📍 Geographic Location of Korhogo
Geographic Coverage and Administrative Context
The +225 2136 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network in Korhogo, the principal city of the Poro Region in northern Côte d’Ivoire. Korhogo serves as the administrative capital of the Savanes District and is a major economic hub for the cotton and mango industries. The numbering area encompasses the urban commune of Korhogo and its immediate suburbs, including the districts of Lataha, Niofoin, and Tioroniaradougou. Subscribers with this prefix are connected to the Ivorian PSTN and typically receive services from the incumbent operator (Côte d’Ivoire Telecom) or alternative fixed-line carriers that have been allocated local exchange capacity.
Dialing Formats and Usage
To call a Korhogo fixed-line number from within Côte d’Ivoire, dial the full national number: 21 36 XX XX (8 digits after the trunk prefix). For international callers, the format is +225 21 36 XX XX. The prefix 2136 is part of the national numbering plan under the +225 country code, which was implemented after the 2012 renumbering. Note that the leading '21' indicates the geographic zone for northern Côte d’Ivoire, while '36' identifies the Korhogo exchange. When calling from a mobile phone within the country, the same 8-digit number is used without any additional trunk prefix (the national trunk prefix '0' is not used in Côte d’Ivoire).
Overlay and Numbering Considerations
Currently, no overlay code has been introduced for Korhogo; the 2136 prefix remains dedicated to fixed-line services. However, as part of the West African Economic and Monetary Union (UEMOA) initiatives, Côte d’Ivoire has been expanding its fixed and mobile convergence. Some VoIP providers may route calls to 2136 numbers using IP-based interconnect, but the geographic nature of the prefix remains unchanged. For businesses, having a 2136 number establishes a local presence in Korhogo, which can be advantageous for customer trust and regional marketing. Callers from outside Côte d’Ivoire must always use the +225 country code, and should be aware that international tariffs apply. For local callers, calls to 2136 numbers are billed as local fixed-line calls, regardless of the caller’s own operator.
