📍 Geographic Location of Koulamoutou

Geographic Overview

The +241 0165 numbering block is a geographic allocation within the Gabonese national numbering plan, specifically designated for the city of Koulamoutou, the capital of Ogooué-Lolo Province in south-central Gabon. This area code serves the urban center and its surrounding administrative districts, including the Lolo River valley communities. As a geographic prefix, it is tied to the PSTN infrastructure of the region, historically operated by the incumbent operator Gabon Télécom, though the liberalization of the telecom market allows other licensed operators to provide fixed-line services using this range.

Dialing Formats

When calling a Koulamoutou fixed line from within Gabon, subscribers must dial the trunk prefix 0, followed by the area code 165 and the subscriber number. The complete national format is 0165 XX XX XX, resulting in a total of 9 digits after the trunk prefix. For international callers, the Gabonese country code +241 replaces the trunk prefix, and the area code loses its leading zero. Thus, the international dialing format becomes +241 165 XX XX XX. For example, a local call to a Koulamoutou number would be dialed as 0165 12 34 56, while an international caller would dial +241 165 12 34 56.

Caller Instructions

  • Local callers (within Gabon): Dial the full national number including the trunk prefix: 0165 XX XX XX.
  • International callers: Dial your country's exit code (e.g., 00 from most countries, 011 from the US/Canada), then 241, then the area code without the leading zero, and the subscriber number: +241 165 XX XX XX.
  • Mobile to fixed: Gabonese mobile users must also include the trunk prefix when calling fixed lines, so they would dial 0165 XX XX XX.

Overlay Considerations

As of the latest ITU-T E.164 national numbering plan updates, no overlay code has been introduced for Koulamoutou. The 0165 prefix remains the sole geographic code for the city. However, number portability may allow subscribers to retain their numbers when switching operators, but the geographic significance of the prefix remains unchanged. Callers should always verify the current dialing procedures with their service provider, as local dialing habits may vary in rural areas.
