Area Code 442 – Bamako

Overview of Mali's +223 442 Geographic Prefix

The +223 442 prefix is a geographic National Destination Code (NDC) assigned to the Bamako capital district within Mali's national numbering plan, as administered by the Autorité Malienne de Régulation des Télécommunications (AMRT) in accordance with ITU-T E.164 recommendations. This prefix routes calls to fixed-line PSTN subscribers within the Commune IV and surrounding administrative zones of Bamako, Mali's political and economic capital. As a geographic code, +223 442 is tied to a physical location, and its usage is primarily associated with landline services provided by the incumbent operator SOTELMA (now part of Orange Mali) and other licensed fixed-line operators.

Geographic Coverage and Administrative Jurisdiction

The 442 prefix covers the central and northern districts of Bamako, including areas such as Lafiabougou, Djicoroni Para, and parts of the ACI 2000 business district. These zones host a mix of government institutions, commercial enterprises, and residential neighborhoods. The code is allocated exclusively to the Bamako capital district, which is a separate administrative entity from the surrounding Koulikoro Region, and it does not extend to other Malian cities or rural areas.

Dialing Formats and Caller Instructions

For international callers, the complete number format is +223 442 XX XX (or +223442XXXXX when dialed without spaces). For example, a landline number in Bamako might be dialed as +223 442 12 34. Local callers within Mali must dial the full national number including the NDC: 442 XX XX (omitting the +223 country code). For instance, a local call to the same number would be placed as 442 12 34. It is important to note that Mali uses a closed numbering plan, meaning the trunk prefix '0' is not used; callers must always dial the NDC and subscriber number without any leading zero.

Overlay and Numbering Considerations

As of the latest AMRT updates, no overlay code has been introduced for the Bamako area; the 442 prefix remains the primary geographic code for fixed-line services in the capital. However, due to the growing demand for telecommunication services, the regulator has been expanding the numbering capacity by introducing additional NDCs for fixed and mobile services. Subscribers under the 442 prefix are not subject to number portability between geographic and mobile networks, as mobile numbers in Mali use distinct non-geographic prefixes (e.g., 65, 66, 70, 71, etc.).

Practical Usage and Reliability

Fixed-line penetration in Mali is relatively low compared to mobile, but the 442 prefix remains essential for government offices, banks, and businesses that require reliable, secure communications. VoIP and IP-based services are increasingly used, but the 442 prefix is reserved for traditional PSTN connections. For callers from abroad, it is crucial to check with their service provider for international calling rates to Mali, as costs can vary. When dialing from a mobile phone, the plus sign (+) is typically used, followed by the country code and the full national number.
