dependent territories. They are published by the International Organization for Standardization (ISO) as part of its ISO 3166 standard. They are the most widely used of the country codes published by ISO, and are used most prominently for country code top-level domains (with a few changes). They were first included as part of the ISO 3166 standard in its first edition in 1974.

Uses and applications

The codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented.

Perfect implementations

The two-letter ISO 3166-1 codes are used in:

Imperfect implementations

Starting in 1985, two-letter codes have been used in the domain name system as country code top-level domains (ccTLDs). Nowadays, the Internet Assigned Numbers Authority assign the ccTLDs, mostly following the ISO 3166-1 alpha-2 codes, but with a few exceptions (e.g., the United Kingdom requested an exceptional reservation of .uk for their ccTLD instead of their native .gb)

The WIPO coding standard ST.3 uses alpha-2 codes for encoding states, other entities and intergovernmental organizations (and their Patent/Trademark Offices), but includes a number of additional codes. For these additional codes, see the section Codes currently agreed not to use.

NATO country codes are also based on ISO 3166-1 alpha-2.

Changes to ISO 3166-1 alpha-2 are tracked by ISO 3166-3.

User-assigned code elements

The following alpha-2 codes can be user-assigned: AA, from QM to QZ, from XA to XZ, and ZZ. These code elements are 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 them in the updating process of the standard. For example:

  • UN/LOCODE assigns XZ to Installations in International Waters.
  • The Directorate General of Customs of the Ministry of Finance of the Republic of China administering Taiwan assigns four private-use codes for the statistic needs:

Reserved code elements

Reserved code elements are codes which, while not ISO 3166-1 codes, are in use for some applications in conjunction with the ISO 3166 codes. The ISO 3166/MA therefore reserves them, so that they are not used for new official ISO 3166 codes, thereby creating conflicts between the standard and those applications. The alpha-2 reserved code elements list is divided into the following four categories.

Exceptional reservations

Exceptionally reserved alpha-2 code elements are reserved permanently at the request of national ISO member bodies, governments and international organizations because they are needed for particular purposes. ISO 3166/MA only authorizes their use for the particular purpose for which they were established. The following alpha-2 codes are currently exceptionally reserved:

Code Country name Notes
AC Ascension Island Reserved on request of UPU
Used as a ccTLD
CP Clipperton Island Reserved on request of ITU
DG Diego Garcia Reserved on request of ITU
EA Ceuta and Melilla Reserved on request of WCO to represent area outside EU customs territory
EU European Union Originally reserved on request of ISO 4217/MA to provide country code for Euro
Later extended for use in the ISO 6166 International Securities Identification Number (ISIN) system
Later extended by ISO 3166/MA to any application needing to represent the name European Union
Used as a ccTLD
FX France, Metropolitan Reserved on request of France
IC Canary Islands Reserved on request of WCO to represent area outside EU customs territory
TA Tristan da Cunha Reserved on request of UPU
UK United Kingdom Reserved on request of the United Kingdom
Used as a ccTLD

The following three codes were also under exceptional reservation, until the update from 2006-03-29 included them in the standard as official codes:

Code Country name Notes
GG Guernsey Reserved on request of UPU. Used as a ccTLD
IM Isle of Man Reserved on request of UPU. Used as a ccTLD
JE Jersey Reserved on request of UPU. Used as a ccTLD

Transitional reservations

A transitional reservation refers to a code which was formerly present in ISO 3166, but which since has been deleted. It will be maintained as a transitional reservation for at least five years, for the sake of users who still need to refer to the former entity or whose systems have not yet been updated to refer to the new code. The following alpha-2 codes are currently transitionally reserved:

Code Country name Date of reservation Notes
BU Burma December 1989
CS Serbia and Montenegro September 2006 CS previously represented Czechoslovakia
NT Neutral Zone July 1993
SF Finland September 1995 Finland currently uses the code FI
SU U.S.S.R. September 1992 Still used as a ccTLD
TP East Timor May 2002 Still used as a ccTLD
YU Yugoslavia July 2003 Still used as a ccTLD
ZR Zaire July 1997

Indeterminate reservations

The indeterminately reserved alpha-2 code elements are code elements used to identify vehicles under the 1949 and 1968 United Nations Road Traffic Conventions. These codes differ from those used in ISO 3166. The ISO 3166/MA hopes that these codes will eventually be phased out and that ISO 3166-1 codes will be used instead; but in the meantime they are reserved, to avoid conflicts between ISO 3166-1 and the Conventions, and to facilitate any transition from the Convention codes to ISO 3166-1 codes. However, they can be reassigned at any time by the ISO 3166/MA. The following alpha-2 codes are currently indeterminately reserved:

Code Country
DY Benin 1
EW Estonia 1
FL Liechtenstein 2
JA Jamaica 3
LF Libya Fezzan 2
PI Philippines 3
RA Argentina 3
RB Bolivia 2,5
RB Botswana 3,5
RC China 3
RH Haiti 1
RI Indonesia 3
RL Lebanon 3
RM Madagascar 3
RN Niger 4
RP Philippines 4
WG Grenada 1
WL Saint Lucia 1
WV Saint Vincent 1
YV Venezuela 1

The following codes have been reassigned:

Code Country
LT Libya Tripoli 2 — Reassigned to Lithuania
ME Western Sahara 2 — Reassigned to Montenegro
RU Burundi 2 — Reassigned to Russian Federation

Notes:

  1. Code notified to United Nations Secretary-General under 1949 and/or 1968 Road Traffic Conventions
  2. Code in use for road transport purposes, but not notified to United Nations Secretary-General under 1949 Road Traffic Convention
  3. Code under 1949 Road Traffic Convention
  4. Code under 1968 Road Traffic Convention
  5. This code is in use to refer to both Bolivia and Botswana

Codes currently agreed not to use

In addition, the ISO 3166/MA has undertaken, for the time being, not to use the following alpha-2 codes from WIPO Standard ST.3. However, this undertaking is not classified as a transitional, indeterminate or transitional reservation, since the codes do not refer to countries, dependent areas or other geographic regions or localities:

Code Organization
AP African Regional Intellectual Property Organization
BX Benelux Trademarks and Design Offices
EF Union of Countries under the European Community Patent Convention
EM European Trademark Office
EP European Patent Organization
EV Eurasian Patent Organization
GC Patent Office of the Cooperation Council for the Arab States of the Gulf (GCC)
IB International Bureau of WIPO
OA African Intellectual Property Organization
WO World Intellectual Property Organization

WIPO Standard ST.3 actually uses EA to code the Eurasian Patent Organization. However, ISO 3166/MA has stated it cannot guarantee to reserve the code EA from use, since it is already used for customs purposes to represent Ceuta and Melilla. ISO 3166/MA proposed in 1995 that EV be used by WIPO for the purpose of representing the Eurasian Patent Organization; however, this request was not honoured by WIPO.

Other withdrawn codes

Besides the codes currently transitionally reserved and FX (now exceptionally reserved), these alpha-2 codes have also been withdrawn since the first edition of ISO 3166 in 1974:
