Area Code 2077 – Bamako

Overview of Mali's Geographic Numbering Plan

Mali's national numbering plan adheres to ITU-T E.164, with country calling code +223. Geographic numbers are allocated by the Autorité Malienne de Régulation des Télécommunications (AMRT) and are structured as a fixed 8-digit national significant number (NSN). The first two digits represent the National Destination Code (NDC), which identifies a specific geographic area. The prefix 2077 is part of the NDC 207, designated for the Bamako capital district. Numbers under this prefix are used for fixed-line PSTN services within Bamako.

Geographic Coverage and Administrative Jurisdiction

The 2077 prefix is assigned to the Bamako District, the capital and largest city of Mali. This district is an administrative entity with its own governorate, distinct from the surrounding Koulikoro Region. The prefix covers all six urban communes of Bamako (Commune I through VI), including key neighborhoods such as ACI 2000, Badalabougou, Bamako Coura, Djicoroni, Hamdallaye, Hippodrome, Korofina, Lafiabougou, Magnambougou, Missira, N'Tomikorobougou, Ouolofobougou, Sogoniko, and Torokorobougou. As the political, economic, and cultural hub, Bamako hosts all national government institutions, foreign embassies, and major corporate headquarters.

Dialing Formats and Caller Instructions

For local callers within Mali, dial the full 8-digit subscriber number directly, including the NDC. For example, to reach a fixed line in Bamako with the number 2077-1234, dial 20 77 12 34. International callers must replace the leading '0' (if present) with Mali's country code +223. Thus, the same number is dialed as +223 20 77 12 34 from any foreign country. When calling from a mobile phone in Mali, the same 8-digit format applies. It is important to note that Mali does not use trunk prefix '0' in international format; the NDC is always included.

Overlay and Numbering Considerations

Currently, there is no overlay code for Bamako; the 207 NDC remains the sole geographic code for the district. However, due to increasing demand, the AMRT has implemented number pooling and reallocation measures. Subscribers may encounter numbers beginning with 2077 that are used for fixed wireless or VoIP services, but these are still considered geographic and tied to the Bamako area. For international callers, it is essential to verify the correct number, as misdialing may route to a different region or service.

Practical Usage and Examples

Businesses and government offices in Bamako commonly use 2077 numbers. For instance, a company's main line might be +223 20 77 45 67. When dialing from a landline in another Malian city like Sikasso, you would dial 20 77 45 67. From abroad, you would dial +223 20 77 45 67. Always ensure you have the correct number of digits; Mali's geographic numbers are exactly 8 digits long.
