Area Code 565 – Sintang

Overview of Area Code 565

Area code 565 is a geographic National Destination Code (NDC) assigned to the Sintang region in the province of West Kalimantan (Kalimantan Barat), Indonesia. It serves the administrative capital of Sintang Regency, along with the surrounding districts and rural areas. This code is part of the Indonesian public switched telephone network (PSTN) numbering plan, following the ITU-T E.164 international standard.

Geographic Coverage and Jurisdiction

The 565 area code covers the Sintang Regency, which is located in the eastern part of West Kalimantan, bordering Malaysia (Sarawak). Key towns and districts within this code include Sintang (the regency seat), Dedai, Kayan Hilir, Kelam Permai, and Sepauk. The region is characterized by its proximity to the Kapuas River and its role as a hub for local trade and government services.

Dialing Formats

To call a fixed-line number in Sintang from within Indonesia, you must use the trunk prefix 0 followed by the area code and the subscriber number. The national format is: 0 565 XXXX (where XXXX is the local subscriber number, typically 4 to 6 digits). For example, a local number might be dialed as 0565 12345.

When calling from outside Indonesia, you need to replace the leading 0 with the Indonesian country code +62, and drop the trunk prefix. The international format becomes: +62 565 XXXX. For instance, if the local number is 12345, the international dialing format would be +62 565 12345.

Caller Instructions

• Local callers (within Sintang): For calls to other numbers within the same area code, you may often dial only the subscriber number, depending on the local exchange. However, for clarity and to avoid misdialing, it is recommended to use the full national format: 0565 XXXX.
• National callers (from other Indonesian regions): Dial 0 565 XXXX.
• International callers: Dial your country's international access code (e.g., 00 from many countries, or 011 from the US), then 62 565 XXXX.

Overlay and Numbering Considerations

As of the latest ITU-T and Indonesian regulatory updates, there is no overlay code for the Sintang area. The 565 code remains the sole geographic code for this region. Subscriber numbers within this area are not portable to other geographic areas, but fixed-line numbers may be ported between operators within the same code, subject to national regulations.

Additional Notes

This area code is used exclusively for fixed-line (PSTN) services. Mobile numbers in Indonesia are assigned separate non-geographic prefixes (e.g., 0811, 0821, etc.) and are not related to area code 565. When dialing a Sintang number from a mobile phone, you must still include the area code as per the national dialing plan.
