Area Code 212 – Koulikoro

Geographic Overview

The +223 212 numbering block is a geographic area code assigned to the Koulikoro Region of the Republic of Mali. Koulikoro is the second-largest administrative region in Mali, serving as a vital economic and logistical corridor between the capital, Bamako, and the interior of the country. The region shares its name with its principal city, Koulikoro, which lies approximately 60 kilometers northeast of Bamako along the Niger River. The area code covers the urban center of Koulikoro and its surrounding communes, including the towns of Kati, Kangaba, and Dioïla, which are integral to the region's administrative and commercial activities.

Dialing Formats and Usage

When dialing a landline number within the Koulikoro region from another fixed line in Mali, subscribers must use the national trunk prefix 0 followed by the area code and the subscriber's seven-digit number. For example, a local call to a Koulikoro landline would be dialed as 0 212 XX XX XX. However, from a mobile phone within Mali, the same number can be dialed in the international format without the leading zero, as +223 212 XX XX XX, because mobile networks in Mali typically require the full international format for all calls.

For international callers, the correct dialing sequence is the Mali country code +223, followed by the area code 212 and the seven-digit local number. For instance, a caller from abroad would dial +223 212 XX XX XX to reach a fixed line in Koulikoro. It is important to note that the area code is an integral part of the national numbering plan and must always be included when dialing from outside the country.

Regulatory and Technical Considerations

The Malian telecommunications regulator, the Autorité Malienne de Régulation des Télécommunications (AMRT), administers the national numbering plan in accordance with ITU-T E.164 recommendations. Geographic area codes like 212 are allocated exclusively for fixed-line services, and their use is tied to the physical location of the subscriber's line. This means that the prefix does not support nomadic or mobile use; it is strictly associated with the PSTN infrastructure in the Koulikoro region.

As Mali continues to modernize its telecommunications infrastructure, there have been discussions about number portability and the potential introduction of overlay codes to address the growing demand for fixed-line services. However, as of the latest updates, the 212 area code remains the sole geographic code for Koulikoro, and no overlay has been implemented. Subscribers and callers should always verify the correct dialing format with their service provider, especially when making international calls, to ensure accurate routing and avoid call failures.
