Area Code 1150 – Gamba

Overview of Gabon Area Code 1150

Area code 1150 is a geographic destination code within the Gabonese national numbering plan, assigned to the city of Gamba and its surrounding administrative area. Gamba is a coastal town located in the Ogooué-Maritime Province of southwestern Gabon, known primarily for its role in the country's petroleum industry. The code is used for fixed-line (PSTN) services, and it is an integral part of the national dialing structure.

Dialing Format and Usage

When calling a fixed-line number in Gamba from within Gabon, subscribers must dial the national trunk prefix 0, followed by the area code 1150 and the subscriber's local number. For example, a local number might be dialed as 01150XXXXX from another region in Gabon. However, from within Gamba itself, local calls may often be made using only the subscriber number, depending on the operator's network configuration. For international callers, the Gabon country code +241 is used, followed by the area code without the leading trunk prefix. Thus, an international caller would dial +2411150XXXXX to reach a fixed line in Gamba.

Number Structure and Length

Gabonese fixed-line numbers, including those in Gamba, typically have a total length of 8 digits after the country code. The area code 1150 constitutes the first four digits of the national significant number, and the remaining four digits are the subscriber number. This structure is consistent with the ITU-T E.164 recommendation, ensuring global interoperability.

Geographic Coverage and Administrative Jurisdiction

The 1150 area code covers Gamba, which is the capital of the Ndougou Department in Ogooué-Maritime Province. The town is situated near the Atlantic coast and is a hub for oil and gas operations, with a significant expatriate community. The area code serves the town center and its immediate environs, including residential and commercial districts. It does not cover other cities in Gabon, which have their own distinct area codes.

Overlay and Numbering Considerations

As of the latest available information, there is no overlay plan for the 1150 area code. The Gabonese telecom regulator, ARCEP, has not announced any imminent changes to the numbering plan that would affect this code. However, with the ongoing migration to next-generation networks, some fixed-line services may be delivered over VoIP infrastructure, but the geographic significance of the code remains for routing and identification purposes.

Caller Instructions

For local callers within Gabon: To call a Gamba fixed line from another city, dial 0 followed by 1150 and the subscriber number. For callers from abroad: Dial the international access prefix (e.g., 00 or +), then 241, then 1150 and the subscriber number. Ensure you omit the initial '0' when dialing from outside Gabon.
