Area Code 315 – Gaborone

Overview of Botswana Area Code 315

Area code 315 is a geographic National Destination Code (NDC) assigned to the capital city of Botswana, Gaborone, and its immediate surrounding areas. It operates within the framework of the ITU-T E.164 international numbering plan, under the country calling code +267. Botswana does not use trunk prefixes; therefore, the full national significant number (NSN) for a fixed-line subscriber in Gaborone consists of the three-digit area code followed by a five-digit subscriber number, yielding a total of eight digits (e.g., 315 XX XXX).

Geographic Coverage and Administrative Jurisdiction

The 315 code covers the Gaborone metropolitan area, which serves as the political and administrative capital of Botswana. This includes key districts such as the Central Business District, Broadhurst, Gaborone West, and Tlokweng, as well as nearby villages within the greater Gaborone agglomeration. The code is managed by the Botswana Communications Regulatory Authority (BOCRA) and is allocated to fixed-line services, primarily provided by Botswana Telecommunications Corporation Limited (BTCL) and licensed alternative operators.

Dialing Formats and Caller Instructions

Local callers (within Botswana): To call a fixed line in Gaborone from elsewhere in Botswana, dial the full eight-digit national number: 315 XX XXX. No trunk prefix (such as '0') is required.

International callers: When calling from abroad, dial the international access prefix (e.g., 00 or +), followed by Botswana's country code 267, and then the eight-digit national number: +267 315 XX XXX. Do not add any leading zero.

Example: If the subscriber number is 45 123, a local call would be dialed as 315 45 123, and an international call would be dialed as +267 315 45 123.

Overlay and Numbering Considerations

Currently, there is no overlay code for Gaborone; the 315 code remains exclusive to the region. However, due to increasing demand, BOCRA has implemented number expansion strategies, and some new fixed-line connections may receive numbers under other geographic codes if capacity is exhausted. It is important for businesses to verify the correct NDC when establishing communication infrastructure, as misdialing can lead to routing errors.

For VoIP and mobile users, the geographic nature of the code affects call routing and termination costs. Mobile numbers in Botswana are non-geographic and begin with '7' or '6', so 315 is strictly associated with fixed lines.
