PT Pos Indonesia (Persero) is Indonesia’s oldest state-owned enterprise, established in 1746, and today it operates as a modern postal, logistics, and financial services provider with a nationwide reach. It has transformed from a traditional mail carrier into a diversified company supporting digital services, logistics, and financial inclusion across the archipelago.
PT Pos Indonesia (Persero) traces its origins back to August 26, 1746, when the first post office was founded in Batavia, now Jakarta, by Governor General G.W. Baron van Imhoff. Initially created to secure correspondence for traders and maintain communication between the Netherlands and the East Indies, the company gradually expanded with additional post offices in Semarang and other key trading hubs. By the late nineteenth century, postal services merged with telegraph operations, and in 1877, Indonesia’s postal system joined the Universal Postal Union, enabling international connectivity. During the colonial and wartime periods, the postal service operated under the Post, Telegraph, and Telephone (PTT) administration, functioning as a public service rather than a commercial entity. Following Indonesia’s independence in 1945, the postal system was taken over by Indonesian staff, marking the beginning of its role as a national institution.
