📍 Geographic Location of Amuntai
Overview of Area Code 527
Area code 527 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the Amuntai region in South Kalimantan province. This code is part of the closed numbering plan for fixed-line services, meaning that all local calls within the same NDC require only the subscriber number, while calls from outside the area must include the trunk prefix 0 followed by the area code.
Geographic Coverage and Administrative Jurisdiction
The 527 area code serves the administrative regency of Hulu Sungai Utara, with Amuntai as its capital. This region is situated in the eastern part of South Kalimantan, bordered by the Meratus Mountains to the west and the Barito River to the east. The code also covers surrounding districts such as Babirik, Danau Panggang, and Sungai Pandan, which are part of the same local access network.
Dialing Formats
For local callers within the 527 area, only the subscriber number (typically 5 to 7 digits) is dialed. For example, to reach a local business, one would dial 123456 directly. For calls originating from outside the area code but within Indonesia, the trunk prefix 0 must be added, followed by the area code and subscriber number: 0-527-123456. International callers must use the Indonesian country code +62, omitting the leading trunk zero: +62-527-123456.
Numbering Structure and Overlays
Subscriber numbers within the 527 NDC are typically 5 to 7 digits long, resulting in a total national significant number (NSN) length of 8 to 10 digits when combined with the area code. As of the latest ITU-T E.164 database, there are no overlay codes or additional NDCs assigned to the same geographic area, meaning that 527 remains the sole code for fixed-line services in the Amuntai region. This simplifies dialing procedures and reduces the need for 10-digit dialing within the area.
Caller Instructions
For local callers: simply dial the subscriber number without any prefix. For domestic long-distance callers: dial 0 followed by 527 and the subscriber number. For international callers: dial your country's exit code (e.g., 00 from most countries), then 62, then 527, and the subscriber number. Remember to drop the leading zero of the area code when calling from abroad. This ensures proper routing through the Indonesian PSTN and VoIP networks.
