Area Code 654 – Calang

Geographic Overview

The +62 654 country calling code and area code combination corresponds to the geographic region of Calang, the administrative capital of Aceh Jaya Regency, located in the Aceh province on the northern tip of Sumatra, Indonesia. This area code is allocated under the Indonesian national numbering plan (ITU-T E.164) to the PSTN (Public Switched Telephone Network) and fixed-line services within this specific geographic exchange area.

Coverage and Administrative Jurisdiction

The 654 area code serves the Calang exchange area, which encompasses the urban center of Calang and its surrounding administrative districts (kecamatan) within Aceh Jaya. The region is part of the broader Aceh telecommunications region, which is divided into multiple numbering areas. The 654 code is distinct from other Aceh codes, such as Banda Aceh (0651) and Lhokseumawe (0645), ensuring that calls are correctly routed to the Calang fixed-line network.

Dialing Formats and Instructions

For callers within Indonesia, the national trunk prefix '0' is used before the area code. Therefore, a local call to a fixed-line number in Calang would be dialed as: 0 654 XXX XXXX (where 'XXX XXXX' represents the 6- to 7-digit subscriber number). For example, a typical Calang fixed-line number might be 0 654 210 1234.

For international callers, the Indonesian country code +62 is used, and the leading '0' of the national prefix is omitted. Thus, the international dialing format becomes: +62 654 XXX XXXX. For instance, an international caller would dial +62 654 210 1234 to reach the same number.

Overlay and Numbering Considerations

As of the latest ITU-T and national regulatory updates, there is no overlay code for the Calang area; the 654 code remains the sole geographic code for this region. Subscriber numbers within the Calang exchange are typically 6 to 7 digits long, depending on the specific allocation and the density of the local network. The total length of a national significant number (NSN) for a fixed-line in Indonesia is usually 9 to 10 digits, including the area code but excluding the trunk prefix '0'.

Caller Instructions

Local callers within the same area code can often dial just the subscriber number without the area code, but this depends on the specific local dialing plan. For clarity, it is recommended to always include the area code when dialing from a mobile phone or from outside the Calang exchange. Foreign callers should always use the full international format: +62 654 XXX XXXX.
