ISO 3166-2:TH
From Wikipedia, the free encyclopedia
ISO 3166-2:TH is an ISO standard which defines geocodes: it is the subset of ISO 3166-2 which applies to Thailand. It covers the 75 provinces (changwat) and the city of Bangkok, which is both a province and a municipality.
The first part of the code is the ISO 3166-1 country code TH for Thailand, the second part is two-digit-numeric (with trailing zeros). A special non-numeric code is used for the city of Pattaya, which is in the province Chonburi, but other than all other communes it is administrated by a unique City Council.
The numbers used are the same as the postal code for the province, except in the number range 11-19, where one have to subtract 1 to get the postal code from the ISO code. The number codes did change significantly between the first drafts of the ISO 3166-2 standard in 1988 and the first published version of 1993, including three new provinces which were created in the meantime.
The US standard FIPS 10-4 also includes designators for the provinces which use the same style (TH-xx), but the numbers are incompatible with the ISO standard. Thus the decoding table below does not apply to the FIPS codes. In fact the draft of the ISO 3166-2 was based upon the FIPS codes.
The Department of Provincial Administration of the Thai Ministry of Interior uses a coding scheme based upon the ISO 3166-2 numbers to encode all the subsequent subdivisions of the provinces as well - two digits for the districts (Amphoe), two further digits of the communes (tambon), and another two digits for the villages (muban). A trailing 00 marks the upper level division. Thus e.g. 20090000 is the code for the Amphoe Sattahip in the province Chonburi.
The municipal (thesaban) areas are also encoded in a similar way like the Amphoe, only starting with 99 and counting down. The code 99 usually encodes the capital of the province, thus 2099 is the town Chonburi.
