Area Code 2539 – Lunda Sul

Overview of Angola's +244 2539 Geographic Code

The +244 2539 country-code/area-code combination is assigned to the province of Lunda Sul, a geographic region in eastern Angola. Lunda Sul is known for its diamond mining industry, with the city of Saurimo serving as the provincial capital. The code 2539 is a National Destination Code (NDC) within the Angolan numbering plan, conforming to ITU-T E.164 standards. It is used for fixed-line (PSTN) services within the province, and calls to this code are routed to physical telephone exchanges in the region.

Geographic Coverage and Dialing Formats

The 2539 prefix covers the entire province of Lunda Sul, including the capital Saurimo and other municipalities such as Cacolo, Dala, and Muconda. When dialing a fixed-line number in Lunda Sul from within Angola, subscribers must use the national trunk prefix 0 followed by the area code and the subscriber's local number. For example, a local number might be formatted as 0 2539 12345. From outside Angola, callers must use the international access prefix (typically 00 or +), followed by Angola's country code 244, then the area code without the leading zero, and the subscriber number: +244 2539 12345.

Caller Instructions

For local callers within Angola: Always include the trunk prefix '0' before the area code when dialing from a different province. For example, if you are in Luanda and wish to call a fixed line in Saurimo, you would dial 0 2539 12345. If you are calling from within Lunda Sul to another fixed line in the same province, you may be able to dial just the local number, but it is safer to use the full national format to avoid routing issues.

For international callers: Dial your country's international exit code (e.g., 011 from the US, 00 from most European countries), then Angola's country code 244, then the area code 2539 (without the leading zero), and finally the local subscriber number. For instance, a call from the United States would be 011 244 2539 12345. Ensure you omit the leading '0' of the national trunk prefix when calling from abroad.

Overlay and Numbering Considerations

Angola's fixed-line network is undergoing modernization, and number portability is available for fixed lines, meaning that a number with the 2539 prefix may be reassigned to a different operator while retaining the same geographic code. However, the geographic significance remains for routing and emergency services. There are no overlay codes currently in effect for Lunda Sul, so the 2539 prefix uniquely identifies the province. For accurate billing and routing, always verify the complete number with the recipient, as mobile numbers in Angola use different prefixes (e.g., 91, 92, 93) and are non-geographic.
