Identity (NIMC)
How to check your NIN status online.
How to check your NIN status online: by USSD, in NIMC's NINAuth app, and what to do if your NIN is not found, not linked or shows the wrong details.
Your National Identification Number (NIN) is the spine of every government identity check in Nigeria — banking, SIM registration, passport, driver's licence, your Tax ID. Before you rely on it for any of those, it helps to confirm it is active, correctly linked, and shows the right details. This guide covers how to check your NIN status, and what each outcome means.
The quickest check: USSD
The fastest way to confirm a NIN exists against your phone number is the NIMC USSD code. Dial *346# from the phone number registered to your NIN and follow the prompts. It returns your NIN (or confirms the number linked to that line). It costs about ₦50 in airtime.
USSD is the right tool when you just need to retrieve or confirm your NIN quickly and you have your registered SIM to hand.
The NINAuth app
NINAuth (ninauth.nimc.gov.ng) is NIMC's identity app and website, with the app on Google Play and the Apple App Store. NIMC's older mobile ID app has gone from the app stores.
You can download your NIN slip in NINAuth free. Use it to confirm not just that the NIN exists, but that the name, date of birth, and photo on the record are correct.
Checking your NIN is linked where it matters
"Active" is not the same as "linked." A NIN can be valid but not yet linked to the service that needs it. The common ones to check:
- SIM–NIN link — confirm with your telco; an unlinked line risks being barred.
- BVN–NIN consistency — banks increasingly require the name and date of birth on your NIN and BVN to match.
- Passport and driver's licence — both read the NIN as the source of truth, so a mismatch blocks those applications.
What "NIN not found" usually means
If a check returns "not found" or no record, the usual causes are:
- The phone number you are checking from is not the one registered to the NIN.
- Enrolment was never completed — a pre-enrolment slip is not the same as an issued NIN.
- A data entry error at enrolment left the record inconsistent.
- The slip is lost and you have forgotten the number — retrieve it via *346# from your registered line.
If the details are wrong
If your NIN is active but the name, date of birth, or other detail is wrong, the fix is a NIN modification, not a re-check. A wrong detail will block your passport, licence, or bank application downstream, so correct it before you need it. See what NIN modification is, and the NIMC hub.
If the slip is lost
If your NIN itself is fine but you have lost the physical slip, you do not need a new NIN — you need a reissue of the slip. The number stays the same; you just get a fresh copy of the slip. NIMC charges ₦600 to reissue a slip, and the NINAuth app lets you download it free.
On Docufy a slip reissue needs no office visit: you upload a government ID, plus a police report if the slip was lost (or the damaged slip, if it was damaged). The price and target time are on the NIN slip reissue page. For more on NIN fees and records, see our NIN and NIMC guides.
Questions
Frequently asked.
How do I check my NIN status?
The quickest way is to dial *346# from the phone number registered to your NIN, which returns or confirms the number. For full details — name, date of birth, photo — sign in to NIMC’s NINAuth app and download your NIN slip.
What does it mean if my NIN is "not found"?
Usually one of: you are checking from a phone number not registered to the NIN, enrolment was never completed (a pre-enrolment slip is not an issued NIN), or a data error at enrolment. Retrieve the number via *346# from your registered line first.
How do I know if my NIN is linked to my SIM and BVN?
Confirm the SIM–NIN link with your telco, and check that the name and date of birth on your NIN and BVN match — banks increasingly require consistency. A valid NIN is not automatically linked everywhere it is needed.
My NIN shows the wrong name or date of birth. How do I fix it?
That requires a NIN modification, not just a re-check. Correct it before you need the NIN for a passport, licence or bank application, since those read the NIN as the source of truth. See the NIN modification guide.
I lost my NIN slip. Do I need a new NIN?
No. The number is permanent. You only need a reissue of the slip — see the NIN slip reissue page. The new slip carries the same NIN.
