  • Complete the process by entering the two-digit numbers shown, then click on submit.

Method 3: Link via SMS

  • Subscribers who have secured their NIN but have not linked them with their mobile numbers can do so by simply texting their “NIN to 109” or “UPDATENIN NIN FirstName and LastName” to 109  e.g “UPDATENIN 12345678903 Firstname Lastname’ to 109.”

Alternatively, Glo customers can also call 109 to update their NIN via voice call.

Method 4: Link via NIMC App


One last method if none of the methods above worked is to try the NIMC Mobile ID App. But before you get started, it’s important to know that you’re required to have your National Identification Number (NIN) issued by the National Identity Management Commission or one of its accredited agents and a Mobile Number (which you used during enrolment for the NIN) – to receive an OTP for installing the Mobile ID app.
