Area Code 357 – Brong-Ahafo Region

Overview of Ghana Area Code 357

Area code 357 is a geographic National Destination Code (NDC) assigned to the Brong-Ahafo Region of Ghana, in accordance with the ITU-T E.164 international numbering plan. This region, known for its agricultural output and growing urban centers, uses this code for fixed-line (PSTN) services. The code is used when dialing landline numbers within the region from anywhere in the world.

Geographic Coverage and Administrative Jurisdiction

The Brong-Ahafo Region is one of Ghana's administrative regions, and its capital is Sunyani. The area code 357 covers the entire region, including major towns such as Techiman, Berekum, Dormaa Ahenkro, and Wenchi. The region is bordered by the Ivory Coast to the west and several other Ghanaian regions, making it a key inland hub.

Dialing Formats and Instructions

To call a fixed-line number in the Brong-Ahafo Region, the full international format is: +233 357 XXX XXX (where X represents the subscriber's local number digits). The national trunk prefix is 0, so domestic callers within Ghana must dial 0357 XXX XXX.

• Local callers (within Ghana): Dial the trunk prefix '0' followed by the area code and subscriber number: 0357 XXX XXX.
• International callers: Dial the country code +233, then the area code without the leading '0', followed by the subscriber number: +233 357 XXX XXX.

For example, a fixed-line number in Sunyani might be +233 357 123 456. When calling from abroad, you would dial +233 357 123 456.

Overlay and Numbering Considerations

As of the latest numbering plan updates, there is no overlay code for the Brong-Ahafo Region; the 357 code is exclusively used for geographic fixed-line services. However, due to the growth of mobile and VoIP services, some businesses may use non-geographic numbers, but these are not assigned under 357. The number length for fixed lines in Ghana is typically 9 digits after the country code (including the NDC), so the subscriber number is 7 digits long.

Caller Instructions

For local callers: Always include the trunk prefix '0' when dialing within Ghana. For international callers: Do not include the '0' after the country code. Ensure you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from the US/Canada) before dialing +233 357...

If you are unsure about the correct number, verify with the recipient or a local directory. Fixed-line numbers in this region are primarily used by businesses, government offices, and residential landlines.
