What Is a NIN?

A National Identification Number (NIN) is a unique 11-digit number issued by the National Identity Management Commission (NIMC) to every Nigerian citizen and legal resident.

It serves as your centralized identity record tied to your biometrics and is now required for everything from SIM registration to banking and government services.

If you don’t have a NIN yet, you’ll need to visit a NIMC enrollment center to get one before you can complete the linking process.

Why You Need to Link Your NIN to Your MTN Line

This isn’t optional. The Nigerian government and Nigerian Communications Commission (NCC) require every subscriber to link their NIN to their registered SIM cards.

Here’s what’s at stake if you don’t:

Prevent your MTN line from being blocked or disconnected
Meet NCC and government SIM registration requirements
Protect your SIM from fraud, identity theft, and illegal usage
Keep uninterrupted access to calls, text messages, and internet services
Continue using services connected to your phone number, including mobile banking, BVN verification, and online account authentication.

Who Needs to Link NIN to an MTN Line?

Every MTN subscriber in Nigeria, prepaid or postpaid, individual or corporate. That includes:

New subscribers registering a SIM
Existing subscribers who haven’t linked yet
Anyone managing multiple lines, including corporate SIMs.

Bottom line: if it’s an active MTN line in Nigeria, it needs a linked NIN.

1. Link NIN to MTN via USSD Code

This is the quickest way: no internet, no app, and it works on any phone.

Direct Code: Dial *996*YourNIN# directly from your MTN line.

Menu-Based USSD (*785#):
