Following directives from the Nigerian Communications Commission (NCC), all SIM cards in Nigeria must be linked with the National Identification Number (NIN) issued by the National Identity Management Commission (NIMC). This policy, enforced since December 2020, aims to curb security challenges, improve national identity management, and control the use of mobile lines for fraudulent activities.
Failure to link your NIN to your SIM card could lead to restricted or blocked lines by network providers like MTN, Airtel, Glo, and 9mobile. Thankfully, the process is straightforward and can be done via USSD codes, online portals, or through your telecom provider’s customer care center.
This guide walks you through the different methods you can use to link your NIN to your SIM card — whether you’re using MTN, Airtel, Glo, or 9mobile.
