Area Code 310 – Gaborone

Overview of Botswana Area Code 310

Area code 310 is a geographic National Destination Code (NDC) assigned to the outer districts of Gaborone, the capital city of Botswana. It is part of the national numbering plan administered under ITU-T E.164, with the full international dialing prefix +267 310. This code serves the metropolitan fringe areas beyond the central business district, including residential suburbs, industrial zones, and satellite communities that rely on the capital's infrastructure.

Geographic Coverage and Administrative Jurisdiction

The 310 prefix covers the Gaborone outer ring, which includes neighborhoods such as Block 7, Block 8, Broadhurst Industrial, Gaborone West, and Tlokweng (though Tlokweng has its own separate codes). Administratively, these areas fall under the Gaborone City Council and the surrounding South-East District. The code serves both residential and commercial customers, with a mix of fixed-line PSTN and VoIP services.

Dialing Formats and Caller Instructions

For callers within Botswana, the national format is 310 XXXXX (7 digits total after the trunk prefix). For international callers, the format is +267 310 XXXXX. When dialing from a mobile phone within Botswana, it is common to use the full national number without the leading trunk prefix, e.g., 310 12345.

• Local call (within Botswana): Dial 310 12345 (if using a landline, you may need to prefix with 0 depending on the operator, but Botswana uses a closed numbering plan; the trunk prefix is not required for mobile-to-fixed calls).
• International call (from abroad): Dial your country's exit code, then 267 310 12345.

Overlay and Numbering Considerations

Botswana does not currently use overlay codes for geographic areas; each geographic region has a distinct NDC. However, number portability allows subscribers to retain their 310 numbers when moving to other operators, but the geographic significance remains tied to the original assignment. As of 2025, there are no plans to introduce an overlay for the Gaborone area, but the Botswana Communications Regulatory Authority (BOCRA) periodically reviews numbering resources.

Practical Usage and Business Impact

Businesses in the outer Gaborone areas use 310 numbers to establish a local presence. For international clients, dialing +267 310 is straightforward. For VoIP users, ensure that your provider supports termination to Botswana geographic numbers, as some may route calls via IP with varying quality. Always verify the current dialing procedures with your telecom operator, as local dialing habits may evolve.
