Area Code 1158 – Lambaréné

Geographic Overview

The +241 1158 prefix is a geographic National Destination Code (NDC) assigned to the landline network serving the city of Lambaréné and its surrounding administrative area in Gabon. Lambaréné is the capital of Moyen-Ogooué Province, located in central-western Gabon along the Ogooué River. The code is used for fixed-line telephone services within this region, connecting residential, commercial, and governmental subscribers.

Dialing Formats

When calling a Lambaréné fixed-line number from within Gabon, the national trunk prefix '0' is dialed before the NDC and subscriber number. The full national format is 0 1158 XX XX, where '0' is the trunk prefix, '1158' is the geographic area code, and 'XX XX' represents the local subscriber number (typically 4 digits). For international callers, the country code +241 is used, and the leading '0' is omitted. The international format is +241 1158 XX XX. For example, a local call to a Lambaréné number would be dialed as 0 1158 12 34, while an international caller would dial +241 1158 12 34.

Calling Instructions

• Local callers (within Gabon): Dial 0 1158 XX XX from any fixed or mobile line.
• International callers: Dial the international access prefix (e.g., 00 from most countries), then Gabon's country code +241, followed by the NDC 1158 and the subscriber number. Do not include the trunk prefix '0'.
• Callers from other regions in Gabon: Use the national trunk prefix '0' before the NDC, as with local calls.

Regulatory and Technical Notes

Gabon's numbering plan is administered by the Autorité de Régulation des Communications Électroniques et des Postes (ARCEP). The 1158 prefix is part of the geographic numbering scheme, meaning that the number is tied to a physical location. However, with the advent of VoIP and number portability, subscribers may retain their numbers even if they move within the same geographic area, though the prefix still indicates the original service region. Fixed-line numbers in Gabon are typically used for PSTN services, but some operators may route calls over IP backbones. For emergency services or directory assistance, local numbers should be dialed in the national format.

When calling from a mobile phone within Gabon, it is common to dial the full national number including the trunk prefix '0'. International callers should always use the +241 country code to ensure proper routing. As with all geographic codes, the cost of calls to +241 1158 numbers is typically higher than local calls and depends on the caller's international tariff plan.
