Area Code 748 – Sungai Penuh/Kerinci

Overview of Area Code 748

Area code 748 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the Kerinci Regency and the city of Sungai Penuh in the province of Jambi, on the island of Sumatra. This code is part of the +62 country calling code (ITU-T E.164) and is used for fixed-line (PSTN) services in this region.

Geographic Coverage and Administrative Jurisdiction

The 748 area code covers the administrative areas of:

• Kerinci Regency (Kabupaten Kerinci), including its capital, Siulak.
• Sungai Penuh City (Kota Sungai Penuh), an independent municipality enclaved within Kerinci Regency.

These areas are located in the highlands of central Jambi, near the border with West Sumatra. The region is known for the Kerinci Seblat National Park and the active volcano Mount Kerinci.

Dialing Formats

For callers within Indonesia (domestic calls), the trunk prefix 0 is used before the area code. The national significant number (NSN) for a fixed-line subscriber in this region is 10 digits long, including the leading '0' and the area code.

• Local dialing (within the same area code): Typically, only the subscriber number is dialed (e.g., 12345). However, some areas may require the full number including the area code.
• Domestic long-distance dialing (from other Indonesian cities): Dial 0748 followed by the subscriber number. For example, to call a number in Sungai Penuh, you would dial 0748 12345.
• International dialing (from outside Indonesia): Dial your country's exit code (e.g., 00 or +), then 62, then 748, and the subscriber number. For example, +62 748 12345.

Numbering and Overlays

Subscriber numbers in the 748 area code typically have 5 to 7 digits, depending on the specific exchange and the operator. As of the latest numbering plan, there is no overlay code for this area; 748 remains the sole area code for Kerinci and Sungai Penuh. However, with the growth of fixed-line services, some numbers may be used for VoIP-based fixed lines, but the geographic significance remains.

Caller Instructions

For local callers: If you are calling from within the 748 area, you may be able to dial just the local number, but it is safer to use the full 0748 format for compatibility. For international callers: Always omit the leading '0' when dialing from abroad, and use the +62 country code. Ensure you have the correct subscriber number, as numbers are not portable across geographic area codes in Indonesia.

This area code is essential for businesses and residents in Kerinci and Sungai Penuh, enabling reliable fixed-line communication within the national and international PSTN network.
