Area Code 773 – Moroni

Geographic Overview

The +269 773 prefix is a geographic National Destination Code (NDC) assigned to the Moroni area, the capital city of the Union of the Comoros, located on the island of Grande Comore (Ngazidja). Moroni serves as the country's political, economic, and administrative hub, housing government institutions, international embassies, and the main seaport. The prefix covers the urban and peri-urban zones of Moroni, including neighborhoods such as Itsandra, Mvouni, and Ikoni, as well as surrounding localities within the Moroni district.

Dialing Formats

When calling a landline in Moroni from within Comoros, subscribers must dial the full national number, which includes the NDC and the subscriber number. The national dialing format is 773 XX XX (seven digits in total). For international callers, the Comorian country code +269 is required, followed by the NDC and subscriber number, without any trunk prefix. The international format is +269 773 XX XX. Note that Comoros uses a closed numbering plan; there is no trunk prefix (such as a leading zero) used in either national or international dialing.

Caller Instructions

Local callers within Comoros should dial the seven-digit number directly: 773 XX XX. International callers should dial their country's international exit code (e.g., 011 from the US, 00 from most European countries), followed by Comoros country code 269, then the seven-digit number: +269 773 XX XX. For example, a call to a Moroni landline might be dialed as +269 773 12 34 from abroad.

Technical and Regulatory Notes

Geographic numbers in Comoros are allocated by the national regulatory authority, the Autorité Nationale de Régulation des TIC (ANRTIC). The 773 prefix is specifically designated for fixed-line services in the Moroni area. As of the latest ITU-T E.164 national numbering plan, Comoros does not currently have any overlay codes for Moroni; the 773 code remains the sole geographic NDC for the capital region. Subscriber numbers under this prefix are typically six digits long, following the NDC. While fixed-line services are primarily delivered over the PSTN, some operators may use VoIP technology for backhaul, but the numbering remains geographically tied to Moroni for regulatory and emergency service routing purposes.

For businesses or individuals seeking a local presence in Moroni, obtaining a number with the 773 prefix can enhance local credibility and ensure reachability via traditional landline networks. However, due to the limited fixed-line infrastructure in the Comoros, many residents and businesses rely on mobile services, which use separate non-geographic prefixes. When dialing from abroad, callers should be aware of potential network congestion and ensure they have the correct international dialing prefix for their location.
