Area Code 526 – Tamiang Layang/Tanjung

Overview of Area Code 526

Area code 526 is a geographic National Destination Code (NDC) assigned to the eastern region of Central Kalimantan (Kalimantan Tengah), Indonesia. Specifically, it serves the administrative districts of Barito Timur (East Barito) and Barito Selatan (South Barito), with the principal cities being Tamiang Layang (capital of Barito Timur) and Tanjung (capital of Barito Selatan). This code is part of the Indonesian public switched telephone network (PSTN) and is used for fixed-line services, including both traditional analog lines and some VoIP-based fixed services.

Geographic Coverage and Dialing Formats

The 526 area code covers a sparsely populated but geographically significant region, bordered by the Barito River and surrounded by tropical rainforest. Key towns within this code include Tamiang Layang, Tanjung, Ampah, and Buntok (the latter two are in Barito Selatan). The region is known for its mining and agricultural activities, and telecommunications infrastructure is primarily concentrated in the urban centers.

For local calls within the same area code, subscribers dial only the local subscriber number, which typically consists of 5 to 7 digits. For example, a local call to a fixed line in Tamiang Layang might be dialed as 12345.

For calls from outside the area code but still within Indonesia, callers must dial the trunk prefix 0, followed by the area code and the subscriber number. The international format, as per ITU-T E.164, is +62 526 xxx xxxx (where the leading '0' is dropped). For instance, an international caller would dial +62526 12345 to reach a subscriber in Tamiang Layang.

Caller Instructions

• Local callers (within 526): Dial the subscriber number directly.
• National callers (outside 526): Dial 0 526 followed by the subscriber number.
• International callers: Dial your country's exit code, then 62 526, then the subscriber number.

Overlay and Numbering Considerations

As of the latest ITU-T and BRTI (Indonesian Telecommunication Regulatory Authority) updates, there is no overlay code for 526; it remains the sole area code for this region. However, with the ongoing migration to IP-based networks, some fixed-line numbers may be reachable via VoIP, but the geographic significance of the code remains unchanged. Mobile numbers in Indonesia are assigned separate non-geographic prefixes (e.g., 0811, 0812, etc.) and are not tied to this area code.
