Area Code 3625 – Denu/Aflao

Overview of Area Code 3625

Area code 3625 is a geographic National Destination Code (NDC) assigned to the Denu and Aflao region in the Volta Region of Ghana. This code is part of the national numbering plan under the ITU-T E.164 standard, managed by the National Communications Authority (NCA) of Ghana. The region is located along the southeastern coast, bordering Togo, and includes the towns of Aflao, Denu, and surrounding communities. The code serves fixed-line PSTN subscribers within this specific geographic area.

Dialing Formats

To call a fixed-line number in the Denu/Aflao area, the full national number consists of the trunk prefix 0, the area code 3625, and the subscriber number, which typically has 5 to 6 digits. The complete national significant number (NSN) length is 9 digits (excluding the leading 0).

• Local dialing (within Ghana): Dial 03625 followed by the subscriber number. Example: 03625 12345.
• International dialing (from outside Ghana): Dial the international access prefix (e.g., 00 or +), then Ghana’s country code 233, then the area code without the leading 0 (3625), followed by the subscriber number. Example: +233 3625 12345.

Geographic Coverage and Administration

The 3625 code is administratively assigned to the Ketu South Municipal District, which includes the commercial hub of Aflao and the border town of Denu. This area is part of Ghana’s Volta Region and is a key transit point for trade with neighboring Togo. The code is used exclusively for fixed-line services, including traditional PSTN and some VoIP-based fixed lines that are registered with a physical address in the area. Mobile numbers in Ghana use separate non-geographic prefixes (e.g., 020, 024, 026, 027, 050, 054, 055, 057, 059) and are not affected by this code.

Caller Instructions

• Callers within Ghana: Always use the trunk prefix 0 before the area code when dialing from another region. For example, from Accra, dial 03625 12345.
• Callers from outside Ghana: Replace the leading 0 with the country code +233. Do not include the 0 when dialing internationally. For example, from the United States, dial 011 233 3625 12345.
• Overlay considerations: As of the latest NCA updates, there is no overlay code for this area; 3625 remains the sole geographic code for Denu/Aflao. However, the NCA periodically reviews numbering resources, so users should verify with their service provider if any changes occur.

Practical Usage

This area code is essential for businesses, government offices, and residents in the Denu/Aflao region. It is commonly used for landline services in hotels, banks, schools, and local enterprises. When storing contacts, it is advisable to include the international format (+233 3625 ...) to ensure reachability from abroad. For travelers, using a local SIM card with a mobile prefix is often more convenient, but for reaching fixed-line services such as customer support or government offices, knowing the correct dialing format for 3625 is crucial.
