Indonesia Postal Codes

Indonesia Postal Codes

If you are filling out an Indonesia address, use the 5-digit postal code that matches the kelurahan or village area, not just the city. Indonesia has many places with the same broad city name, so the small local area matters. A Jakarta address, for example, is not solved by typing one general Jakarta code.

A realistic central Jakarta address would look like this: Jalan M.H. Thamrin No. 10, Gondangdia, Menteng, Jakarta Pusat 10350, Indonesia. For central Jakarta, codes starting with 10 are common, but 10350 is not a code for all of Jakarta. South Jakarta, West Jakarta, East Jakarta, and North Jakarta use many other codes, and even nearby neighborhoods can differ.

A soft way to read Indonesian codes is this: 10xxx often points around Central Jakarta, 12xxx and 13xxx may appear in other Jakarta areas, 40xxx often shows up around Bandung, 50xxx around Semarang, 60xxx around Surabaya, and 80xxx around Bali. That is useful for spotting obvious mistakes, but it is practical guidance, not an official street-by-street rule.

Pos Indonesia’s postcode search is the practical source to use when you know the province, city or regency, district, and village, and UPU-style addressing guidance for Indonesia also treats the postcode as part of the locality line. The safest code is the one tied to the exact kelurahan, not just the main city.

So if a form only says “Jakarta,” do not automatically use a central code like 10350. Look for the neighborhood, district, or kelurahan first. For outer areas, islands, or rural addresses, keep the province and regency/city line clear, because those details help prevent the code from being guessed too broadly.
