USSD codes, the NIMC app, and the self-service portal — all methods in one place
Your NIN is 11 digits. You enrolled with NIMC at some point — maybe years ago — but the number isn't somewhere easy to find. Sound familiar? This is one of the most common problems Nigerians face before completing identity verification.
This guide covers every method to retrieve your NIN, whether you're on MTN, Airtel, Glo, or T2 Mobile, with or without internet access.
The Fastest Method: NIN USSD Code
The quickest way to check your NIN is to dial *346# on the phone number registered to your NIMC account. Your NIN will be displayed on screen within seconds — no internet required, works on all networks, and is completely free.
*346# works on MTN, Airtel, Glo, and T2 Mobile. It is the official NIMC NIN retrieval code — no third-party app or portal needed.
How to Check NIN on MTN
Dial *346# on your MTN line. If *346# doesn't work, you can also try MTN's NIN-specific menu by dialling *785# and selecting the option to view your NIN.
You can also text NIN to 785 to receive your NIN information via SMS.
How to Check NIN on Airtel
Dial *346# on your Airtel line. Alternatively, visit airtel.com.ng/nin and log in with your Airtel number to view your NIN linkage status and associated NIN.
How to Check NIN on Glo
Dial *346# on your Glo line. If this doesn't return your NIN, text NIN to 109 and Glo will respond with your NIN details.
How to Check NIN on T2 Mobile (formerly 9mobile)
Dial *346# on your T2 Mobile line. You can also text NIN to 200 to receive your NIN via SMS.
How to Check NIN Without a Phone Call — NIMC App and Portal
NIMC Mobile ID App
Download the official NIMC Mobile ID app from the Google Play Store or Apple App Store. Log in using your date of birth and the phone number used during NIMC enrolment. Your NIN will be displayed in your profile.
NIMC Self-Service Portal
Visit selfservicemodification.nimc.gov.ng and log in with your enrolment details. The portal lets you view your NIN, check linked phone numbers, and initiate modification requests.
How to Check Which Phone Numbers Are Linked to Your NIN
To see all SIM cards registered against your NIN, dial *346*3#. NIMC will return a list of all phone numbers currently linked to your identity. If you see numbers you don't recognise, contact NIMC immediately.
What to Do if Your NIN Doesn't Appear
If *346# returns no result, one of the following is likely:
- You enrolled on a different number: Your NIMC registration may be on a phone number you no longer use. Try *346# on other numbers you've had.
- You haven't enrolled yet: If you've never visited a NIMC centre, you won't have a NIN. Enrolment is free — visit any NIMC centre with a valid ID.
- Your number isn't linked to NIMC: Your phone number may not be the one registered during NIMC enrolment. Use the NIMC Self-Service Portal to check which number your NIN is tied to.
