Area Code 328 – Ashanti Region

Overview of Ghana Area Code 328

Area code 328 is a geographic National Destination Code (NDC) assigned to the Ashanti Region of Ghana, with its primary serving area centered on the city of Kumasi. As part of the national numbering plan under the National Communications Authority (NCA), this code is used for fixed-line (PSTN) services within the region. When dialing from abroad, the international format is +233 328 XXX XXX, while domestic callers within Ghana dial 0328 XXX XXX.

Geographic Coverage and Administrative Jurisdiction

The 328 code covers the Kumasi metropolitan area and surrounding districts within the Ashanti Region. This includes administrative and commercial hubs such as the Kumasi Central Business District, Asokwa, Suame, and Bantama. The code is assigned to fixed-line operators providing local loop services, and it is used for both residential and business lines. Unlike mobile prefixes, 328 is geographically tied to the Ashanti Region, meaning the number indicates the physical location of the line.

Dialing Formats and Caller Instructions

For local callers within Ghana, the national dialing format is 0328 XXX XXX. When calling from outside Ghana, you must use the international prefix (e.g., 00 or +) followed by the country code 233, then the area code without the leading zero: +233 328 XXX XXX. For example, a landline in Kumasi might be reached at +233 328 456 789. It is important to note that when dialing internationally, the trunk prefix '0' is omitted.

Overlay Considerations and Numbering Plan

As of the latest NCA updates, there is no overlay code for the Ashanti Region; 328 remains the sole geographic code for the Kumasi area. However, due to the growth of VoIP and mobile services, some businesses may use non-geographic numbers for customer service, but these are separate from the 328 code. Fixed-line numbers under 328 are not portable to mobile networks, and vice versa, due to the geographic nature of the code.

Practical Usage for Business and Personal Lines

Businesses operating in Kumasi often use 328 numbers to establish a local presence. For international callers, it is essential to check time zones (GMT) and to use the correct international dialing sequence. For domestic callers, note that calls to 328 numbers are charged at standard fixed-line rates, which may vary depending on the operator and time of day. Always confirm the number length: after the area code, subscriber numbers are typically 7 digits, resulting in a total of 10 digits for domestic dialing (including the trunk prefix).
