Area Code 2220 – Bujumbura

Geographic Coverage and Administrative Jurisdiction

The area code 2220 is a geographic National Destination Code (NDC) assigned to the city of Bujumbura, the economic capital and largest city of Burundi. Bujumbura serves as the administrative, commercial, and industrial hub of the country, hosting the central government institutions, foreign embassies, and major businesses. The code covers the urban and peri-urban zones of Bujumbura Mairie, including districts such as Mukaza, Ntahangwa, and Kinindo. As a geographic code, it is tied to the PSTN infrastructure of the city, and its use is independent of any particular operator.

Dialing Formats and Caller Instructions

For local callers within Burundi, the national significant number (NSN) for Bujumbura numbers is eight digits long, beginning with the trunk prefix 0 followed by the NDC 2220. Thus, a local call to a Bujumbura number would be dialed as 0 2220 XX XX (where X represents the subscriber's four-digit line number). For example, a local call to a subscriber line would be 0 2220 1234.

International callers must dial the Burundi country code +257, followed by the NDC 2220 and the subscriber number, omitting the leading trunk prefix. Hence, an international call from abroad would be dialed as +257 2220 1234. It is important to note that Burundi uses a closed numbering plan; therefore, the national significant number is always eight digits, and the trunk prefix 0 is only used for domestic calls.

Overlay Considerations and Numbering Plan Evolution

Currently, there is no overlay code for Bujumbura; the 2220 code remains the sole geographic code for the city. However, as Burundi's telecommunications sector evolves, the regulator (ARCT) may introduce additional NDCs or migrate to a unified numbering plan. Subscribers in Bujumbura may also have numbers from mobile operators, which use separate non-geographic prefixes (e.g., 79, 69, 61), but those are not part of the geographic code. For fixed-line services, the 2220 code is the primary identifier for Bujumbura's PSTN network.

Practical Guidance for Callers

• Local callers: Dial 0 2220 XXXX (using the trunk prefix).
• International callers: Dial +257 2220 XXXX (omit the trunk prefix).
• Callers from mobile phones within Burundi: May dial either format, but the trunk prefix is generally required.
• For directory assistance: Contact your service provider for local directory services.

Understanding the correct dialing format ensures seamless connectivity to businesses, government offices, and residents in Bujumbura. Always verify the subscriber number length (four digits after the NDC) to avoid misdialing.
