Overview of Area Code 1154
Area code 1154 is a geographic National Destination Code (NDC) assigned to the city of Omboué, the capital of the Ogooué-Maritime Province in western Gabon. This code is part of the national numbering plan administered by the Agence de Régulation des Télécommunications (ARTEL), following ITU-T E.164 recommendations. Omboué is a coastal town located on the Ndogo Lagoon, serving as an important administrative and economic hub for the region.
Dialing Formats
When calling a landline in Omboué from within Gabon, subscribers must dial the trunk prefix 0 followed by the NDC and the subscriber number. The national format is:
- 0 1154 XX XX (for local calls within Gabon)
For international callers, the country code +241 replaces the leading zero. The international format is:
- +241 1154 XX XX
For example, a local call to a business in Omboué would be dialed as 01154XXXX, while an international caller would dial +2411154XXXX.
Geographic Coverage and Administration
The 1154 prefix serves the urban and suburban areas of Omboué, including the surrounding administrative districts. It is a fixed-line service primarily provided by Gabon Telecom, the incumbent operator, though alternative carriers may offer services in the region. The code is geographically significant, as it identifies the caller's location for billing and emergency services purposes.
Caller Instructions
Local callers within Gabon must always include the trunk prefix 0 when dialing any number outside their local area. For example, a caller in Libreville (area code 1174) would dial 01154XXXX to reach Omboué. International callers should replace the leading zero with the +241 country code. It is important to note that Gabon's numbering plan does not currently use area code overlays; each geographic region has a unique NDC.
Regulatory and Technical Notes
As with all geographic codes in Gabon, the 1154 prefix is subject to number portability regulations, allowing subscribers to retain their numbers when changing operators within the same geographic area. The code is not used for mobile services, which are assigned separate non-geographic prefixes. For accurate billing and routing, ensure that the correct number of digits is dialed, as Gabon's national numbering plan uses a fixed-length format of 8 digits (including the NDC) for all geographic numbers.
