Area Code 779 – Foumbouni

Overview of Comoros +269 779 Geographic Code

The +269 779 prefix is a geographic National Destination Code (NDC) assigned to the town of Foumbouni, located on the island of Grande Comore (Ngazidja) in the Union of the Comoros. Foumbouni serves as the administrative center of the Mbadjini-Ouest region and is one of the principal coastal settlements on the island's western coast. This code is part of Comoros' national numbering plan, which adheres to ITU-T E.164 recommendations, and is used exclusively for fixed-line (PSTN) services within this specific geographic area.

Dialing Formats and Usage

To call a fixed-line subscriber in Foumbouni from abroad, you must dial the international prefix (00 or +), followed by the Comoros country code 269, then the NDC 779, and finally the subscriber's local number. For example, a complete international number would appear as +269 779 XX XX. The total length of a Comorian national significant number (NSN) is seven digits, meaning that after the country code and NDC, there are four additional digits. When dialing locally within Comoros, callers must still include the NDC, as the country uses a closed dialing plan; therefore, a local call to Foumbouni would be dialed as 779 XX XX from any other part of the country.

Geographic Coverage and Administrative Context

The 779 prefix is geographically allocated to the Mbadjini-Ouest region, with Foumbouni as its principal town. This area is characterized by its proximity to the island's interior highlands and its role as a local market hub. The code is not portable outside this designated geographic area, meaning that a number assigned to this prefix cannot be moved to another region without changing the NDC. This is a standard practice for geographic numbering in Comoros, ensuring that the prefix retains its locational significance.

Caller Instructions and Practical Considerations

For international callers, it is essential to replace the leading zero (if any) from the local format, as Comoros uses the +269 country code without a trunk prefix. For example, if a local number is listed as 779 1234, the international format would be +269 779 1234. Within Comoros, callers should always dial the full seven-digit number, including the NDC, even for calls within the same town. This is due to the country's small size and the need for unambiguous routing.

It is also worth noting that while mobile penetration in Comoros is high, fixed-line services remain limited and are primarily concentrated in urban and administrative centers. The 779 prefix is therefore a reliable indicator of a fixed-line connection in the Foumbouni area. For businesses or individuals seeking to establish a presence in this region, obtaining a number with this prefix can enhance local credibility and ensure that calls are routed efficiently within the national PSTN.
