Dialing Formats and Instructions
- Local callers (within Comoros): Dial the seven-digit national number directly. For example, to reach a landline in Mutsamudu, dial 771 XXXX (where XXXX is the subscriber's four-digit line number). No trunk prefix is required.
- International callers: Dial the international access prefix (00 or +), followed by the Comoros country code 269, then the seven-digit national number. For instance, to call a number in Mutsamudu from abroad, dial +269 771 XXXX.
Numbering Plan and Overlay Considerations
Comoros employs a closed numbering plan for geographic numbers, meaning the NDC (771) is always dialed, even for local calls. There are no overlay codes currently in effect for Mutsamudu; the prefix 771 remains the sole geographic identifier for the city. Subscriber numbers under this prefix are four digits long, making the total national significant number (NSN) seven digits. This format is consistent across all geographic and mobile codes in the country.
Caller Guidance
For local callers within Comoros, it is essential to include the 771 prefix even when calling from another landline in the same city. For international callers, always replace the leading zero (if any) with the +269 country code. Ensure you have the correct seven-digit number, as omitting the prefix will result in a failed call. Mobile callers within Comoros can dial the same seven-digit format without any additional codes.
