Area Code 3520 – Sunyani

Geographic Overview

The area code 3520 is a geographic National Destination Code (NDC) assigned to the city of Sunyani, the capital of the Bono Region in Ghana. Sunyani serves as a major administrative, commercial, and educational hub, hosting institutions such as the University of Energy and Natural Resources. The code covers the Sunyani Municipality and its immediate environs, including surrounding towns and communities within the metropolitan area.

Dialing Formats

When calling a Sunyani landline from within Ghana, subscribers dial the trunk prefix 0, followed by the area code 3520 and the subscriber number. The complete national format is: 0 3520 XXX XXX (10 digits after the trunk prefix). For example, a local Sunyani number might be dialed as 03520 123 456.

For international callers, the country code for Ghana is +233. The leading trunk prefix 0 is omitted. Therefore, the international dialing format becomes: +233 3520 XXX XXX. For instance, the same number would be dialed as +233 3520 123 456 from abroad.

Caller Instructions

• Local callers (within Sunyani): Although local calls may be dialed using only the subscriber number in some legacy networks, the recommended and most reliable method is to dial the full national format: 03520 XXX XXX.
• Domestic callers (from other regions in Ghana): Dial the full national format: 03520 XXX XXX.
• International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 233, then 3520, followed by the subscriber number. Do not include the leading 0.

Numbering Plan Considerations

Ghana's numbering plan follows ITU-T E.164 recommendations. Geographic area codes are assigned by the National Communications Authority (NCA). As of the current plan, Sunyani's code 3520 is part of the 03 series used for fixed-line services in the northern and middle belts of Ghana. There are no overlay codes currently in effect for Sunyani; the 3520 code is exclusive to the geographic region. Subscriber numbers within this code are typically 7 digits long, making the total national significant number (NSN) 9 digits (including the area code but excluding the trunk prefix).

When dialing from abroad, it is essential to use the correct international prefix for your country and to ensure that the number is entered without any leading zeros. For example, a call from the UK to Sunyani would be: 00 233 3520 XXX XXX.

Always verify the current numbering plan with your telecom provider, as number portability and reallocations may occasionally affect specific ranges.
