Postal service in colonial Dutch East Indies was provided by the Post, Telegraph, and Telephone Service (Dutch: Post-, Telegraaf-, en Telefoondienst, PTT), established in 1906.

On 27 September 1945, following the proclamation of Indonesia's independence, the central PTT office in Bandung was seized from occupying Japanese forces.

It became a state-owned company in 1961 and then split in 1965 to form two separate companies, one providing telecommunication services (eventually becoming Telkom Indonesia) and the other mail and currents or giro.

A government decree came into effect on 6 June 1995 to create the current Pos Indonesia.

[6] Pos Indonesia operates in 11 regional divisions across the country, each covering multiple provinces.
