ISO

ISO Subdivisions included in ISO For the following countries, a number of their subdivisions in ISO , most of them dependent territory|dependent territories, are also officially assigned their own country codes in ISO :

ISO 'ISO ' is part of the ISO 3166 standardization|standard published by the International Organization for Standardization (ISO), and defines codes for the names of country|countries, dependent territory|dependent territories, and special areas of geographical interest. The official name of the standard is Codes for the representation of names of countries and their subdivisions ndash; Part 1: Country codes. It defines three sets of country codes:

ISO * ISO alpha-2 – two-letter country codes which are the most widely used of the three, and used most prominently for the Internet's country code top-level domains (with a few exceptions).

ISO * ISO alpha-3 – three-letter country codes which allow a better visual association between the codes and the country names than the alpha-2 codes.

ISO * ISO numeric – three-digit country codes which are identical to those developed and maintained by the United Nations Statistics Division, with the advantage of script (writing system) independence, and hence useful for people or systems using non-Latin alphabet|Latin scripts.

ISO The alphabetic country codes were first included in ISO 3166 in 1974, and the numeric country codes were first included in The country codes have been published as ISO since 1997, when ISO 3166 was expanded into three parts to include codes for subdivisions and former countries.

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

ISO Criteria for inclusion 1 Currently 249 countries, territories, or areas of geographical interest are assigned official codes in ISO According to the ISO 3166 Maintenance Agency (ISO 3166/MA), the only way to enter a new country name into ISO is to have it registered in one of the following two sources:

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

ISO Criteria for inclusion 1 The ISO 3166/MA may #Reserved and user- assigned code elements|reserve code elements for other entities that do not qualify for inclusion based on the above criteria. For example, because the European Union is not a country, it is not formally included in ISO , 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

ISO Naming and code construction 1 The country names used in ISO are taken from the two UN sources mentioned above. Some country names used by the UN, and accordingly by ISO, are subject to dispute:

ISO Naming and code construction 1 *Following the United Nations General Assembly resolution 67/19|recognition of Palestine as a non-member UN state in 2012, the official designation used in ISO was changed from Palestinian territories|Palestinian Territory, Occupied to State of Palestine|Palestine, State of.

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

ISO Officially assigned code elements 1 The following is a complete ISO encoding list of the countries which are assigned official codes. It is listed in alphabetical order by the English short country name (upper/lower case) used by the ISO 3166/MA.– Note: The source actually shows only the Country Name element, in all upper-case. The table here has been upper/lower-cased per Wikipedia standards, but should closely resemble the upper/lower- case elements that are not freely available from the ISO.

ISO Reserved and user-assigned code elements 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 , and the ISO 3166/MA will never use these codes in the updating process of the standard. The following codes can be user-assigned:

Country code top-level domain - Unused ISO codes 1 Almost all current ISO codes have been assigned and do exist in DNS.

Country code top-level domain - Unused ISO codes 1 The code.eh|eh, although eligible as ccTLD for Western Sahara, has never been assigned and does not exist in Domain Name System|DNS. Only one subdomain is still registered in.gb|gb (ISO for the United Kingdom) and no new registrations are being accepted for it. Sites in the United Kingdom generally use.uk|uk (see below).

Country code top-level domain - ASCII ccTLDs not in ISO Several ASCII ccTLDs are in use that are not ISO two-letter codes. Some of these codes were specified in older versions of the ISO list.

Country code top-level domain - ASCII ccTLDs not in ISO *.uk|uk (United Kingdom): The ISO code for the United Kingdom is GB. However, the JANET network had already selected uk as a top-level identifier for its pre-existing JANET NRS|Name Registration Scheme, and this was incorporated into the DNS root..gb|gb was assigned with the intention of a transition, but this never occurred and the use of uk is now entrenched.

Country code top-level domain - ASCII ccTLDs not in ISO *.ac|ac (Ascension Island): This code is a vestige of Internet Assigned Numbers Authority|IANA's decision in 1996 to allow the use of codes reserved in the ISO alpha-2 reserve list for use by the Universal Postal Union. The decision was later reversed, with Ascension Island now the sole outlier. (Three other ccTLDs,.gg|gg (Guernsey),.im|im (Isle of Man) and.je|je (Jersey) also fell under this category from 1996 until they received corresponding ISO 3166 codes in March 2006.)

Country code top-level domain - ASCII ccTLDs not in ISO *.eu|eu (European Union): On September 25, 2000, ICANN decided to allow the use of any two-letter code in the ISO reserve list that is reserved for all purposes

Country code top-level domain - ASCII ccTLDs not in ISO *.tp|tp (the previous ISO code for East Timor): Being phased out in favor of.tl|tl since

ISO :CN - Subdivisions included in ISO Besides being included as subdivisions of China in ISO , Taiwan, Hong Kong, and Macao are also officially assigned their own country codes in ISO

ISO :CN - Subdivisions included in ISO In ISO , Taiwan is listed under the country name Taiwan, Province of China.

ISO numeric 1 'ISO numeric' (or 'numeric-3') codes are three-digit country codes defined in ISO , part of the ISO 3166 standardization|standard published by the International Organization for Standardization (ISO), to represent country|countries, dependent territory|dependent territories, and special areas of geographical interest

ISO numeric 1 The ISO alphabetic codes (ISO alpha-2|alpha-2 and ISO alpha-3|alpha-3) use letters from the English alphabet and are suitable for languages based on the Latin alphabet

ISO numeric - Officially assigned code elements 1 The following is a complete list of the current officially assigned ISO numeric codes, using the English short country names officially used by the ISO 3166 Maintenance Agency (ISO 3166/MA):

ISO numeric - Deleted codes 1 The following numeric codes have been deleted from ISO :

ISO numeric - Deleted codes 1 The following numeric codes were also assigned by the United Nations Statistics Division, but these territories were never officially included in ISO :

ISO numeric - Deleted codes 1 In the UN M.49 standard developed by the United Nations Statistics Division, additional numeric codes are used to represent geographical regions and groupings of countries and areas for statistical processing purposes, but these codes are not included in ISO Unlike alphabetic codes, there are no reserved numeric codes in ISO

ISO :US - Subdivisions included in ISO Besides being included as subdivisions of the United States in ISO , the outlying areas are also officially assigned their own country codes in ISO

ISO alpha-3 1 They allow a better visual association between the codes and the country names than the two-letter ISO alpha- 2|alpha-2 codes (the third set of codes is ISO numeric|numeric and hence offers no visual association)

ISO alpha-3 - Uses and applications 1 The ISO alpha-3 codes are used most prominently in ISO/International Electrotechnical Commission|IEC 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 #Codes currently agreed not to use|reserved and not used at the present stage in ISO

ISO alpha-3 - Uses and applications 1 The United Nations uses a combination of ISO 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

ISO alpha-3 - Officially assigned code elements 1 The following is a complete list of the current officially assigned ISO alpha-3 codes, using the English short country names officially defined by the ISO 3166 Maintenance Agency (ISO 3166/MA):

ISO alpha-3 - Exceptional reservations 1 * FXX Metropolitan France|France, Metropolitan mdash; Reserved on request of France; Officially assigned before being deleted from ISO

ISO alpha-3 - Exceptional reservations 1 * SUN Soviet Union|USSR mdash; From June 2008; Transitionally reserved from September 1992; Officially assigned before being deleted from ISO

ISO alpha-3 - Transitional reservations 1 Transitional reserved code elements are codes reserved after their deletion from ISO 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:

ISO alpha-3 - Indeterminate reservations 1 These code elements are expected eventually to be either eliminated or replaced by code elements within ISO

ISO alpha-3 - Deleted codes 1 Besides the codes currently #Transitional reservations|transitionally reserved and two other codes currently #Exceptional reservations|exceptionally reserved (FXX for Metropolitan France|France, Metropolitan and SUN for Soviet Union|USSR), the following alpha-3 codes have also been deleted from ISO :

ISO alpha-2 1 They are the most widely used of the country codes published by ISO (the others being ISO alpha-3|alpha-3 and ISO numeric|numeric), and are used most prominently for the Internet's country code top-level domains (with a few exceptions)

ISO alpha-2 - Uses and applications 1 The ISO alpha-2 codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented.

ISO alpha-2 - Imperfect implementations 1 Starting in 1985, ISO alpha-2 codes have been used in the Domain Name System as country code top-level domains (ccTLDs). The Internet Assigned Numbers Authority currently assigns the ccTLDs mostly following the alpha-2 codes, but with a few exceptions. For example, the United Kingdom, whose alpha-2 code is GB, uses.uk instead of.gb as its ccTLD, as UK is currently #Exceptional reservations|exceptionally reserved in ISO on the request of the United Kingdom.

ISO alpha-2 - Imperfect implementations 1 The World Intellectual Property Organization|WIPO coding standard ST.3 is based on ISO alpha-2 codes, but includes a number of additional codes for international intellectual property organizations, which are currently #Codes currently agreed not to use|reserved and not used at the present stage in ISO

ISO alpha-2 - Imperfect implementations 1 The European Commission generally uses ISO alpha-2 codes with two exceptions: EL (not GR) is used to represent Greece, and UK (not GB) is used to represent the United Kingdom

ISO alpha-2 - Imperfect implementations 1 The United Nations uses a combination of ISO alpha-2 and ISO alpha- 3|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

ISO alpha-2 - Imperfect implementations 1 Under the newer stability policies, old assigned codes that have been withdrawn from ISO should no longer be reassigned to another country or territory (like it occurred in the past for CS)

ISO alpha-2 - Decoding table 1 The following is a colour-coded decoding table of all ISO alpha-2 codes.

ISO alpha-2 - Officially assigned code elements 1 The following is a complete list of the 249 current officially assigned ISO alpha-2 codes, with the following columns:

Country code - ISO *a three-digit numeric (ISO numeric) code.

ISO :FR - Subdivisions included in ISO Besides being included as subdivisions of France in ISO , the overseas departments and overseas territorial collectivities are also officially assigned their own country codes in ISO

ISO :FR - Subdivisions included in ISO The dependency Clipperton Island (FR- CP) is also ISO alpha- 2#Exceptional reservations|exceptionally reserved the ISO alpha-2 code CP on the request of the International Telecommunication Union.

ISO :FR - Subdivisions included in ISO Metropolitan France (the part of France located in Europe) was previously officially assigned its own set of country codes in ISO , with alpha-2 code FX, before it was deleted from ISO The code is now exceptionally reserved on the request of France.

IETF language tag - ISO and UN M.49 1 Two-letter region subtags are based on codes assigned, or exceptionally reserved, in ISO If the ISO 3166 Maintenance Agency were to reassign a code that had previously been assigned to a different country, the existing BCP 47 subtag corresponding to that code would retain its meaning, and a new region subtag based on UN M.49 would be registered for the new country. UN M.49 is also the source for numeric region subtags for geographical regions, such as 005 for South America.

Table of administrative divisions by country - Administrative divisions with ISO Administrative divisions with ISO are cited for statistics matters even when they do not have a special status (for example, the overseas regions of France).
