Area Code 768 – Tembilahan

Overview of Area Code 768

Area code 768 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the Indragiri Hilir Regency in the province of Riau, Sumatra. The principal city served by this code is Tembilahan, the regency's capital, along with surrounding districts such as Enok, Gaung, and Kateman. As a geographic code, it is used exclusively for fixed-line (PSTN) services, and it does not apply to mobile numbers.

Dialing Formats

When calling a fixed line in Tembilahan from within Indonesia, you must include the trunk prefix 0 followed by the area code and the subscriber number. The local subscriber numbers in Tembilahan typically consist of 5 to 7 digits, making the complete national significant number (NSN) 8 to 10 digits long (excluding the leading 0). The international dialing format for callers outside Indonesia is +62 768 xxx xxxx (or +62 768 xxxxxxx), where the leading 0 is omitted.

For example, a local number in Tembilahan might be 0768 21034. To call this from Jakarta, you would dial 0768 21034. From overseas, you would dial +62 768 21034.

Geographic Coverage and Administration

The 768 area code is administered under Indonesia's national numbering plan, which follows ITU-T E.164 recommendations. It is allocated to the Indragiri Hilir Regency, which is part of Riau Province. The code covers both the urban center of Tembilahan and the rural areas within the regency. As with most Indonesian geographic codes, the 768 area code is not overlaid with another code; it is the sole code for this region.

Caller Instructions

• Local callers within Tembilahan: For calls within the same area code, you may dial only the subscriber number (without the area code) if your telephone service provider supports local dialing. However, for clarity and to avoid misdialing, it is recommended to dial the full national format: 0768 xxxxxxx.
• Callers from other Indonesian cities: Dial the trunk prefix 0, then the area code, then the subscriber number: 0768 xxxxxxx.
• International callers: Dial your country's exit code (e.g., 00 or +), then Indonesia's country code 62, then the area code without the leading 0, and the subscriber number: +62 768 xxxxxxx.

Important Notes

Since 768 is a fixed-line code, it is not used for mobile services. Mobile numbers in Indonesia begin with 8 (e.g., 0811, 0812, 0852, etc.) and are non-geographic. If you receive a call from a number starting with +62 768, it is a fixed-line call from the Tembilahan area. Always verify the number length and format to avoid misdialing.
