Counties of Taiwan

"Geopolitical Entities, Names, and Codes, Edition 2" (GENC), a U.S. standard that's supposed to correspond to ISO 3166-2, was issued on 2014-03-31. It gives codes for the two counties in Fukien province: TW-KIN for Kinmen and TW-LIE for Lienkiang. Its codes for all the other municipalities match the ISO codes. However, ISO hasn't yet officially issued a code for these two.

The online version of ISO 3166-2 now shows codes for Kaohsiung City, Taichung City, and Tainan City. It also has codes for counties of the same names, with the third letter changed to "Q", although the counties merged with the municipalities in 2010. It has separate codes for Taipei special municipality and Taipei district, and the GENC document uses those same codes for Taipei municipality and New Taipei municipality, respectively. I think their correct identities are Taipei City and New Taipei City special municipalities.

Update 2 to "Geopolitical Entities and Codes" was published on 2010-11-30. For Taiwan, it revokes the province codes and replaces them by a set of county and municipality codes, shown below. Update 4, issued on 2011-04-30, revokes three of the codes that were issued in Update 2: TW11 for Kaohsiung county, TW20 for Taichung county, and TW22 for Tainan county. It also changes the name and status of Taipei county to New Taipei municipality.

Change history:

  1. The Encyclopædia Britannica World Atlas, 1957 edition shows Taiwan subdivided into sixteen counties and five municipalities. It does not include any territory in Fukien province, where Taiwan holds a number of offshore islands. In the list below, I have changed some county names to a more modern spelling, and corrected some evident errors in the data.
  2. The Atlas claims to include data from the 1951 and 1953 censuses, but according to the U.S. Census Bureau's compilation, the first modern census of Taiwan was taken in 1956.

  • Type: cn = county, mu = municipality
  • Population: 1951
  1. ~1952: Yangmingshan municipality split from Taipei county. This change was apparently reversed not long afterward.
  2. Chiayi City and Hsinchu City must have been split from their respective counties between ~1953 and ~1970.
  3. 1967: Taipei municipality split from Taiwan province to become Taipei special municipality.
  4. 1979: Kaohsiung municipality split from Taiwan province to become Kaohsiung special municipality.
  5. ~1989: Capital of Taiwan province moved from Taichung to Chung-hsing-hsin-tsun.
  6. ISO 3166-2 originally (and inadvertently) assigned some duplicate codes. Chiayi county and municipality were both CYI, Hsinchu was HSZ, Kaohsiung was KHH, Taichung was TXG, Tainan was TNN, and Taipei was TPE. Newsletter number I-4, dated 2002-12-10, changed the codes for those six counties, to eliminate the duplicate codes. The new codes are shown in the table below. Even with the revisions, some of the ISO province codes were duplicates of some of the ISO county codes.
