How to Check Your NIN Number: USSD Code and Online Methods

Your National Identification Number (NIN) is a unique 11-digit number assigned to you after registration with the National Identity Management Commission (NIMC). If you have forgotten your NIN, you can retrieve it using the phone number linked to your NIN registration.

How to Check Your NIN Number

The most common way to retrieve your NIN is through the NIMC USSD service. Dial *346# from the mobile number you used during NIN enrolment and select the option for NIN retrieval. Follow the instructions displayed on your phone to complete the request.

What You Need to Retrieve Your NIN

How to Retrieve NIN With USSD

1. Insert the SIM card linked to your NIN into your phone.
2. Dial *346#.
3. Select the NIN retrieval option from the menu.
4. Follow the instructions provided.
5. Confirm the request when prompted.

The service may attract a small network service charge. The exact amount can depend on the current charge applied by your mobile network.

Can I Check My NIN Online?

If you have previously received or saved your NIN, you can find it on documents such as your NIN slip. NIMC also provides digital identity services through its official platforms. For security reasons, avoid entering your personal information into unofficial websites claiming to retrieve NIN details.

What If *346# Does Not Work?

First check that you are using the phone number associated with your NIN registration. If the USSD service still fails, try again later because network interruptions can affect USSD services. You can also visit a NIMC enrolment or service centre for assistance.

Where Can I Find My NIN Without USSD?

Your NIN may already be printed on your NIN slip or other official NIMC documentation. If you previously saved a digital copy of your slip, search your phone, email or secure document storage for it.

Can I Retrieve Someone Else’s NIN?

NIN information is personal identification information. You should only retrieve and use your own NIN unless you are legally authorised to handle another person’s identity information.

Keep Your NIN Safe

Avoid posting your NIN publicly or sending a copy of your identity documents to unknown individuals. When a bank, telecommunications company or government service requests your NIN, use the organisation’s official channels and provide the information only when required.
