Area Code 27 – Savannah region

Geographic Overview

The +228 27 area code is a geographic National Destination Code (NDC) assigned to the Savannah region of Togo. This administrative region, known as Région des Savanes, is located in the northernmost part of the country and shares borders with Ghana to the west, Benin to the east, and Burkina Faso to the north. The primary city served by this code is Dapaong, the regional capital, along with surrounding towns and rural communities such as Mango, Tandjouaré, and Oti River settlements. The Savannah region is characterized by its semi-arid climate and agricultural economy, with a growing telecommunications infrastructure supporting local businesses, government services, and residential users.

Dialing Formats

When calling a landline in the Savannah region from within Togo, subscribers must dial the trunk prefix '0' followed by the area code and the subscriber number. For example, a local call to a number in Dapaong would be dialed as 027 12 34 56 (where '12 34 56' represents the six-digit subscriber number). From abroad, callers must use the international access prefix (e.g., '00' or '+'), followed by Togo's country code 228, the area code without the leading zero, and the subscriber number: +228 27 12 34 56. It is important to note that Togo's national numbering plan uses a closed dialing format for geographic numbers, meaning the area code must always be dialed, even for local calls within the same region.

Numbering and Overlay Considerations

The 27 code is part of Togo's geographic numbering plan, which allocates specific NDCs to each of the country's five regions. Currently, there is no overlay code in the Savannah region; the 27 code exclusively serves this area. However, as demand for fixed-line services evolves, the regulatory authority, ARTP (Autorité de Régulation des Secteurs de Télécommunications), may introduce additional codes or overlay plans. Subscribers in the Savannah region typically have six-digit subscriber numbers, resulting in a total national number length of eight digits (including the leading '0' for domestic calls).

Caller Instructions

For local callers within Togo, always include the trunk prefix '0' when dialing a Savannah number, even if you are calling from within the same region. For international callers, ensure you use the correct country code and omit the trunk prefix. For example, to call a business in Dapaong from the United States, you would dial: 011 228 27 12 34 56. From the UK, it would be 00 228 27 12 34 56. Always verify the subscriber number length, as some numbers may have been migrated or reassigned due to network changes.

Practical Usage

Geographic codes like 27 are primarily used for fixed-line PSTN services, though some VoIP providers may offer virtual numbers with this prefix. When contacting government offices, banks, or local enterprises in the Savannah region, expect to use this code. For travelers or businesses establishing a presence in northern Togo, obtaining a local number with the 27 code can enhance local trust and accessibility. Keep in mind that calls to geographic numbers are typically charged at standard national or international rates, depending on the caller's location and service provider.
