How to Check Your NIN on MTN, Glo, Airtel & 9mobile
Quick answer
Dial the official NIMC USSD: *346# from the SIM that was used during your NIN registration. Follow the on-screen menu to view your 11-digit NIN.
Step-by-step: Check NIN on MTN, Glo, Airtel & 9mobile
- Open the phone app on the line you registered with NIMC.
- Dial *346# and press Call.
- From the menu that appears, choose the option to retrieve or display your NIN (usually option 1).
- Wait a few seconds — your 11-digit NIN will be shown on-screen.
Note: Make sure you dial the code on the exact SIM that was linked to your NIN during registration. If your SIM is not linked, the USSD will not return the NIN.
What to expect per network
The NIMC USSD *346# works on all major Nigerian mobile networks, including:
- MTN
- Glo
- Airtel
- 9mobile
Typical flow: Dial *346# → select the retrieve NIN option → view NIN on screen. A small service fee (commonly around ₦20) may be charged by your network or the service operator — fees can change, so expect slight variation.
Important tips & warnings
- Only use the SIM that was linked to your NIN when you registered with NIMC.
- Keep your NIN private — only share it with trusted institutions (banks, government services, official portals).
- If the code returns no result, visit an NIMC enrolment center or your network's customer care to confirm the SIM-to-NIN link.
- Scammers may ask for your NIN and other personal details — verify the request before sharing.
Why your NIN matters
Your NIN is a single, unique national identifier used for:
- SIM registration and linking
- Bank account verification and BVN processes
- Applying for government services (passport, driver’s licence, etc.)
- Identity verification for many online services
