Method 2: MTN NIN Online Portal (Best for Barred Lines)

If your line is already restricted and you can’t receive OTPs, this is your best option.

Visit https://nin.mtn.ng on your mobile phone and follow the steps below:

1. Enter your MTN phone number
2. Input your NIN
3. Complete verification
4. Submit

Why this works better for barred lines:

Method 3: Using the MyMTN App (Modern Option)

If you prefer to get things done through your apps, then the steps below are best for you:

1. Download and open the MyMTN NG App
2. Log in with your MTN number
3. Go to Profile or security section to select ‘link NIN’
4. Enter your NIN
5. Submit

This option is best for smartphone users and people who manage multiple MTN services.

Method 4: Virtual NIN (VNIN) — The 2026 Standard

The Virtual National Identification Number (VNIN) is a tokenized, 16-character alphanumeric, and temporary version of a citizen’s actual 11-digit National Identification Number (NIN), designed by the National Identity Management Commission (NIMC) to enhance data privacy during verification. 

The NIMC Mobile App (MWS Mobile ID) allows users to generate this token for specific and secure transactions such as SIM registration, banking, etc. This ensures that the verifying entity (e.g., MTN) cannot retain or misuse the original NIN. For MTN subscribers linking their NIN to a SIM card, the Enterprise Short-ID “109071” is the mandatory and specific ID used to generate a valid VNIN for MTN verification system.

How to Generate VNIN:

1. Use the NIMC Mobile App or portal
2. Select “Generate VNIN”
3. Enter MTN Enterprise ID: 109071
4. Generate your VNIN
5. Use that VNIN instead of your NIN when linking

Alternatively, you can dial *346*3*YourNIN*109071#.

You might be wondering what the advantage of the VNIN is, here is why the VNIN matters:

• Protects your real NIN from exposure
• Reduces fraud risk
• Now preferred by telecom providers

Lost Your NIN? Retrieve It Instantly

If you have lost your National Identification Number (NIN) slip or forgotten the number, you can retrieve it instantly using your mobile phone. The NIMC provides a quick, self-service method using the USSD. 

To do this, Dial *346# on the number you used for your NIN and then:

1. Select “Retrieve NIN”
2. You get charged ₦20 on your balance as service fee
3. Your NIN appears instantly

This works across all major networks, including MTN Nigeria.
