Area Code 3031 – Boké

Overview of Guinea Area Code 3031

Area code 3031 is a geographic destination code assigned within the Republic of Guinea's national numbering plan, under the international country calling code +224. This code corresponds to the Boké Region, an administrative area in northwestern Guinea that borders Guinea-Bissau and Senegal. The region is known for its bauxite mining operations and includes the city of Boké, the regional capital, as well as the prefectures of Boffa, Fria, Gaoual, and Koundara.

Dialing Formats

When calling a fixed-line number in the Boké Region from within Guinea, subscribers must dial the trunk prefix 0, followed by the area code 3031 and the subscriber's local number (typically 6 digits). For example, a local call to a number in Boké would be dialed as 030 31 XX XX XX (where X represents the subscriber digits). From abroad, callers must use the international prefix (e.g., 00 or +), then the country code 224, followed by the area code without the leading zero: +224 3031 XX XX XX. It is essential to omit the trunk prefix '0' when dialing from outside Guinea.

Geographic Coverage and Administrative Jurisdiction

The 3031 area code serves the entire Boké Region, which is one of Guinea's eight administrative regions. The region's economy is heavily reliant on mining, particularly bauxite, and agriculture. The code covers both urban and rural fixed-line subscribers within the region, including businesses, government offices, and residential lines. As a geographic code, it is tied to the physical location of the exchange, and calls are routed based on the destination's location.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Boké Region; the 3031 code is the sole geographic code for the area. However, the National Regulatory Authority (ART) may introduce additional codes in the future to meet demand. Subscribers should note that while mobile numbers in Guinea are non-geographic and begin with 6, fixed-line numbers like those under 3031 are geographic and cannot be ported to other regions.

Caller Instructions

For local callers within Guinea: dial 030 31 XX XX XX. For international callers: dial your country's exit code (e.g., 011 from the US, 00 from most European countries), then 224 3031 XX XX XX. Ensure you have the correct subscriber number, as omitting digits will result in a failed call. Charges for international calls to Guinea vary by carrier, and calls to geographic numbers are typically billed at standard international rates.
