How to Link Your NIN with Your 9Mobile SIM


In this post, we’ll discuss how to link your NIN with your 9Mobile SIM so that you’ll not be blocked from using your mobile line in the next two weeks.

What is NIN?

The National Identification Number (NIN) is the unique number that identifies you as a Nigerian and is issued to you at the completion of enrolment into the National Identity Database (NIDB) by NIMC. Once a NIN is assigned to an individual, it can never be reassigned, given, or used by another person – that makes it unique in nature. All citizens and legal residents in Nigeria, from age zero (birth) and above are eligible to enroll for their NINs.

Yes, it’s very important. The NCC issued out a circular warning that whoever doesn’t link their National Identification Number with their SIM will be blocked from using their mobile lines.
