Bakongan is a district (kecamatan) located in the South Aceh Regency (Kabupaten Aceh Selatan), within the province of Aceh on the island of Sumatra.

Dialing Formats and Usage
When calling a fixed-line number in Bakongan from within Indonesia, subscribers must dial the trunk prefix '0' followed by the area code '657' and the subscriber number. The national significant number (NSN) for Bakongan consists of the area code '657' plus a local subscriber number, typically 5 to 7 digits in length, resulting in a total NSN of 8 to 10 digits. For example, a local number might be formatted as 0 657 12345 when dialed domestically.
From an international location, callers must use Indonesia's country code '+62', drop the leading '0', and then dial the area code without the trunk prefix. Thus, the same number would be dialed as +62 657 12345. The plus sign represents the international access prefix, which varies by country (e.g., '011' in the US, '00' in most European countries).
Geographic Significance and Caller Instructions
Bakongan is a relatively rural area, and its numbering is tied to the PSTN infrastructure of the region. The code is not portable outside the geographic area, meaning that numbers with this prefix are tied to a physical location. For local callers within Bakongan, short dialing may be possible without the area code, but it is always safe to use the full national format. For callers from other parts of Indonesia, the trunk prefix '0' is mandatory. International callers should be aware that calls to this region are billed at international rates, and they must ensure they have the correct country and area codes.
As with all geographic codes in Indonesia, overlay plans may be introduced in the future to address number exhaustion, but as of now, no overlay is in effect for Bakongan. Users are advised to verify the correct dialing sequence with their telecom provider.
