Geographic Scope and Assignment
The prefix +221 3397 is a geographic National Destination Code (NDC) assigned to the Dakar region of Senegal, specifically for numbers located outside the central Dakar zone. While the +221 country code covers all of Senegal, the 33 prefix historically denotes fixed-line services in the Dakar area, and the subsequent digits (in this case, 97) further refine the routing to a specific exchange or sub-region within the greater Dakar administrative area. This code is used for traditional PSTN (Public Switched Telephone Network) lines, as well as for fixed wireless and VoIP services that are allocated geographic numbers.
Dialing Formats and Usage
When calling a number with the prefix +221 3397, the full international format is +221 3397 XX XX, where the last four digits are the subscriber's line number. This results in a total of 9 digits after the country code (including the leading 33). For example, a complete number might appear as +221 3397 12 34.
- International callers must dial their international access code (e.g., 00 or +), followed by 221 (Senegal's country code), then the full NDC and subscriber number without any leading zero. For instance, from the US or UK, you would dial 011 221 3397 12 34 or 00 221 3397 12 34, respectively.
- Local callers within Senegal should dial the number in national format, which includes the trunk prefix '0' before the NDC. Thus, from a Senegalese landline or mobile, you would dial 0 3397 12 34.
- If you are calling from a mobile phone, it is often recommended to use the international format (+221 3397 12 34) to ensure proper routing, especially if the caller is roaming or the network requires it.
Overlay and Numbering Considerations
Senegal's fixed-line network has not implemented overlay codes in the traditional sense; instead, the 33 prefix is used for the Dakar region, and other prefixes (such as 34, 35, etc.) are used for other regions. The '97' sub-prefix is part of the NDC and is not separately assigned to a specific operator; rather, it is used by the incumbent operator Sonatel (Orange Senegal) for its fixed-line services. However, due to number portability, a number with this prefix may be routed to a different operator, but the geographic significance remains for billing and emergency services.
For callers, it is important to note that numbers beginning with +221 3397 are charged as fixed-line calls, which are typically less expensive than calls to mobile numbers. If you are unsure about the exact location, you can assume it is in the greater Dakar area, but the '97' block may serve specific neighborhoods or satellite towns such as Rufisque, Keur Massar, or other peri-urban zones. Always verify the number with the recipient if you need to know the exact physical address.
