How to Get Your NIN Number on MTN |
Wondering how to get your NIN number on MTN in 2026? Whether you've forgotten your National Identification Number (NIN), want to retrieve it, or need to link it to your MTN SIM, this updated guide explains the easiest and latest methods available in Nigeria.
The Nigerian government, through the National Identity Management Commission (NIMC) and the Nigerian Communications Commission (NCC), continues to require every SIM card to be linked with a valid National Identification Number (NIN). If your MTN line is not linked, you may experience restrictions such as blocked outgoing calls or complete SIM deactivation.
Fortunately, retrieving your NIN or linking it to your MTN line is simple and can be completed within minutes.
What Is a National Identification Number (NIN)?
The National Identification Number (NIN) is a unique 11-digit number issued by the National Identity Management Commission (NIMC) after successful enrollment. It serves as your permanent identity number and is used across many government and financial services in Nigeria.
Today, your NIN is required for:
- Registering and reactivating SIM cards
- Opening bank accounts
- Obtaining or updating your Bank Verification Number (BVN)
- Applying for an international passport
- Driver's licence applications
- Government intervention programmes
- Accessing various public and private sector services
How to Retrieve Your NIN Number on MTN
If you have already enrolled with NIMC but cannot remember your NIN, you can retrieve it using any of the methods below.
Method 1: Dial the Official NIN USSD Code
This remains the quickest method.
Follow these steps:
- Insert the SIM card linked to your NIN.
- Dial *346#.
- Select NIN Retrieval.
- Follow the on-screen instructions.
- Your 11-digit NIN will appear on your screen.
Important: A small service charge may apply, depending on current NIMC pricing.

If you have internet access, you can retrieve or manage your NIN information online through the official NIMC self-service platform.
This option is useful if you also want to update or verify your personal details.

The officials can help you retrieve your NIN or reprint your NIN slip if necessary.
