Province codes
Numbering within the province
The third and fourth digits are used to distinguish different areas within the province. The last digit is zero for the main post office handling the mail delivery, while other post offices in the area have other numbers.
Outside of Bangkok and Samut Prakan, the postal code xx000 is the postal code for the main post office of Amphoe mueang of each province. The remaining area number runs in the sequence xx110, xx120, xx130, ..., xx190, xx210, ...
Bangkok's number system replaces the previous mail addressing system of Bangkok 1, Bangkok 2, etc. The Bangkok 1 area becomes 10100, Bangkok 2 becomes 10200, etc. There is special case that Bangkok 10 becomes 10310, while Bangkok 11, 12, etc. becomes 10110, 10120, etc. There is no postal area 10000, as the number is assigned to Bangkok Mail Center.
Mail facilities
In 2018 Thailand Post allocated 10 billion baht to construct two new "automated sorting" centers, one in Chonburi Province and the other in Wang Noi District, Ayutthaya Province. Its goal is to fully automate postal and delivery operations as well back office procedures in 2021.
