📍 Geographic Location of Gamba
Overview of Gabon's Geographic Numbering Plan
Gabon's national telephone numbering plan adheres to the ITU-T E.164 recommendation, with a country calling code of +241. Geographic numbers are allocated to fixed-line services and are identified by a two-digit National Destination Code (NDC) that corresponds to a specific city or region. The NDC 0150 is assigned to Gamba, a coastal city located in the Ogooué-Maritime Province of southwestern Gabon. Gamba is a significant hub for the country's oil and gas industry, hosting major facilities operated by international energy companies. The geographic prefix 0150 is used for fixed-line telephony services within this area, providing connectivity for residential, commercial, and administrative users.
Dialing Formats and Usage
When calling a fixed-line number in Gamba from within Gabon, subscribers must dial the full national number, which includes the NDC and the subscriber's local number. The national format is 0150 XX XX XX, where the NDC '0150' is followed by a six-digit subscriber number. For example, a local call to a business in Gamba might be dialed as 0150 12 34 56. This format is used for all calls within Gabon, regardless of whether the caller is in the same city or a different region, as Gabon has implemented a closed dialing plan.
For international callers, the number must be dialed in the international format, which includes the country code and the NDC without the leading '0'. The international format is +241 150 XX XX XX. For instance, an international caller would dial +241 150 12 34 56 to reach the same number. The leading '0' of the NDC is only used for domestic calls and is omitted when dialing from abroad.
Regulatory and Technical Considerations
The allocation of geographic prefixes in Gabon is managed by the Autorité de Régulation des Communications Électroniques et des Postes (ARCEP), the national regulatory authority. The NDC 0150 is part of the public switched telephone network (PSTN) and is primarily used for traditional fixed-line services. However, with the evolution of telecommunications, some operators may offer voice over IP (VoIP) services that utilize geographic numbers, but the routing and numbering remain consistent with the national plan.
It is important to note that geographic numbers are not portable to mobile networks, as mobile services use separate non-geographic prefixes. When dialing from a mobile phone within Gabon, the same national format applies. For callers outside Gabon, it is essential to check with their service provider for international dialing rates and any restrictions that may apply to calls to fixed-line numbers in Africa.
