Area Code 2535 – Saurimo

Overview of Area Code 2535 (Saurimo)

Area code 2535 is a geographic National Destination Code (NDC) assigned to the city of Saurimo, the capital of Lunda Sul Province in eastern Angola. This code is part of Angola's national numbering plan under the ITU-T E.164 standard, which designates specific prefixes for fixed-line (PSTN) services within defined geographic areas. Saurimo is a key administrative and commercial hub for the region, and its telephone infrastructure supports both local businesses and residential users.

Geographic Coverage and Administration

The 2535 code covers the urban and suburban areas of Saurimo and its immediate surroundings. As a geographic code, it ties the subscriber's number to a physical location, which is essential for routing calls over the traditional circuit-switched network. The code is administered by Angola's national telecommunications regulator, the Instituto Angolano das Comunicações (INACOM), which oversees the allocation and management of numbering resources.

Dialing Formats and Instructions

To call a fixed-line number in Saurimo, the dialing format depends on the caller's location:

• Within Angola (domestic call): Dial the trunk prefix 0, followed by the area code and the subscriber's number. For example, if the local number is 123 456, dial 0 2535 123 456.
• From outside Angola (international call): Dial the international access prefix (e.g., 00 or +), then Angola's country code 244, followed by the area code (without the leading 0) and the subscriber's number. For example, from the United States, dial 011 244 2535 123 456; from most European countries, dial 00 244 2535 123 456.

Note that the leading '0' is a domestic trunk prefix and is not included when dialing from abroad. Subscribers in Saurimo have 9-digit numbers in the format 2535 XXX XXX (including the area code but excluding the trunk prefix).

Overlay and Numbering Considerations

Currently, there is no overlay code for Saurimo; the 2535 code is exclusively used for fixed-line services in the area. However, with the growth of VoIP and mobile services, some numbers may be reachable via IP-based networks, but the geographic significance remains for regulatory and emergency service routing. When dialing from a mobile phone within Angola, the same domestic format applies, but call charges may vary depending on the operator's tariff plan.

Caller Guidance

For local callers within Saurimo, it is common to dial only the 6-digit subscriber number when making local calls, but for clarity and to avoid misdialing, it is recommended to use the full national format. Foreign callers should always use the international format to ensure proper routing. If you encounter difficulties, contact your service provider for assistance with international dialing.
