Area Code 25 – Central region

Geographic Coverage and Administrative Jurisdiction

The area code 25 is a geographic National Destination Code (NDC) assigned to the Central region of Togo. This region is administratively centered around the city of Sokodé, which serves as the principal urban hub and the capital of the Centrale Region. The code covers the prefectures of Tchaoudjo, Tchamba, and Sotouboua, encompassing both urban centers and surrounding rural communities. As a geographic code, it routes calls to fixed-line (PSTN) subscribers within this defined area, in accordance with the ITU-T E.164 numbering plan.

Dialing Formats and Caller Instructions

For international callers, the full number format is +228 25 XX XX XX, where +228 is the country calling code for Togo, followed by the two-digit area code 25 and the six-digit subscriber number. For example, a call to a fixed line in Sokodé would be dialed as +228 25 12 34 56.

Domestic callers within Togo must dial the full national number, including the area code, even when calling from a different region. The national format is 25 XX XX XX. For instance, a caller in Lomé would dial 25 12 34 56 to reach a subscriber in the Central region. It is important to note that Togo does not use trunk prefixes like '0' for domestic calls; the number is dialed as a continuous sequence of eight digits after the country code.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Central region; the 25 code is exclusively used for fixed-line services in this area. However, as Togo continues to expand its telecommunications infrastructure, the regulatory authority (ARTP) may introduce additional geographic codes or reallocate numbering resources. Fixed-line numbers under the 25 code are typically used by businesses, government offices, and residential subscribers, and are not portable to mobile networks due to the distinct numbering structure for mobile services (which begin with 90, 91, 92, 93, 96, 97, 98, or 99).

Practical Guidance for Callers

• Local callers within the Central region can dial the six-digit subscriber number directly, but it is safer to use the full national format to avoid misdialing.
• International callers should always use the plus sign (+) or the international access prefix of their country (e.g., 00) followed by 228 and the complete number.
• VoIP and mobile users should ensure they have international dialing enabled and correctly format the number to avoid routing errors.

Understanding the correct dialing procedure ensures efficient connectivity to businesses and residents in Togo's Central region, whether for commercial, governmental, or personal communication.
