Area Code 763 – Moroni

Overview of +269 763

The +269 763 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 part of the Comorian numbering plan, this prefix routes calls to fixed-line subscribers within the Moroni metropolitan area and its immediate surroundings. The country code +269 is used for all international calls to Comoros, and the national significant number (NSN) is typically seven digits in length, with the NDC (763) followed by a four-digit subscriber number.

Geographic Coverage and Administrative Jurisdiction

Moroni serves as the political and administrative capital of the Union of the Comoros. The 763 prefix covers the urban zone of Moroni, including the central business district, government buildings, and residential areas. It also extends to nearby localities such as Itsandra and Ikoni, which are part of the greater Moroni area. As a geographic code, it is tied to the physical location of the subscriber's line, and calls to this prefix are routed via the fixed PSTN infrastructure.

Dialing Formats and Caller Instructions

For local callers within Comoros, dialing a number in the 763 prefix requires only the seven-digit NSN, e.g., 763 1234. For international callers, the full international format must be used: +269 763 1234 (or 00269 763 1234 from countries using the international dialing prefix 00). When calling from a mobile phone, the plus sign (+) is typically used to denote the international access code. It is important to note that Comoros does not use trunk prefixes like '0' for domestic long-distance calls; the NDC is always included in the national dialing.

Overlay and Numbering Considerations

As of the latest ITU-T recommendations, Comoros has not implemented overlay codes for geographic areas. The numbering plan is closed, meaning that the NDC is always dialed even for local calls. This simplifies dialing procedures and ensures that each subscriber number is unique nationwide. The 763 prefix is exclusively for fixed-line services, and mobile numbers are assigned separate non-geographic prefixes (e.g., 3xx, 4xx, 5xx, 6xx, 7xx, 8xx, 9xx) depending on the operator. Therefore, a number starting with 763 will always be a fixed line in Moroni.

Practical Examples for Callers

• Local call (within Comoros): 763 5678
• International call (from abroad): +269 763 5678
• Alternative international format: 00269 763 5678

When dialing from a country that uses the international access code '011' (e.g., North America), the format would be 011 269 763 5678. Always verify the current dialing instructions with your telecom provider, as international dialing prefixes vary by country.
