Area Code 391 – Gaborone

Overview of Botswana's +267 391 Geographic Prefix

The +267 391 prefix is a geographic National Destination Code (NDC) assigned to the Gaborone metropolitan area, Botswana's capital and largest city. As part of the country's E.164 numbering plan, this code routes calls to fixed-line PSTN subscribers within the designated exchange areas of Gaborone, including central business districts, residential neighborhoods, and surrounding administrative zones. Unlike mobile or non-geographic services, 391 is tied to physical infrastructure, meaning the call terminates at a specific wireline address.

Coverage Area and Administrative Jurisdiction

Gaborone serves as the seat of government and the economic hub of Botswana. The 391 prefix covers the city's core exchanges, which include areas such as the Central Business District (CBD), Government Enclave, and nearby suburbs like Maruapula, Extension 2, and Village. These exchanges are managed by Botswana Telecommunications Corporation Limited (BTC), the incumbent fixed-line operator, which holds the geographic numbering resources for the country. The prefix is not used for mobile services; mobile numbers in Botswana are non-geographic and typically begin with 7 or 8.

Dialing Formats and Caller Instructions

For callers within Botswana, the national format requires dialing the trunk prefix '0' followed by the area code and subscriber number. For example, a local Gaborone number might be written as 0 391 234 567. When calling from abroad, the international format omits the leading '0' and adds the country code: +267 391 234 567. This format is essential for international callers, as omitting the '+' or using the national trunk prefix will result in a failed call. For local calls within Gaborone, callers may still need to dial the full national number, as Botswana has moved towards closed dialing for fixed lines; always confirm with your service provider.

Overlay and Numbering Considerations

Currently, there is no overlay code for Gaborone; the 391 prefix is unique to the city's fixed-line network. However, as demand for numbers grows, the Botswana Communications Regulatory Authority (BOCRA) may introduce additional geographic codes or overlay plans. For now, the 391 prefix remains a reliable indicator of a fixed-line connection in Gaborone. When porting numbers, users can retain their 391 number when switching between fixed-line operators, but the geographic significance remains tied to the original exchange.

Practical Tips for Businesses and Residents

Businesses in Gaborone often use 391 numbers to establish a local presence. For international clients, it is crucial to display the number in international format (+267 391 ...) on websites and marketing materials to avoid confusion. Additionally, when traveling abroad, ensure your service provider supports international dialing to Botswana, and be aware of potential charges for calling fixed lines versus mobile numbers. For VoIP users, the 391 prefix is treated as a geographic number, so emergency services and directory listings may be routed accordingly.
