How to Link NIN to MTN, Airtel, 9Mobile or Glo and the Codes to Use

The National Identity Number (NIN) is an 11-digit number that the Nigerian Government uses to tie all citizens’ records in the National Identity Database and to phone numbers across MTN, Airtel, 9Mobile or Glo network. These data include fingerprints, facial pictures, digital signatures, and other demographic data.

When one successfully registers with the National Identity Management Commission (NIMC), a body responsible for enrolling people, the system generates special numbers that carry every detail about that citizen. This special number is the National Identity Number, and it is unique to the individual bearing it. In this piece, we will find out how to link NIN to our mobile numbers.

To make it easier for the Nigerian government to bring everyone out for the enrollment exercise, they mandated all citizens to link their NIN to their mobile numbers. Failure to do so, their phone numbers will be blocked. A deadline for linking the mobile numbers was set to December 2020, but it has continuously been moved from one month to another. This has brought many to the enrollment centers, and a good number have registered.

However, many more are yet to register due to one reason or the other. Some are not patient enough to wait for the queues they find at the centers, while others are in the rural areas and have not had the opportunity to do so. Many other Nigerians who are outside the country have also not enrolled.
