ISO 3166-2:TH

The ISO 3166-2 codes for Thailand describe 76 provinces (changwat). 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 Phatthaya. The purpose of this family of standards is to establish a worldwide series of short abbreviations for places, for use on package labels, containers and such. Anywhere where a short alphanumeric code can serve to clearly indicate a location in a more convenient and less ambiguous form than the full place name. US readers may wish to consider them as the equivalent of worldwide zip or postal codes. Within the Wikipedia, the codes from the country pages link to the pages for the locations they identify.

The numbers 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.
