Regions of Trinidad and Tobago

"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 has codes for the regions of Trinidad and Tobago. Like GEC, it has only one code for Tobago: TT-TOB. An update to ISO 3166-2, dated 2015-11-27, withdraws the ISO codes for Eastern and Western Tobago and replaces them with TT-TOB for Tobago. It also changes the code for Mayaro/Rio Claro from TT-RCM to TT-MRC. The GENC code has not changed to match it. Now that none of the standards show Eastern and Western Tobago separately, I conclude they should be combined.

"Geopolitical Entities and Codes" (GEC) is the successor to FIPS standard 10-4. Update 13 to GEC is dated 2013-09-30. For Trinidad and Tobago, all it does is correct one misspelling.

Update 7 to GEC was issued with the date 2012-02-01. It reflects the changes that have occurred in the country's subdivisions since 1980. It shows Tobago as a single division, though. It also changes the spelling of Port-of-Spain to Port of Spain.

International standard ISO 3166-2 was published on December 15, 1998. It superseded ISO/DIS 3166-2 (draft international standard). For Trinidad and Tobago, the draft standard showed eight counties, three municipalities, and one ward. The final standard shows eleven regions and five municipalities. Most of the codes are different, but the code "SGE" was Saint George in the old scheme and Sangre Grande in the new one. The change in the standard corresponds to an actual change in the administrative division of Trinidad and Tobago.

  • Type: regions (reg), boroughs (bor), cities (cit), ward (wd).
  • HASC: Hierarchical administrative subdivision codes.
  • ISO: Region codes from ISO 3166-2. For full identification in a global context, prefix "TT-" to the code (ex: TT-SIP
    represents Siparia).
  • FIPS: Codes from FIPS PUB 10-4.
  • Pop-2011: 2011-01-09 census (source [5]).
  • Pop-2000: 2000-05-15 census (source [2]).
  • Area: 2000-05-15 census.
  • Former: Pre-1990 divisions corresponding roughly to the territory of the modern division.


Note: the census data subdivide Tobago, not into Eastern and Western regions, but into seven parishes. Eastern Tobago includes the parishes of Saint George (2011 population: 6,875), Saint John (2,825), Saint Mary (3,297), and Saint Paul (6,048). Western Tobago includes Saint Andrew (17,536), Saint David (8,733), and Saint Patrick (15,560).

Postal codes: 

According to this TTPOST  page, Trinidad and Tobago launched a six-digit postal code scheme on 2012-03-28. The numbers are not yet available online. The first two digits of the code identify the main post office for processing deliveries. For example, Diego Martin's post office handles codes beginning with 12.

Territorial extent: 

  1. Tobago consists of the islands of Tobago, Little Tobago, and Saint Giles' Islands.
  2. The other divisions lie mainly on the island of Trinidad. In addition, Saint George includes the islands of Monos, Chacachacare, Gaspar Grande, and Huevos.

The UN LOCODE page  for Trinidad and Tobago lists locations in the country, some of them with their latitudes and longitudes, some with their ISO 3166-2 codes for their subdivisions. This information can be put together to approximate the territorial extent of subdivisions.

Change history: 

  1. In 1900, Trinidad and Tobago was a British colony.
  2. 1945-06: County councils were established. Counties were Caroni, Mayaro, Nariva, Saint Andrew, Saint David, Saint George, Saint Patrick, Tobago, and Victoria. In addition, the borough of Arima and the cities of Port of Spain and San Fernando were independent of any county.
  3. 1962-08-31: Trinidad and Tobago became an independent member of the British Commonwealth.
  4. 1980: Tobago House of Assembly was formed as the organ of local government for Tobago. Status of Tobago changed to ward.

  1. 1990: According to the Ministry of Local Government (source [3]), seven new boroughs or counties were created. I haven't been able to find any documentation on the resulting divisions. Could these be the seven parishes of Tobago?
  2. 1991-10-01: Chaguanas municipality split from Caroni county.
  3. 1992: Local government reorganized into the divisions shown in the table above. Note that the four counties named for saints were all on the island of Trinidad, and have disappeared, but there are now seven parishes named for saints, all on the island of Tobago, and the same four saints are still on the map.
  4. ~2014: I can find no current mention of Tobago being divided into Eastern and Western regions. If they did exist, they must have merged. Their former data were, Eastern Tobago (HASC code TT.ET, ISO code ETO, FIPS code TD11, 2011 population 19,045. 2000 pop. 14,887, area 215 km.², capital Roxborough) and Western Tobago (TT.WT, WTO, TD11, 41,829, 29,303, 88, Scarborough).
