Thailand Post (THP) (Thai: ไปรษณีย์ไทย Prai-sa-nee Thai), formerly part of the Communications Authority of Thailand until its privatization in 2003, is a state enterprise that provides postal services in Thailand.
It was established in 1883 as "Dapartment of Mail" by King Rama V. Its first post office was in a large building by the Chao Phraya River, on the north side of Ong-Ang Canal. In 1898, by merging with the Telegraph Department, its name was changed to "Department of Mail and Telegraph". The department was abolished in 1977 and the country's mailing and telegraphing was assumed by the new government-owned company, "Communications Authority of Thailand" (CAT). In 2003, the government separated the communications authority into two companies, "Thailand Post" and "CAT Telecom".
Prior to the operation Thailand Post, there was a limited mail service, mainly for the royal family. Domestic mail travelled by messengers while international mail travelled by steamboat to post offices in nearby countries, such as the Straits Settlements.
The earliest recorded mail from Bangkok dates back only to 1836 when American missionary Dan Beach Bradley sent a letter to his father in a stampless cover. The British Consular Post Office in Bangkok was established by Great Britain in 1858 as a consequence of a treaty signed between Great Britain and Siam (now known as Thailand) on 18 April 1855, in response to a demand by expatriate merchants and missionaries. It ceased to provide service on 1 July 1885, the day Siam joined the Universal Postal Union and started its own international postal service. During that time most of the mail from Bangkok was sent by diplomatic pouch to Singapore for forwarding. On 4 August 1883, the first stamp was issued in Siam.
