Area Code 778 – Mitsamiouli

Geographic Overview

The +269 778 prefix is a geographic National Destination Code (NDC) assigned to the Mitsamiouli area, located on the island of Grande Comore (Ngazidja) in the Union of the Comoros. Mitsamiouli is a coastal town in the northwest of the island, known for its beaches and as a gateway to the Mitsamiouli-Douhani region. This prefix is used for fixed-line (PSTN) services within the local exchange area.

Dialing Formats

When calling a Mitsamiouli number from within Comoros, subscribers must dial the trunk prefix 0 followed by the NDC and the subscriber number. The national significant number (NSN) for geographic numbers in Comoros is typically 7 digits, with the NDC being 3 digits (e.g., 778) and the subscriber number being 4 digits. The complete national dialing format is: 0 778 XXXX.

For international callers, the Comoros country code is +269. The international format requires dropping the leading trunk prefix '0'. Therefore, to call a Mitsamiouli number from abroad, you would dial: +269 778 XXXX. For example, if the local subscriber number is 1234, the full international number would be +269 778 1234.

Caller Instructions

• Local callers (within Comoros): Dial the full national number including the trunk prefix: 0778 XXXX (if the subscriber number is 4 digits) or as per the local 7-digit format. Always include the '0' before the NDC when dialing from a different region or a mobile phone.
• International callers: Dial your country's international access code (e.g., 00 or +), then the Comoros country code 269, followed by the NDC and subscriber number without the leading '0': +269 778 XXXX.

Numbering Plan Considerations

Comoros operates under ITU-T E.164 standards. The country code +269 is shared by all islands of the Union. Geographic prefixes like 778 are allocated to specific fixed-line exchanges, and numbers are not portable across different geographic areas. However, mobile numbers in Comoros are non-geographic and begin with different prefixes (e.g., 3, 4, 5, 9). As of the latest ITU operational bulletin, no overlay code has been assigned for Mitsamiouli; the 778 prefix remains dedicated to that exchange.

For businesses or individuals in Mitsamiouli, having a local number with the 778 prefix helps establish a local presence and reduces long-distance charges for customers within the area. When dialing from abroad, be mindful of time zone differences (UTC+3) and potential network congestion during peak hours.
