Area Code 3421 – Nsawam

Geographic Overview

The +233 3421 numbering block is a geographic National Destination Code (NDC) assigned to the Nsawam area within the Eastern Region of Ghana. Nsawam is a significant commercial hub located approximately 36 kilometers northwest of Accra, serving as a major transit point on the Accra–Kumasi highway. The code covers the Nsawam-Adoagyiri Municipal District, including the towns of Nsawam, Adoagyiri, and surrounding communities. This prefix is used for fixed-line (PSTN) services, and numbers under this code are typically 8 digits long when dialed locally (excluding the trunk prefix).

Dialing Formats

For callers within Ghana, the national dialing format requires the trunk prefix 0 followed by the area code and subscriber number: 0 3421 XXX XXX. For international callers, the country code +233 replaces the leading zero, resulting in the format +233 3421 XXX XXX. For example, a local call to a Nsawam number would be dialed as 03421 123 456, while an international caller would dial +233 3421 123 456.

Geographic Coverage and Administration

The Nsawam exchange serves both residential and business customers within the municipal district. It is administered by the National Communications Authority (NCA) of Ghana, which oversees the allocation and management of numbering resources. As a geographic code, the prefix is tied to a specific physical location, and calls to these numbers are routed via the traditional PSTN infrastructure. However, with the evolution of telecommunications, some services may be delivered over VoIP backbones, but the number remains associated with the Nsawam area for regulatory and routing purposes.

Caller Instructions

• Local callers (within Ghana): Dial 03421 XXX XXX (including the trunk prefix 0).
• International callers: Dial your country's exit code (e.g., 00 or +), then 233 3421 XXX XXX (omit the leading 0).
• Roaming or mobile callers: When calling a fixed line in Nsawam from a mobile phone in Ghana, the same national format applies: 03421 XXX XXX.

Overlay and Numbering Considerations

As of the latest NCA numbering plan, there is no overlay code for the Nsawam area; the 3421 code is unique to this region. Subscriber numbers under this code are typically 7 digits long, making the total national significant number (NSN) 9 digits (including the leading 0). The NCA periodically reviews numbering resources, but no changes are currently anticipated for this area. For accurate billing and routing, always verify the number length and format with your service provider.
