If you use MTN in Nigeria, one of the most important things you must do is link your MTN number to your NIN (National Identification Number). This is a compulsory requirement from the Nigerian government through NIMC for all mobile networks.

The challenge is that many MTN users do not know whether their line is linked or not. Some linked it years ago but are not sure if it was successful. Others tried linking but did not receive confirmation. And some are afraid their lines may soon be blocked.

The good news is that MTN has provided simple and fast ways to check your NIN–SIM linkage status using USSD, SMS, MTN App, and the MTN website.

This article explains everything in a clear, easy-to-understand way, even if you are not tech-savvy.

This is the fastest and most reliable method.

*USSD Code: 996#

Steps:

1. Dial *996# on your MTN line.
2. Select “NIN-SIM Link Status” or “Check NIN Status” (menu options may vary).
3. MTN will show you if your line is already linked or not.
4. If it is linked, you will see a confirmation message.
5. If not linked, MTN will ask you to enter your NIN immediately.

This USSD code works without internet and on all phones, including small button phones.

How to Check Your MTN NIN Status Using the MTN NIN Portal

MTN has an online portal where users can confirm if their line is linked.

Steps:

2. Enter your MTN phone number.
3. You will receive an OTP (one-time password).
4. Enter the OTP to verify your identity.

MTN sends SMS alert messages when you successfully link your NIN.
You can check your old messages to confirm.

Search your SMS inbox for keywords like:

• NIN linked
• SIM registration successful
• Your MTN number is now linked
• NIMC verification successful

If you find the message, it means your number was linked earlier.

If you can’t find the message, use the USSD code to confirm.

Another simple way to check your NIN status is by contacting customer care.

MTN Customer Care Number: 300

   • Last recharge amount
   • Last 3 dialed numbers
5. They will then tell you if the number is linked or not.

This option is helpful if the USSD code is not working.
