If you’ve already registered your SIM card but haven’t linked it with your NIN, it’s important to act immediately—failure to do so may result in your line being blocked.
The Nigerian Communications Commission (NCC) mandates that all mobile numbers be connected to a valid National Identification Number (NIN). In line with this directive, telecom operators have been instructed to deactivate unlinked lines after a given deadline.
Don’t worry if you haven’t completed the process yet. This guide outlines the fastest and easiest ways to connect your NIN to your line.
Before You Begin: What You’ll Need
Before you can link your NIN to your phone number, ensure the following:
1. Your SIM Card Must Be Registered
This is the foundational step. Your line must be properly registered with your telecom provider. If it’s not, visit the nearest MTN, Glo, Airtel, or 9Mobile outlet to register or re-register your SIM.
2. You Must Be Enrolled for NIN
Without a valid NIN, you cannot proceed. To register for one:
Go to the nearest NIMC office or an authorized enrollment center.
Take along valid documents such as a birth certificate, national ID card, driver’s license, or international passport.
Complete the NIN form and biometric registration process. After this, your unique NIN will be generated.
4 Ways To Link Your NIN To Your SIM In 2025
Once you have your NIN and an active, registered SIM, you can link them through one of the methods below:
1. Link Via USSD Code
The easiest method is by dialing the universal short code *996# from any line. Follow the on-screen instructions to submit and connect your NIN to your mobile number.
2. Link Through Network Provider’s Website
MTN Users
Visit the MTN NIN Linking Portal.
Enter your phone number and email to receive a one-time password (OTP).
Enter the OTP to proceed.
After verification, the portal will assess your NIN status and complete the linking if all is correct.
Airtel Users
Go to the Airtel NIN Portal.
Input your phone number and confirm with an OTP sent to your line.
Once verified, your NIN will be checked and linked accordingly.
> ⚠️ Note:
Glo and 9Mobile currently don’t offer a direct online NIN linking portal like MTN and Airtel. However, you can still visit their official websites or physical service centers to get the latest instructions on linking your NIN.
3. Link Using the NIMC Mobile ID App
The NIMC mobile app offers a secure way to manage and link your NIN to multiple mobile numbers. Here’s how:
1. Download and install the NIMC Mobile ID App.
2. Log in with your NIN and security PIN.
3. Select the “Link NIN” or “Add Mobile Number” option.
4. Enter the phone number and submit the OTP sent to that line.
> ✅ Tip: You can repeat the process to link more lines (up to 7 SIMs in total).
4. Visit the Nearest Network Provider’s Office
If you’re experiencing issues online or prefer face-to-face assistance, walk into any nearby customer care center (MTN, Airtel, Glo, or 9Mobile) to complete your NIN-SIM linking.
What is a Virtual NIN (VNIN)?
A Virtual NIN is a secure, temporary 16-digit version of your actual NIN used for verification during transactions. It is valid for one-time use and expires within 24 hours.
To generate a VNIN:
- Open the NIMC Mobile ID App.
- Choose the “Generate Virtual NIN” option.
Note: This service may incur a small charge, so make sure you have airtime.
Can I Link My NIN To More Than One SIM?
Yes, a single NIN can be linked to up to seven different phone numbers. To do this using the NIMC App:
- Open the app and tap “Add Mobile Number”
- Enter the number you wish to link and confirm with the OTP.
- Repeat this process for each additional line.
What Documents Are Required for NIN Registration?
To enroll for your NIN, visit an NIMC center with your BVN and at least one valid document, such as:
- International Passport
- Driver’s License
- Voter’s Card
- School ID or Government Staff ID
- Tax Clearance Certificate
- NHIS ID Card
- Declaration of Age
