ISO 3166-2:TW

ISO 3166-2:TW is the entry for Taiwan in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.

Main article: ISO 3166-2

Although Taiwan is de facto under the jurisdiction of the Republic of China ISO 3166 lists it as "Taiwan, Province of China".[1]

ISO 3166-2:TW defines codes for the subdivisions of Taiwan located on the islands of Taiwan (Formosa), Penghu (Pescadores), Kinmen, Matsu (Lienchiang), and their subsidiary islands. These areas are under the administration of the government of the Republic of China which resides in Taipei. The government of the People's Republic of China which resides in Beijing also claims these islands but considers Kinmen and Matsu to be within its Fujian Province,[2] not its nominal Taiwan Province (ISO 3166-2 code: CN-TW).

Currently ISO 3166-2:TW lists 13 counties, 3 cities, and 6 special municipalities. Constitutionally the counties and cities are part of the ROC provinces of Taiwan and Fujian, but since the provincial governments were largely streamlined in 1998 these 22 subdivisions are regarded as the principal subdivisions of Republic of China (Taiwan).

ISO 3166-2:TW has not been adopted by the Taipei-based government of the Republic of China which uses the national Code of Household Registration and Conscription Information System (HRCIS Code) to encode the subdivisions of Taiwan.

Format
  • Each code consists of two parts, separated by a hyphen. The first part is TW, the ISO 3166-1 alpha-2 code of Taiwan. The second part is three letters.
  • The divisions in the list are categorized in three types:
    • Cities: Romanized as shih (市) and formerly called "municipalities" in ISO 3166-2. The divisions carry City (市) in their official names.
    • Counties: Romanized as hsien (縣) and formerly called "districts" in ISO 3166-2. The divisions carry County (縣) in their official names.
    • Special municipalities: Romanized as chih-hsia-shih (直轄市). The divisions also carry City (市) in their official names.
  • Taiwan is currently assigned the ISO 3166-2 code CN-TW under ISO 3166-2:CN, as China solely claims it as a province of China.

Current codes

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
