Area Code 1148 – Libreville

Geographic Overview

The +241 1148 prefix is a geographic National Destination Code (NDC) assigned to the Libreville area, the capital and largest city of Gabon. This code is part of the country's public switched telephone network (PSTN) and is used for fixed-line services within the city and its immediate suburbs. Libreville is the administrative, economic, and political hub of Gabon, hosting the presidential palace, government ministries, and the headquarters of major national and international companies. As such, numbers under this prefix are commonly associated with businesses, government offices, and residential landlines in the capital.

Dialing Formats

When calling a number with the 1148 prefix, the format depends on the caller's location:

• International call from abroad: Dial +241 1148 XXX XX (or the full national number after the country code). For example, +241 1148 12 34 56.
• Domestic call within Gabon: Dial 1148 XXX XX (the full national number, including the NDC). For instance, 1148 12 34 56.
• Local call within Libreville (if no overlay): In some cases, local calls may be made using only the subscriber number (XXX XX), but it is recommended to always use the full national number to avoid confusion, especially with mobile and VoIP services.

Note that Gabon's numbering plan uses a closed format: the national significant number (NSN) is 8 digits for fixed lines, starting with the NDC '11' followed by a two-digit geographic area code (e.g., 48 for Libreville) and a six-digit subscriber number. The international format is +241 1148 XXXXXX.

Jurisdiction and Coverage

The 1148 prefix is administered by the telecommunications regulatory authority of Gabon (ARCEP) and is allocated to the incumbent operator, Gabon Telecom, which provides fixed-line services in the Libreville area. The coverage area includes the city center, residential districts like Oloumi, Nzeng-Ayong, and the industrial zone of Owendo. It is important to note that this prefix is geographic; the number is tied to a physical location, and the subscriber's address determines the applicable local tariffs.

Caller Instructions

For callers within Gabon, dialing a 1148 number from a mobile or another fixed line requires the full national number. For international callers, always use the country code +241, then the NDC and subscriber number. Do not omit the leading '1' of the NDC when dialing internationally. If you are experiencing difficulties, verify that you have the correct number of digits and that the number has not been ported to a different operator (number portability is available in Gabon, but geographic numbers usually retain their original prefix).

Overlays and Future Considerations

Currently, there is no overlay code for Libreville; the 1148 prefix is unique for fixed lines in the capital. However, as Gabon expands its telecommunications infrastructure, new geographic codes may be introduced. Always check the latest numbering plan updates from ARCEP if you are setting up services or integrating telecom systems.
