Area Code 775 – Moroni

Overview of +269 775 (Moroni Geographic Code)

The +269 775 prefix is a geographic National Destination Code (NDC) assigned to the capital city of Moroni, located on the island of Grande Comore (Ngazidja) in the Union of the Comoros. As a geographic code, it routes calls to fixed-line subscribers within the Moroni metropolitan area and its immediate surroundings. The Comorian numbering plan follows ITU-T E.164 recommendations, with a country calling code of +269 and subscriber numbers that are typically seven digits long. The prefix 775 forms the initial three digits of the seven-digit national significant number (NSN), meaning the complete number format is +269 775 XXXX.

Coverage and Administrative Jurisdiction

Moroni serves as the national capital and the largest city of the Comoros. The 775 code covers the urban zone of Moroni, including administrative districts such as Hamramba, Itsandra, and Mtsangamouji, as well as nearby localities within the Ngazidja island. The code is managed by the Comorian regulatory authority (Autorité de Régulation des Télécommunications des Comores, ARTC) and is allocated to fixed-line operators providing PSTN services in the region. As of the latest numbering plan updates, no overlay code has been introduced for Moroni, so 775 remains the sole geographic prefix for the capital.

Dialing Formats and Caller Instructions

For local callers within the Comoros, the national dialing format requires dialing the full seven-digit number, including the leading '7' of the prefix. For example, to reach a fixed line in Moroni, a local caller would dial 775 XXXX. International callers must use the international format: +269 775 XXXX (or 00269 775 XXXX from countries using the international prefix '00'). When calling from a mobile phone, the plus sign (+) is typically used. It is important to note that the Comoros uses a closed numbering plan; therefore, no trunk prefix (such as '0') is used for domestic calls. Callers from outside the Comoros should replace the '+' with the appropriate international access code (e.g., 011 from North America).

Technical Considerations for Fixed-Line Services

Subscriber numbers under the 775 prefix are allocated to traditional PSTN lines, which may also support ISDN and VoIP services provided by licensed operators. While the code is geographic, number portability is not yet fully implemented in the Comoros, so subscribers may not be able to retain their number when changing operators or relocating outside the Moroni area. For international calls, the Comorian network routes traffic via satellite and submarine cable links, ensuring connectivity with global carriers. Callers should verify time zone differences (UTC+3) and potential peak-hour tariffs when placing international calls.
