Area Code 713 – Prabumulih/Talang Ubi

Overview of Area Code +62 713

Area code 713 is a geographic National Destination Code (NDC) within the Indonesian public switched telephone network (PSTN), assigned under the international country calling code +62. It serves the city of Prabumulih and the surrounding region, including the district of Talang Ubi, located in the southern part of Sumatra. This code is part of the national numbering plan administered by the Indonesian telecommunications regulator (BRTI) and follows the ITU-T E.164 international standard.

Geographic Coverage and Administrative Jurisdiction

The 713 area code covers Prabumulih, an independent city in South Sumatra Province, and extends to Talang Ubi, a district within the Musi Banyuasin Regency. The region is known for its oil and gas industry, with Prabumulih serving as a significant energy hub. The code is used for fixed-line telephone services, including PSTN and VoIP-based fixed lines, and is allocated to local exchange areas that route calls based on geographic location.

Dialing Formats

For local callers within the 713 area, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The typical national format is:

• 0 713 XXXX XXX (where X represents the local subscriber number, typically 7 to 8 digits)

For international callers, the format is:

• +62 713 XXXX XXX (drop the leading 0)

For example, a local number in Prabumulih might be dialed as 0713 123 4567 from within Indonesia, and as +62 713 123 4567 from abroad.

Overlay Considerations and Numbering

As of the latest updates, there is no overlay code for the 713 area; it remains a standalone geographic code. However, subscribers in the region may have the option to use VoIP services that present a 713 number, but the underlying routing remains location-independent for IP-based calls. It is important to note that with the growth of mobile telephony, fixed-line usage has declined, but the code remains active for business and residential landlines.

Caller Instructions

For local callers within the 713 area, dialing another fixed line in the same area typically requires only the subscriber number, but it is recommended to use the full national format to avoid misrouting. For callers from other regions in Indonesia, dial 0713 followed by the subscriber number. For international callers, always use the plus sign (+) or the international access prefix of your country, followed by 62, then 713, and the subscriber number. Ensure you omit the leading 0 of the area code when dialing from abroad.
