Area Code 2655 – Ondjiva

Geographic Overview and Administrative Jurisdiction

The +244 2655 prefix is a geographic National Destination Code (NDC) assigned to the city of Ondjiva, the capital of Cunene Province in southern Angola. Ondjiva serves as the administrative and commercial hub of the province, bordering Namibia to the south. This code is used for fixed-line telephone services within the municipal area, including the city center and its surrounding peri-urban zones.

Dialing Formats and Caller Instructions

To call a fixed-line subscriber in Ondjiva, the complete international number format is +244 2655 XXX XXX (where X represents the subscriber's local number digits). The NDC '2655' is mandatory for all calls, including local calls placed within the same city.

• International call from abroad: Dial your country's exit code (e.g., 00 or +), then Angola's country code 244, followed by the NDC 2655 and the subscriber's 6-digit number. Example: +244 2655 123 456.
• Domestic call from another Angolan province: Dial 0 (trunk prefix) followed by 2655 and the subscriber number. Example: 0 2655 123 456.
• Local call within Ondjiva: Dial the full NDC and subscriber number: 2655 123 456. The use of the area code is mandatory even for local calls, as there are no separate local exchange codes.

Numbering Plan and Technical Considerations

Angola's national numbering plan follows the ITU-T E.164 recommendation, with a total length of 9 digits for all national significant numbers (excluding the trunk prefix '0'). For Ondjiva, the NDC '2655' is followed by a 6-digit subscriber number, resulting in a 9-digit national number. This fixed geographic code is managed by Angola's regulatory authority, the Instituto Angolano das Comunicações (INACOM).

As of the latest updates, no overlay codes have been introduced for Ondjiva, meaning the 2655 prefix remains exclusive to the geographic area. However, with the ongoing migration of fixed-line services to VoIP and Next-Generation Networks (NGN), calls to this prefix may be routed over IP backbones, but the dialing format remains unchanged for end users.

For callers, it is important to note that the '0' trunk prefix is only used for domestic calls within Angola. International callers must omit the '0' and dial directly the country code and NDC. This standard E.164 format ensures reliable routing across international PSTN and mobile networks.
