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 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.
