📍 Geographic Location of Port-Gentil

Geographic Overview

The +241 1155 prefix is a geographic National Destination Code (NDC) assigned to the Port-Gentil area in Gabon. Port-Gentil, the country's second-largest city and principal economic hub, is located on the Ogooué River delta and serves as the center of Gabon's oil and gas industry. This prefix is used for fixed-line telephone services within the Port-Gentil exchange area, which includes the city itself and its immediate suburbs.

Dialing Formats

When calling a number with the 1155 prefix, the dialing format depends on the caller's location:

  • International format: +241 1155 XXX XX (or +2411155XXXXX for the full national number). For example, a local number might be formatted as +241 1155 12345.
  • National format (within Gabon): 1155 XXX XX (or 1155XXXXX). Callers from other regions in Gabon must dial the full national number, including the NDC.
  • Local format (within Port-Gentil): In some cases, local calls may be dialed without the NDC, but due to number length and overlay considerations, it is recommended to always use the full national number to avoid misdialing.

Caller Instructions

For international callers: Dial your country's international access code (e.g., 00 or +), then Gabon's country code 241, followed by the NDC 1155 and the subscriber's number. For example, to call a number in Port-Gentil, you would dial +241 1155 XXXXX.

For local callers within Gabon: Dial the full national number: 1155 XXXXX. If you are in the same local area, you might be able to dial just the subscriber number, but this is not guaranteed due to the implementation of closed numbering plans. Always check with your service provider.

Administrative and Technical Notes

The 1155 prefix is part of the Gabonese national numbering plan, which follows ITU-T E.164 recommendations. Fixed-line numbers in Gabon are typically 8 digits long (including the NDC) when dialed nationally. The 1155 NDC is allocated to the geographic region of Port-Gentil, and its use is restricted to fixed-line services. Mobile numbers in Gabon start with different prefixes (e.g., 06, 07) and are non-geographic.

There are no overlay codes for Port-Gentil at present, meaning that the 1155 prefix is unique to this area. However, as the telecommunications market evolves, the regulator (ARCEP Gabon) may introduce additional NDCs or overlay plans to meet demand. For now, callers should continue to use the 1155 prefix for all fixed-line numbers in Port-Gentil.
