2. Checking via NIMC Mobile App
The NIMC Mobile App provides an easy way to access your number without using USSD codes.

- Download and install the NIMC Mobile App from the Google Play Store or Apple App Store.
- Open the app and log in using your registered phone number and details.
- Once logged in, your number will be displayed on the app’s dashboard.
This method is safe and ensures that your details remain secure.
3. Visiting an NIMC Enrollment Center
If you no longer have access to your registered phone number or need official verification, you can visit an NIMC office. This method is best for those who need an official printout of their number.
- Locate the nearest NIMC enrollment center.
- Provide your personal details (Full Name, Date of Birth, and Registered Phone Number).
- An officer will help retrieve your number after verifying your identity.
Ensure you carry a valid means of identification, such as a voter’s card, driver’s license, or passport, for faster processing.
4. Checking Your NIN Slip
When you first registered, you were given a NIN slip that contains your unique 11-digit number. If you still have your slip, you can check your number easily.
- Find your slip and check the top-left corner.
- The number is printed on the slip and can be used for any necessary identification.
If your NIN slip is lost, you can request a reprint at an NIMC office.
Other Ways to Retrieve Your NIN
If none of the above methods work, you can visit your bank if you have linked your NIN to your bank account. Some banks allow customers to check their NIN at their branches.
You may also check with your telecom provider if you linked your NIN to your mobile number. Some service centers can retrieve it upon request.
