Area Code 3394 – Outside Dakar

Overview of Senegal's +221 3394 Geographic Prefix

The +221 3394 prefix is a geographic National Destination Code (NDC) assigned to the Thiès region, located outside the Dakar capital area. This code is part of Senegal's national numbering plan, which follows ITU-T E.164 recommendations. The full international dialing format is +221 33 94x xx xx, where '33' indicates the fixed-line service and '94' identifies the specific central office or exchange within the Thiès region. The prefix serves both residential and business subscribers connected to the PSTN (Public Switched Telephone Network) and is also used by VoIP providers offering fixed-line services.

Geographic Coverage and Administrative Jurisdiction

The 3394 prefix is allocated to exchanges in the Thiès Department, part of the Thiès Region, which is an important administrative and industrial hub approximately 70 kilometers east of Dakar. The coverage area includes the city of Thiès itself and surrounding communes such as Fandène, Khombole, and Pout. This region is known for its railway connections, phosphate mining, and growing manufacturing sector. The prefix is used for fixed-line services within this zone, and callers should note that the geographic allocation is independent of mobile networks.

Dialing Formats and Caller Instructions

For local callers within Senegal, the number is dialed in the national format: 33 94x xx xx (without the leading '0' that is common in some countries). For international callers, the format is +221 33 94x xx xx (or 00221 33 94x xx xx from countries using the international prefix '00'). When calling from a mobile phone in Senegal, the same national format applies. It is important to note that Senegal does not use trunk prefixes like '0' for domestic long-distance calls; the full NDC (including '33') is always dialed.

Overlay Considerations and Numbering Plan Stability

As of the latest updates, there is no overlay code for the Thiès region; the 3394 prefix is exclusive to this geographic area. However, Senegal's telecom regulator (ARTP) has implemented number portability for fixed lines, allowing subscribers to retain their numbers when changing operators within the same geographic area. This means that a number starting with 3394 may be serviced by a different operator than originally assigned, but the geographic association remains unchanged. The numbering plan is expected to remain stable, with no immediate plans for prefix changes or reallocations.

Practical Examples

• Local call (within Senegal): 33 941 23 45
• International call (from abroad): +221 33 941 23 45
• International call (using 00): 00221 33 941 23 45

When calling from a foreign country, ensure you replace the '+' with your country's international exit code (e.g., '011' from the US, '00' from most European countries). Always verify the complete number with the recipient, as the prefix is part of the national numbering plan and cannot be omitted.
