Postal codes in Thailand

Postal code of a given location can be found on the side of Thai postal box there. In the picture, this is 82220.

Postal codes in Thailand are five digit numbers. The first two digits of the postal code denote the province or special administrative area (e.g., 43120 Phon Phisai, Nong Khai), while the last 3 digits represent the post office within the province.[1] There are exceptions, for example, Bangkok and Samut Prakan province shared the first two digits 10xxx. It's typical to use postal code ended with zero 0 because they are assigned to post office that are responsible for delivering mail to the district (amphoe or khet).[2] For example, mails to Dusit district destinations uses postal code 10300 except within Chitralada Palace where postal code 10303 is used.[3] 10300 is postal code of Dusit Post Office which handles the delivery throughout Dusit district while 10303 is postal code of Chitralada Palace Post Office which does not deliver mails outside the palace.[4] Other post offices in Dusit district exist, such as Bang Krabu Post Office with postal code 10301, the code used for mails to be delivered to P.O. Box in the post office.

Postcodes in Thailand were introduced in February 1982.[2] They are issued by the Ministry of Digital Economy and Society (MDES).

Numbering within the province

The third and fourth digit is used to distinguish different area within the province while 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.[2] The remaining area number runs in the sequence xx110, xx120, xx130, ..., xx190, xx210, ...

Bangkok number system replaces the previous mail addressing system of Bangkok 1, Bangkok 2, etc. 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 while the number is assigned to Bangkok Mail Center.[6]

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.[7]
