Frequently Asked Questions

Senegalese phone numbers have a 9-digit structure, represented as NXX XXX XXX, where 'N' indicates the service type (3 for landlines, 7 for mobile) and 'X' is any digit from 0 to 9. Landlines follow the format 3XX XXX XXX, while mobile numbers are 7XX XXX XXX. For example, a Dakar landline might be 338 219 903, and a mobile number could be 778 688 219.
Use regular expressions (regex) to validate Senegalese phone numbers. For example, in JavaScript, the regex /^3[3-6]\d{7}$/ validates landlines, and /^7[0567-8]\d{7}$/ validates mobile numbers. Remember to clean the number by removing spaces and special characters before validating.
The country code for Senegal is +221. When calling Senegal from another country, you must dial +221 followed by the 9-digit phone number. For example, to call the number 778 688 219 from internationally, you would dial +221 778 688 219.
The E.164 format for Senegalese numbers is +221NXXXXXXXX, where N is the service category digit (3 or 7) and X represents the remaining 8 digits. This international standard ensures consistent formatting for global interoperability. For example, the number 778 688 219 becomes +221778688219 in E.164 format.
Senegal's mobile penetration rate exceeds 100% due to significant growth and modernization in the telecommunications sector, primarily driven by the mobile segment. Many individuals have multiple SIM cards or subscriptions. This vibrant mobile market is served by three main operators: Orange Senegal, Free Senegal, and Expresso Senegal.
Each mobile operator in Senegal has specific prefixes within the 7XX XXX XXX format. Orange Senegal uses 70X and 76X, Free Senegal uses 77X and 78X, and Expresso Senegal uses 75X. Knowing these prefixes can be crucial for routing calls and SMS messages correctly.
Number portability in Senegal allows users to switch operators while keeping their number. To handle this, integrate with a number portability database or lookup service to determine the current operator of a number. Implement robust error handling for cases where the lookup service is unavailable. Consider caching lookup results to reduce latency.
The first three digits of a landline number (3XX) represent the geographic zone. 33X corresponds to the Dakar Metropolitan Area, 34X to Northern Regions, 35X to Central Regions, and 36X to Southern Regions. This information can be useful for location-based services.
ARTP (Autorité de Régulation des Télécommunications et des Postes) is the regulatory authority for Senegal's telecommunications sector. They oversee regulations, technical specifications, and number allocation procedures. Staying updated on ARTP guidelines is essential for regulatory compliance.
Allocating premium numbers involves an application phase with technical and financial assessments, a technical evaluation phase for network compatibility, and an implementation phase for network configuration and activation. Contact ARTP for detailed procedures and pricing.
Consider integrating number portability functionality if your application involves routing calls or SMS messages, identifying the correct operator, or any operation where knowing the current operator of a number is essential. While it adds complexity, it ensures accurate routing and operator identification.
Golden numbers are ultra-premium, highly sought-after numbers in Senegal available through a competitive bidding process. They often command significantly higher prices than standard numbers due to their memorability and exclusivity. Contact ARTP for details about acquiring golden numbers.
