Geographic Allocation and Coverage
The prefix 3398 is a geographic National Destination Code (NDC) assigned to the Thiès region of Senegal, located outside the capital, Dakar. This area code is part of the national numbering plan administered by the Agence de Régulation des Télécommunications et des Postes (ARTP) under the ITU-T E.164 standard. The 3398 code serves the city of Thiès and its surrounding administrative departments, including Tivaouane and Mbour, which are key economic and industrial hubs west of Dakar.
Thiès is the second-largest city in Senegal and a major railway junction, connecting Dakar to the interior of the country. The region is known for its tapestry industry, phosphate mining, and growing commercial activities. Subscribers with numbers beginning with 3398 are typically fixed-line PSTN connections, though some may be migrated to VoIP infrastructure while retaining the geographic identifier.
Dialing Formats and Instructions
When calling a fixed line in Thiès from within Senegal, you must dial the trunk prefix 0 followed by the NDC and the subscriber number. The national format is:
- 0 33 98 XX XX XX (e.g., 0 33 98 12 34 56)
From abroad, you need to replace the leading zero with Senegal's country code +221, resulting in:
- +221 33 98 XX XX XX (e.g., +221 33 98 12 34 56)
Note that the total number length after the country code is 9 digits, including the NDC. The NDC '33' indicates a fixed-line service in Senegal, and '98' further identifies the Thiès region. There are no overlay codes in this area; the 3398 prefix is unique to Thiès.
Caller Guidance
Local callers within Senegal should always include the '0' before the area code when dialing from a mobile or another fixed line. International callers must use the '+' notation or the international access code of their country (e.g., 00 from many European countries) followed by 221 and the 9-digit number. Calls to 3398 numbers are billed as standard fixed-line tariffs, which are typically lower than mobile rates. If you are unsure whether a number is fixed or mobile, remember that Senegalese mobile numbers start with 70, 75, 76, 77, 78, or 79.
