In 2025, everything seems to need a digital stamp of approval — banking, passports, even SIM cards. So when Chuka tried to upgrade his Glo SIM to 5G and was told his line wasn’t NIN-linked, he was shocked. “But I did that two years ago!” he said. Turns out, the link had failed silently, and his line was one regulatory sweep away from being blocked.

Don’t be like Chuka.
If you’re using Glo in Nigeria, linking your NIN to your Glo number is no longer optional. It’s mandatory, and failing to do it right could mean losing access to mobile banking, calls, data, and more. The good news? Linking your NIN to your Glo line in 2025 is quick, free, and can be done in multiple ways.

What is NIN and Its Importance

Your National Identification Number (NIN) is a unique 11-digit number issued by the National Identity Management Commission (NIMC). It ties together all your official records — your SIM card, bank accounts, voter registration, and even immigration data.

In line with government directives, all Nigerians must link their NIN to their mobile numbers, including Glo, to enhance national security, prevent identity fraud, and streamline services.

Without linking your NIN to your Glo line, you risk having your SIM deactivated or limited, affecting your ability to make calls, receive OTPs, or use mobile data.

How To Register For NIN In Nigeria

Before linking your NIN to your Glo number, you need to have one. If you don’t, here’s how to register:

1. Visit a NIMC Enrollment Center – This includes NIMC offices, designated banks, or licensed telco centers like Glo service shops.
2. Pre-enroll online at nimc.gov.ng and print the slip.
3. Bring valid identification such as a voter’s card, BVN, birth certificate, or passport.
4. You’ll provide biometric data like fingerprints and a facial photo.
5. After processing, you’ll receive a NIN slip with your official 11-digit NIN.

Pro Tip: Dial *346# to retrieve your NIN from any number linked during enrollment.
