Area Code 534 – Ketapang

Overview of Area Code 534

Area code 534 is a geographic National Destination Code (NDC) assigned to the Ketapang region in the province of West Kalimantan (Kalimantan Barat), Indonesia. This code is part of the Indonesian public switched telephone network (PSTN) and is used for fixed-line telephone services in the area.

Geographic Coverage and Administrative Jurisdiction

The 534 area code serves the administrative regency of Ketapang, which is located on the western coast of the island of Borneo. It encompasses the capital town of Ketapang and its surrounding districts, including areas such as Delta Pawan, Benua Kayong, and Simpang Hulu. The region is known for its palm oil plantations and mining activities, and the telephone network supports both residential and business communications.

Dialing Formats

When calling a fixed-line number in Ketapang from within Indonesia, the trunk prefix 0 is used, followed by the area code and the local subscriber number. The local numbers typically consist of 5 to 7 digits, making the total national significant number (NSN) length 9 to 11 digits (including the leading 0). For example, a local number might be 12345, and the national dialing format would be 0534 12345.

For international callers, the country code for Indonesia is +62, and the leading trunk prefix is omitted. Thus, the international dialing format becomes +62 534 12345 (or +6253412345 when written without spaces).

Caller Instructions

• Local callers within Ketapang: Depending on the local network configuration, you may be able to dial just the subscriber number (e.g., 12345) without the area code. However, in many cases, the full national format (0534 12345) is required even for local calls.
• Callers from other Indonesian regions: Dial 0534 followed by the subscriber number (e.g., 0534 12345).
• International callers: Dial your country's international access prefix (e.g., 011 from the US, 00 from most countries), then Indonesia's country code 62, then the area code 534 without the leading zero, and finally the subscriber number. For example, from the US you would dial 011 62 534 12345.

Overlay and Numbering Plan Considerations

As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for the Ketapang area. The 534 code is exclusively used for fixed-line services in this region. Mobile numbers in Indonesia are assigned separate non-geographic prefixes (e.g., 0811, 0812, etc.) and are not affected by this area code.

When dialing from abroad, it is essential to drop the trunk prefix '0' and use the country code +62. This ensures proper routing through international gateways. Always verify the current numbering plan with your telecom provider, as local number lengths may vary.
