Overview of Ghana Area Code 3720

Area code 3720 is a geographic National Destination Code (NDC) assigned to the city of Tamale, the capital of Ghana’s Northern Region. In the international E.164 format, the full number is written as +233 3720 XXX XXX, where the leading trunk prefix '0' is dropped when dialing from abroad. Within Ghana, callers dial 03720 followed by the subscriber number, making the total national significant number (NSN) length 10 digits (including the trunk prefix).

Geographic Coverage and Administrative Jurisdiction

The 3720 code serves the Tamale Metropolitan District and its immediate environs, including surrounding communities such as Sagnarigu, Mion, and Tolon. As a geographic code, it is tied to the physical PSTN infrastructure of the region, though modern networks may route calls over IP backbones. Tamale is a major commercial and administrative hub in northern Ghana, and the code is used by both residential and business landlines.

Dialing Procedures

Local callers (within Ghana): Dial 03720 followed by the 7-digit subscriber number. Example: 03720 123456.
International callers: Dial the international access prefix (e.g., 00 from most countries), then 233, then 3720, and the 7-digit subscriber number. Example: +233 3720 123456.
Mobile to landline: Mobile users in Ghana must include the trunk prefix '0' when dialing a landline, i.e., 03720 123456.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for Tamale; 3720 remains the sole geographic code for the area. However, number portability is implemented in Ghana, allowing subscribers to retain their numbers when switching between fixed-line operators. This means that a number with the 3720 prefix may not necessarily be served by the original incumbent operator, but the geographic association remains unchanged.

Practical Guidance for Callers

For businesses and individuals calling Tamale from abroad, it is essential to omit the leading '0' of the area code and to use the full international format. For example, a caller from the United States would dial 011 233 3720 123456. Always verify the subscriber number length, as it is fixed at 7 digits for this NDC. If you experience routing issues, confirm that you are using the correct country code and that your service provider supports calls to Ghanaian geographic numbers.

❓ Frequently Asked Questions

What is the international dialing format for a Tamale landline with area code 3720?

To call a Tamale landline from abroad, dial your country's international access prefix (e.g., 00 or 011), then Ghana's country code 233, then the area code 3720 without the leading '0', followed by the 7-digit subscriber number. For example: +233 3720 123456.

Do I need to dial the '0' when calling a Tamale number from a Ghanaian mobile phone?

Yes, when calling from a mobile phone within Ghana, you must include the trunk prefix '0' before the area code. So you would dial 03720 followed by the subscriber number, e.g., 03720 123456.

Is area code 3720 only for landlines, or can it be used for mobile numbers?

Area code 3720 is a geographic code designated for fixed-line services in Tamale. Mobile numbers in Ghana use non-geographic prefixes (e.g., 02x, 05x). However, due to number portability, a fixed-line number with 3720 could theoretically be ported to a mobile network, but it would remain a fixed-line number in terms of dialing format.

Are there any overlay codes for Tamale?

As of the current numbering plan, there is no overlay code for Tamale. The 3720 code is the sole geographic area code for the city. If additional numbering capacity is needed in the future, an overlay could be introduced, but none exists today.

How many digits are in a complete Tamale landline number?

A complete national number (including the trunk prefix '0') is 10 digits: 0 + 3720 (4 digits) + 7-digit subscriber number. In international format, it is 12 digits including the country code: +233 3720 XXX XXX.
