If you use MTN in Nigeria, linking your National Identification Number (NIN) to your line is not just a recommendation, it’s a requirement. The Nigerian Communications Commission (NCC) made this process mandatory to strengthen national security and improve digital identity verification.
Whether your SIM is active or blocked, this guide will show you how to link your NIN to your MTN number quickly and without stress.

Why You Need to Link Your NIN to Your MTN Line
Your NIN connects your phone number to your verified identity; a vital step in ensuring safety and trust in Nigeria’s telecom space. Without linking it, your line could be restricted from making or receiving calls.
So if you’ve been wondering “how do I link my NIN to MTN?” or “how to link my MTN SIM with NIN?”, you’re in the right place.
How to Link Your NIN to Your MTN Number via USSD Code
The fastest and easiest way to link your NIN to your MTN SIM is through a USSD code. No data or smartphone required.
- Open your phone’s dialer.
- Dial *996*your NIN#. For example, *996*12345678901#.
- Press “Send.”
- Wait for a confirmation message from MTN.
If your NIN is valid and correctly registered, MTN will verify it and send you a success message.
This method works perfectly for anyone searching “how to link NIN to MTN,” “how to link NIN on MTN,” or “how to link NIN to MTN number.”
How to Link Your NIN to Your MTN Number via SMS
Another quick way is to use SMS; simple and effective. Here’s how to link NIN to MTN via SMS:

- Send it to 996.
MTN will acknowledge your message and begin the verification process. Once successful, you’ll receive confirmation that your NIN has been linked to your MTN line.
