Area Code 770 – Domoni

Overview of +269 770

The telephone country code +269 is assigned to the Union of the Comoros under the ITU-T E.164 international numbering plan. Within this national plan, the prefix 770 designates a geographic numbering area serving the town of Domoni, located on the island of Anjouan (Ndzuwani). Domoni is one of the principal settlements on the island and holds historical and administrative significance. The +269 770 prefix is used for fixed-line (PSTN) services within this locality.

Geographic Coverage and Administrative Jurisdiction

Domoni is situated on the eastern coast of Anjouan, one of the three semi-autonomous islands that constitute the Union of the Comoros. The prefix 770 covers the town and its immediate surrounding areas. Administratively, Domoni falls under the jurisdiction of the Anjouan regional government, which oversees local telecommunications infrastructure in coordination with the national regulatory authority. The numbering area is distinct from other Anjouan prefixes, such as 771 for Mutsamudu, ensuring efficient call routing and identification.

Dialing Formats

For callers within the Comoros, the national significant number (NSN) for Domoni is an eight-digit number beginning with 770. Local calls are placed by dialing the full NSN: 770 XX XX. For example, to reach a subscriber with the number 770 12 34, a caller within Comoros would dial 770 12 34.

For international callers, the correct format is the international prefix (typically + or 00), followed by the country code 269, and then the NSN without any leading zero. Thus, the same Domoni number would be dialed as +269 770 12 34. It is important to note that Comoros uses a closed numbering plan; there are no trunk prefixes or area codes to be dropped when dialing internationally.

Overlay and Numbering Plan Considerations

As of the latest ITU-T operational bulletins, there is no overlay code for the Domoni area. The 770 prefix is exclusively assigned to geographic fixed-line services in that region. However, the Comoros has been expanding its telecommunications infrastructure, and the regulatory authority may introduce additional prefixes or renumbering in the future. Subscribers in Domoni can typically keep their numbers when moving within the same exchange area, but porting to other geographic regions may require a change of prefix.

Caller Instructions

• Local callers (within Comoros): Dial the eight-digit number directly: 770 XX XX.
• International callers (outside Comoros): Dial your country's exit code (e.g., 00 or +), then 269, followed by the eight-digit number: +269 770 XX XX.
• Callers from mobile networks: The same dialing rules apply; no additional prefixes are required.

When calling from abroad, ensure that you have the correct international access code for your location. For example, from the United States or Canada, dial 011 269 770 XX XX; from most European countries, dial 00 269 770 XX XX.

Understanding the geographic significance of +269 770 helps both residents and international partners connect reliably with Domoni, a key hub on Anjouan.
