{{short description|Three-letter country codes defined in ISO 3166-1}}
'''ISO 3166-1 alpha-3''' codes are three-letter [[country code]]s defined in [[ISO 3166-1]], part of the [[ISO 3166]] standard published by the [[International Organization for Standardization]] (ISO), to represent [[country|countries]], [[dependent territory|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 [[ISO 3166-1 alpha-2|alpha-2]] codes (the third set of codes is [[ISO 3166-1 numeric|numeric]] and hence offers no visual association).<ref>{{cite web| url=http://www.iso.org/iso/country_codes/iso_3166-faqs/iso_3166_faqs_general.htm| title=ISO 3166 – FAQs – General questions| publisher=International Organization for Standardization (ISO) |archive-url=https://web.archive.org/web/20110514070956/http://www.iso.org/iso/country_codes/iso_3166-faqs/iso_3166_faqs_general.htm |archive-date=2011-05-14}}</ref> They were first included as part of the ISO 3166 standard in its first edition in 1974.

==Uses and applications==
The ISO 3166-1 alpha-3 codes are used most prominently in ISO/[[International Electrotechnical Commission|IEC]] 7501-1 for [[machine-readable passport]]s, as standardized by the [[International Civil Aviation Organization]], with a number of additional codes for special passports; some of these codes are currently [[#Indeterminate reservations|reserved and not used at the present stage]] in ISO 3166-1.<ref name="icao">{{citation| url=https://www.icao.int/publications/Documents/9303_p3_cons_en.pdf| title=Doc 9303, Machine Readable Travel Documents, Part 3: Specifications Common to all MRTDs| chapter=Codes for Nationality, Place of Birth, Location of Issuing State/Authority and Other Purposes| edition=Eighth| date=2021| pages=21–23| publisher=International Civil Aviation Organization}}</ref>

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 [[List of international vehicle registration codes|international vehicle registration codes]], which are codes used to identify the issuing country of a vehicle registration plate; some of these codes are currently [[#Indeterminate reservations|indeterminately reserved]] in ISO 3166-1.<ref>{{cite web| url=http://www.unece.org/trans/conventn/Distsigns.pdf| title=Distinguishing signs used on vehicles in international traffic| publisher=United Nations Economic Commission for Europe}}</ref>

===User-assigned code elements===<!--This section is linked from [[ISO 3166-1]]-->
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: {{mono|AAA}} to {{mono|AAZ}}, {{mono|QMA}} to {{mono|QZZ}}, {{mono|XAA}} to {{mono|XZZ}}, and {{mono|ZZA}} to {{mono|ZZZ}}.<ref name="iso-3166-glossary">{{cite web| url=https://www.iso.org/glossary-for-iso-3166.html| title=Glossary for ISO 3166 - Codes for countries and their subdivisions| publisher=ISO}}</ref>

==== Examples ====
The following codes are used in ISO/IEC 7501-1 for special [[machine-readable passport]]s:<ref name="icao" />

* {{mono|EUE}} is used for the [[European Union laissez-passer]]<ref>{{cite web|url=https://www.laissez-passer.eu|title=European Union laissez-passer (video at 0:47)|website=Laissez-passer.eu|access-date=4 June 2016}}</ref>
* {{mono|XOM}} is used to represent the [[Sovereign Military Order of Malta]]
* {{mono|D}}, a single character, is used for [[Germany]].
* {{mono|XPO}} is used for [[Interpol passport|Interpol travel documents]]
* {{mono|XXA}} is used to represent a [[statelessness|stateless person]], as defined in Article 1 of the [[1954 Convention Relating to the Status of Stateless Persons]]
* {{mono|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
* {{mono|XXC}} is used to represent a refugee, other than as defined above
* {{mono|XXX}} is used to represent a person of unspecified nationality

[[List of NATO country codes|NATO STANAG 1059 INT]] is built upon ISO alpha-3 codes, but also defines alpha-2 codes incompatible with ISO 3166-1. It introduces several private use codes for fictional countries and organizational entities:

* {{mono|XXE}} [[SHAPE]]
* {{mono|XXM}} NATO
* {{mono|XXN}} NATO "Blue" Command

===Reserved code elements===<!--This section is linked from [[ISO 3166-1]]-->
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 are divided into the following three categories: [[#Exceptional reservations|exceptional reservations]], [[#Transitional reservations|transitional reservations]], and [[#Indeterminate reservations|indeterminate reservations]].<ref name="iso-3166-glossary"/>

====Exceptional reservations====<!--This section is linked from [[ISO 3166-1]]-->
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:

* {{mono|ASC}} [[Ascension Island]]{{snd}} Reserved on request of [[Universal Postal Union|Universal Postal Union (UPU)]], also used by [[International Telecommunication Union|International Telecommunication Union (ITU)]]
* {{mono|CPT}} [[Clipperton Island]]{{snd}} Reserved on request of [[International Telecommunication Union|ITU]]
* {{mono|CRQ}} [[Sark]]{{snd}} Reserved on request of the United Kingdom
* {{mono|DGA}} [[Diego Garcia]]{{snd}} Reserved on request of ITU
* {{mono|FXX}} [[Metropolitan France|France, Metropolitan]]{{snd}} Reserved on request of France; Officially assigned before being deleted from ISO 3166-1
* {{mono|SUN}} [[Soviet Union|USSR]]{{snd}} From June 2008; Transitionally reserved from September 1992; Officially assigned before being deleted from ISO 3166-1
* {{mono|TAA}} [[Tristan da Cunha]]{{snd}} Reserved on request of [[Universal Postal Union|UPU]]

The following alpha-3 codes were previously exceptionally reserved, but are now officially assigned:

* {{mono|GGY}} [[Bailiwick of Guernsey|Guernsey]]{{snd}} Reserved on request of UPU
* {{mono|IMN}} [[Isle of Man]]{{snd}} Reserved on request of UPU
* {{mono|JEY}} [[Jersey]]{{snd}} Reserved on request of UPU

====Transitional reservations====<!--This section is linked from [[ISO 3166-1]]-->
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:

* {{mono|ANT}} [[Netherlands Antilles]]{{snd}} From December 2010
* {{mono|BUR}} [[Myanmar|Burma]]{{snd}} From December 1989
* {{mono|BYS}} [[Byelorussian Soviet Socialist Republic|Byelorussian SSR]]{{snd}} From June 1992
* {{mono|CSK}} [[Czechoslovakia]]{{snd}} From June 1993
* {{mono|NTZ}} [[Saudi Arabian–Iraqi neutral zone|Neutral Zone]]{{snd}} From July 1993
* {{mono|ROM}} [[Romania]]{{snd}} From February 2002; Code changed to {{mono|ROU}}<ref name="Romania">{{cite web |url = http://www.iso.org/iso/newsletter_v-3_romania.pdf |title = RE: Change of alpha-3 Code Element |author = ISO International Organization for Standardization, ISO 3166 Maintenance Agency |date = 1 February 2002 |work = ISO 3166-1 NEWSLETTER No. V-3 |access-date = 26 June 2017 |archive-url = https://web.archive.org/web/20110722001502/http://www.iso.org/iso/newsletter_v-3_romania.pdf |archive-date = 2011-07-22 |quote = Description of change: Change of the alpha-3 Code element for Romania from ROM to ROU following a request of the Government of Romania.}}</ref>

* {{mono|YUG}} [[Yugoslavia]]{{snd}} From July 2003
* {{mono|ZAR}} [[Zaire]]{{snd}} From July 1997

====Indeterminate reservations====<!--This section is linked from [[ISO 3166-1]]-->
Indeterminately reserved code elements are reserved for use in a particular way, usually due to their presence in other coding systems.
