About two weeks ago, Chinedu was out playing draft with his friends when he got a SMS from MTN: “Dear Customer, your line will be barred soon if you do not link your NIN.” He ignored it, thinking it was one of those regulatory empty threats. A week later, his line went dead right when he was expecting a critical business call. That was the moment reality hit. In 2025, linking your National Identification Number (NIN) to your MTN line isn’t optional, it’s essential.

Chinedu story isn’t unique. Many Nigerians who still haven’t linked their National Identification Number (NIN) to their mobile lines, have had their sims blocked. If you’re reading this, chances are you’re trying to avoid Chinedu’s experience or are already knee-deep in it. Either way, this guide will help you link your NIN to your MTN number in 2025, quickly and correctly.

What is NIN and Its Importance

The National Identification Number (NIN) is an 11-digit unique number assigned to every Nigerian by the National Identity Management Commission (NIMC). It’s more than just a number, it’s your digital identity. With rising concerns around security, fraud, and identity theft, the Nigerian government has made it mandatory to link your NIN with services like SIM cards, bank accounts, and even voter registration.

For MTN users, linking your NIN to your MTN line ensures your line won’t be deactivated and keeps your access to mobile banking, social media verification, and communication intact.

How To Register For NIN In Nigeria

If you don’t already have a NIN, here’s how to register for one:

1. Visit any NIMC Enrollment Center – These include official NIMC offices, banks like Zenith, UBA, and MTN service centers.
2. Fill out the pre-enrollment form online at nimc.gov.ng.
3. Bring valid means of identification such as a birth certificate, BVN, voter’s card, or driver’s license.
4. Biometric data will be captured including fingerprints and photographs.
5. You’ll receive a NIN slip with your 11-digit number after processing.

Make sure to keep your NIN slip safe, as you’ll need it for several services.
