Area Code 3123 – Tarkwa

Overview of Tarkwa Geographic Area Code 3123

The area code 3123 is a geographic National Destination Code (NDC) assigned to the city of Tarkwa and its surrounding localities in the Western Region of Ghana. Tarkwa is a major mining hub, known for its gold and manganese extraction industries, and serves as the administrative capital of the Tarkwa-Nsuaem Municipal District. The code is part of the national numbering plan under the country calling code +233, adhering to ITU-T E.164 standards.

Geographic Coverage and Administrative Jurisdiction

The 3123 code covers Tarkwa and nearby towns such as Nsuaem, Abontiakoon, and other communities within the municipal district. It is used for fixed-line (PSTN) services, including traditional copper lines and some fixed wireless connections. The region is also home to the University of Mines and Technology (UMaT), which relies on this code for its administrative and academic communications.

Dialing Formats and Caller Instructions

For local callers within Ghana, the national dialing format is 03123 followed by the subscriber number. For example, to call a fixed line in Tarkwa with the number 456789, you would dial 03123456789 from anywhere in Ghana. International callers must use the full international format: +233 3123 456789 (or +2333123456789 when dialing without spaces). The leading zero of the NDC is dropped when adding the country code.

Overlay Considerations and Numbering Plan

Currently, there is no overlay code for the Tarkwa area; the 3123 code is exclusive to this geographic region. However, as Ghana's telecommunications sector evolves, the National Communications Authority (NCA) may introduce overlays or migrate fixed-line users to other technologies. Subscribers should be aware that number portability is not typically available for geographic fixed-line numbers within the same region, but changes are possible under NCA regulations.

Practical Usage and Economic Significance

Given Tarkwa's economic importance, the 3123 code is vital for mining companies, suppliers, and local businesses. It is also used by government offices and public services. For businesses, having a local geographic number enhances trust and accessibility for regional customers. For individuals, it provides a reliable connection to the community.

When dialing from abroad, ensure you have the correct international prefix (e.g., 00 or +) for your country. For example, from the UK, you would dial 00 233 3123 456789. Always confirm the subscriber number length, which typically ranges from 5 to 7 digits, making the total national significant number (NSN) 9 digits, as per Ghana's numbering plan.
