When Ifeoma’s Airtel line stopped making calls out of nowhere, she thought it was a network glitch. But after restarting her phone five times and switching locations, she got a message: “Your line has been restricted due to unlinked NIN.” Turns out, she linked her NIN… but it didn’t go through.

In 2025, linking your NIN to your Airtel number isn’t something you do once and forget. It’s a critical part of keeping your SIM active and connected. Whether you’re registering a new Airtel SIM, trying to restore an old line, or simply avoiding disconnection, this guide walks you through how to link your NIN to Airtel the right way — step-by-step.

What is NIN and Its Importance

The National Identification Number (NIN) is a unique 11-digit number issued by the National Identity Management Commission (NIMC). It acts as your digital identity and is tied to important services like your SIM card, bank account, driver’s license, and more.

The Nigerian Communications Commission (NCC) has made it mandatory for all phone numbers to be linked to their owner’s NIN. Without it, Airtel and other providers are required to block or restrict your line.

How To Register For NIN In Nigeria

Don’t have a NIN yet? Here’s how to get one in Nigeria:

1. Visit an official NIMC Enrollment Center, such as NIMC branches, select banks, or even Airtel walk-in centers.
2. Pre-enroll online at nimc.gov.ng and print your registration slip.
3. Provide valid ID such as a BVN slip, voter’s card, or birth certificate.
4. Your photo and fingerprints will be captured.
5. Once processed, you’ll be issued a NIN slip containing your 11-digit number.

To retrieve a lost NIN, dial *346# from the phone number used to register.

How To Link NIN To An Airtel Line

Now that you’ve got your NIN, it’s time to link it to your Airtel SIM. Here are four easy methods:
