Area Code 215 – Kayes

Geographic Overview

The +223 215 prefix is a geographic National Destination Code (NDC) assigned to the Kayes Region in western Mali. Kayes is the administrative capital of the region and serves as a major transport hub near the Senegalese border. The code covers the city of Kayes itself and surrounding localities, including Kayes Ndi and adjacent communes. As a geographic allocation, the prefix is tied to the PSTN infrastructure of the region, although in modern deployments calls may be routed over IP backbones.

Dialing Formats

For international callers, the full number is dialed as +223 215 XX XX (or +223215XXXXX), where the subscriber number typically consists of five digits following the NDC. The complete international number is 12 digits long, including the country code. Local callers within Mali must dial 215 XX XX (without the +223) when calling from another fixed line or mobile network. When dialing from abroad, the leading '0' (if any) is omitted; Mali uses no trunk prefix, so the number format remains consistent.

Caller Instructions

• From outside Mali: Dial the international access prefix (e.g., 00 or +), then 223 (country code), then 215 (area code), followed by the five-digit subscriber number. Example: +223 215 12345.
• From within Mali: Dial 215 12345 directly from any fixed or mobile line. No trunk prefix is required.
• For local calls within Kayes: The same format applies; the area code is always required, as Mali does not use local number portability or overlay codes in this region.

Technical Considerations

The Kayes region operates under the Malian national numbering plan, which follows ITU-T E.164 recommendations. The country code +223 is assigned to Mali, and the NDC 215 is part of the geographic routing structure. The subscriber number length may vary slightly depending on the operator, but the total length of the international number (country code + NDC + subscriber number) is fixed at 12 digits. Calls to this prefix are typically routed over the public switched telephone network (PSTN) or via VoIP gateways that interconnect with the Malian national network.

For businesses or individuals requiring reliable connectivity in Kayes, it is advisable to confirm the exact subscriber number length with the local service provider, as some numbers may have been migrated to VoIP without changing the prefix. However, the geographic significance of +223 215 remains unchanged for routing and billing purposes.
