Area Code 650 – Sinabang

Overview of Area Code 650 (Sinabang, Indonesia)

Area code 650 is a geographic destination code assigned to the city of Sinabang, the capital of the Simeulue Regency, located in the province of Aceh, Indonesia. This code is part of the national numbering plan administered by the Indonesian Telecommunication Regulatory Authority (BRTI) under the ITU-T E.164 standard. It is used for fixed-line (PSTN) services within the Sinabang exchange area and its surrounding administrative districts.

Geographic Coverage and Jurisdiction

The 650 area code covers the entire Simeulue Island, including the administrative districts of Simeulue Timur, Simeulue Tengah, Simeulue Barat, and the smaller islands within the regency. The primary city served is Sinabang, which functions as the main economic and administrative hub. The numbering area is classified as a geographic allocation, meaning that the prefix is tied to a physical location and is used exclusively for fixed-line services.

Dialing Formats

For local callers within the 650 area code, the number is dialed as a 7-digit subscriber number (e.g., 123 4567). For calls originating from outside the 650 area but still within Indonesia, callers must dial the trunk prefix 0, followed by the area code and the subscriber number: 0 650 123 4567. International callers from abroad must dial the Indonesian country code +62, then the area code without the leading zero, followed by the subscriber number: +62 650 123 4567.

Caller Instructions

• Local callers (within Sinabang): Dial the 7-digit subscriber number directly.
• National callers (outside 650): Dial 0650 followed by the subscriber number.
• International callers: Dial +62 650 followed by the subscriber number.

Overlay and Numbering Considerations

As of the latest BRTI numbering plan updates, there is no overlay code for the 650 area. The area code is unique to Sinabang and does not share numbering resources with other regions. Subscriber numbers in this area are typically 7 digits long, and the total length of a national significant number (NSN) is 10 digits (including the leading 0). The code is exclusively used for fixed-line services; mobile numbers in Indonesia are assigned separate non-geographic prefixes (e.g., 0811, 0821, etc.) and are not affected by this area code.

Practical Usage

For businesses and residents in Sinabang, having a 650 number signifies a local presence and is essential for accessing fixed-line services such as PSTN telephony and ADSL internet. When contacting services in Sinabang from overseas, it is crucial to use the correct international format to avoid misdialing. Always verify the subscriber number length and include the area code when dialing from outside the local area.
