Area Code 117 – Libreville

Geographic Overview

The +241 117 prefix is a geographic National Destination Code (NDC) assigned to the Libreville area within the Republic of Gabon's national numbering plan, as administered by the Autorité de Régulation des Communications Électroniques et des Postes (ARCEP Gabon). Libreville, the capital and largest city of Gabon, is located in the Estuaire Province on the northwestern coast along the Gabon Estuary. This prefix serves both residential and business landline subscribers within the city's metropolitan area, including administrative, commercial, and diplomatic districts.

Dialing Formats

When placing a call to a number using the +241 117 prefix, the correct international format is +241 117 XX XX (or +241117XXXXX). The full national significant number (NSN) is 9 digits, beginning with the NDC '117' followed by a 6-digit subscriber number. For local calls within Gabon, callers must dial the full NSN including the leading '0' trunk prefix: 0 117 XX XX XX. Note that the international format omits the leading '0'.

Caller Instructions

• Callers from abroad: Dial the international access code (e.g., 00 from most countries), then Gabon's country code +241, followed by the NDC and subscriber number. Example: 00 241 117 12 34 56.
• Callers from within Gabon: Dial 0 117 12 34 56 (including the trunk prefix).
• International callers using a mobile phone: Simply enter +241 117 12 34 56 in the international format.

Overlay and Numbering Considerations

Gabon's numbering plan is closed, meaning the NDC is always dialed even for local calls. As of the latest ARCEP updates, the 117 prefix is a dedicated geographic code for Libreville, but due to increasing demand, overlay codes may be introduced in the future. Subscribers in Libreville may also be reached via mobile prefixes (e.g., 07x) if they have ported their number, but landline numbers beginning with 117 remain fixed to the geographic location.

Technical Notes

Landline numbers under +241 117 are primarily served by Gabon Telecom (the incumbent fixed-line operator) and other licensed fixed operators. These lines are connected via the PSTN and support standard voice, fax, and DSL services where available. International routing to this prefix is handled through Gabon's international gateway, and calls are subject to standard international tariffs. For VoIP users, it is essential to use the correct international format to ensure proper termination.
