Area Code 5735 – Farafenni

Overview of Gambia's Geographic Numbering Plan

The Republic of The Gambia, assigned the ITU-T E.164 country calling code +220, employs a fully integrated numbering plan without trunk prefixes. All national significant numbers (NSN) are seven digits long. Geographic numbers are identified by their first two digits, which constitute the National Destination Code (NDC). The prefix 5735 is a geographic NDC allocated to the Farafenni area, located in the North Bank Division along the Trans-Gambia Highway.

Geographic Coverage and Administrative Jurisdiction

Farafenni serves as the principal urban center of the North Bank Division, bordering the Gambia River. The 5735 prefix covers the town itself and surrounding settlements within the Lower and Upper Nuimi districts. As a geographic allocation, this prefix is tied to the PSTN infrastructure of fixed-line operators, primarily Gamtel, the national incumbent. The numbering area is distinct from mobile prefixes (e.g., 7xx, 9xx) which are non-geographic and portable across the country.

Dialing Formats and Caller Instructions

For international callers, the full number must be dialed in the format +220 5735 XXXX, where XXXX is the four-digit subscriber line number. No trunk prefix (such as '0') is used in The Gambia. For example, to call a fixed line in Farafenni from abroad, one would dial +220 5735 1234. Local callers within The Gambia simply dial the seven-digit number: 5735 1234. This applies regardless of whether the caller is using a fixed or mobile phone.

Numbering and Overlay Considerations

Currently, there is no overlay plan for the Farafenni area; the 5735 prefix is exclusive to its geographic region. However, number portability is not yet implemented for fixed-line services in The Gambia, meaning that if a subscriber relocates outside the Farafenni exchange area, they would typically be assigned a new number with the appropriate local prefix. The Public Switched Telephone Network (PSTN) infrastructure remains the primary bearer for these lines, though VoIP gateways may interconnect with the national network.

Practical Usage and Reliability

For businesses and residents in Farafenni, the 5735 prefix is essential for establishing a local presence. When dialing from a mobile phone within The Gambia, the call is treated as a national call, and standard rates apply. International callers should be aware that Gambian fixed-line numbers are often less reachable during peak hours due to limited international gateway capacity. It is advisable to use the +220 country code and the full number without any leading zeros.
