Area Code 2230 – North zone

Geographic Overview

The +257 2230 prefix is a geographic National Destination Code (NDC) assigned to the North zone of Burundi, specifically serving the province of Ngozi and its surrounding communes. This area is part of the northern highlands, bordering Rwanda to the north, and includes localities such as Ngozi City, Kiremba, and Marangara. The prefix is administered under the national numbering plan of Burundi, which follows ITU-T E.164 recommendations.

Dialing Formats

When dialing a number in this region from within Burundi, subscribers must use the national significant number (NSN) in the format 22 30 XX XX. For example, a local number might be 22 30 45 67. To call this number from a fixed line or mobile phone within Burundi, simply dial the eight-digit number: 22304567.

For international callers, the full international format is required: +257 22 30 XX XX. Thus, the same example would be dialed as +257 22304567 from abroad. Note that Burundi uses a single country code, +257, and there is no trunk prefix (such as '0') used in the national dialing; the NDC is always included in the national number.

Caller Instructions

• Local callers (within Burundi): Dial the eight-digit number directly, e.g., 22304567. No area code is needed beyond the NDC.
• International callers: Dial the international access prefix (e.g., 00 from most countries, or + from mobile), then the country code 257, followed by the NDC and subscriber number: +257 22304567.

Network and Regulatory Notes

The 2230 prefix is part of the geographic numbering range allocated to fixed-line services. It is operated by the incumbent fixed-line operator, though in recent years, some VoIP and wireless local loop services have been assigned numbers from geographic ranges to support fixed-mobile convergence. The numbering plan is regulated by the Agence de Régulation et de Contrôle des Télécommunications (ARCT) of Burundi. As of the latest updates, there are no overlay codes for this area; the NDC remains unique for Ngozi province. However, with the growth of IP-based telephony, geographic numbers like these can be ported to VoIP providers, but the tariff structure may vary depending on the service provider.

For businesses or individuals in the North zone, having a geographic number like 2230 reinforces a local presence and can be more cost-effective for incoming calls from within the region. When dialing from mobile networks, standard rates apply, but many operators offer on-net or local call discounts.
