| How to Know Your MTN SIM Registration Status (NIN Linked or Not) in 2025 |
Want to check if your MTN SIM is linked to your NIN? This 2025 guide shows simple USSD codes and online methods to verify your MTN registration status in Nigeria.
Why You Should Check Your MTN SIM Registration Status
With Nigeria’s telecom regulations requiring all SIM cards to be linked with a valid National Identification Number (NIN), it's important to confirm whether your MTN line is properly registered. Failure to link your NIN could lead to disconnection or restricted service.
How to Check If Your NIN is Linked to Your MTN SIM
There are three simple ways to confirm your SIM registration status on MTN:
1. Using USSD Code
- Dial
*996#on your MTN line - Select option for “NIN Status”
- You’ll receive a message telling you whether your NIN is successfully linked or not
Note: This code works even without internet access.
2. Through MTN Website or NIN Portal
- Visit the MTN NIN update portal:
👉 https://nin.mtn.ng - Input your MTN number and follow the instructions to check your status
3. MTN App (MyMTN App)
If you already use the MyMTN App, you can check your NIN status by:
- Opening the app
- Logging in with your number
- Navigating to the “NIN Status” section
- Your linked status will be displayed
If you don’t have the app yet, download from the links below:
What to Do If Your NIN Is Not Linked
If the result says your NIN is not yet linked, quickly link it using any of the following:
Option 1: USSD
- Dial
*785*NIN#
(e.g., 78512345678901#)
Option 2: MTN NIN Portal
- Visit https://nin.mtn.ng and fill your details
Important Notes
- If your SIM isn’t linked, you may lose call, text, or data access
- Only use your own NIN—linking with another person’s may result in SIM deactivation
- You can retrieve your NIN by dialing
*346#if it was previously registered
Checking your MTN SIM registration status is quick and easy. By using the USSD code, the MTN website, or the MyMTN app, you can confirm your NIN status and avoid unexpected service disruption.
