How to Check Your NIN on MTN, Glo, Airtel & 9mobile

Retrieve your National Identification Number (NIN) instantly using the official NIMC USSD — works across major networks.

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

1. Open the phone app on the line you registered with NIMC.
2. Dial *346# and press Call.
3. From the menu that appears, choose the option to retrieve or display your NIN (usually option 1).
4. 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

Frequently asked questions (FAQ)

Q: My USSD shows no NIN. What do I do?

A: Your SIM may not be linked to your NIN. Visit a NIMC enrollment center or contact your network provider (MTN, Glo, Airtel or 9mobile) for help linking the SIM to your NIN.

Q: Is there a charge to check my NIN with *346#?

A: A small fee (often around ₦20) is commonly applied, but this can vary. Treat the amount as indicative and expect slight differences.

Q: Can I use any phone to dial *346#?

A: Yes, but you must dial from the specific SIM that was linked to your NIN. Dialing from another SIM will not retrieve the correct result.
