How to Retrieve a Lost NIN in Nigeria (2026): USSD, App and No-Phone Options
Last updated: 1 November 2026 · By Naijatipsland Editorial Team · Editorial policy
Checked 1 November 2026. Lost your National Identification Number (NIN) slip, forgotten the 11 digits, or changed phones and can’t find the SMS NIMC sent you years ago? You are not alone, and you almost never need to re-enrol. Your NIN is permanent: once it is issued it stays attached to your fingerprints and face in the National Identity Management Commission (NIMC) database for life. Retrieval just means getting the number back to you.
This guide covers every official way to retrieve a lost NIN in Nigeria in 2026: the *346# USSD code, SMS, the NINAuth and MWS apps, and a walk-in visit to an NIMC enrolment centre. It also explains what to do if the phone number you registered with is gone, what each option costs, and how to avoid the agents who charge for “NIN look-ups”.
Quick answer: the fastest way to get your NIN back
If you still have the SIM card you used when you enrolled (or the number you later linked to your NIN), dial *346# and choose option 1 (NIN retrieval). Your NIN appears on screen within seconds, and you pay a small airtime charge of about ₦20 to ₦50 depending on your network. That’s it.
If that line is lost, go to the section on retrieving your NIN without your registered phone number below.
Method 1: Retrieve your NIN with the *346# USSD code
This is the method NIMC and the Nigerian Communications Commission (NCC) point people to first, because it works on any phone, needs no data, and runs on MTN, Airtel, Glo and 9mobile (T2).
- Insert the SIM card registered with your NIN, or linked to it during the NIN-SIM exercise.
- Dial *346#.
- Select 1 for NIN retrieval.
- Confirm the airtime deduction if prompted.
- Your 11-digit NIN is shown on screen and usually sent to you by SMS too. Write it down or screenshot it.
Common problems: “Number not linked” means that line was never attached to your NIN record; try another line you have used, or use Method 4. “Insufficient balance” means you need to recharge first. If the code times out, try again off-peak or restart the phone. You can find more network shortcodes in our list of USSD codes in Nigeria.
Method 2: Send an SMS to 346
Some networks also support a text-message route. From the registered line, send NIN to 346. The reply contains your NIN. The charge is similar to the USSD route. If you get no reply after a few minutes, use the USSD code instead; it is the more reliable channel.
Method 3: Use the NINAuth or NIMC MWS app
If you have a smartphone, NIMC’s apps give you more than the number. You can view your identity details and save a digital slip you can show when asked.
- NINAuth (ninauth.nimc.gov.ng and the NINAuth mobile app): NIMC’s newer identity-verification platform. In July 2026 NIMC announced that Nigerians can download their NIN slip free inside NINAuth. You log in with your phone number and a one-time password (OTP) sent to the number linked to your NIN.
- NIMC MWS (Mobile ID): the older “MWS: NIMC Personal ID” app on Google Play and the App Store. After setup with your number and OTP, it shows your NIN and lets you share a virtual NIN (VNIN) or QR code with banks and agencies instead of your real number.
Both apps depend on the same thing as USSD: you must still control the phone number linked to your NIN, because that is where the OTP goes. Download them only from the official app stores, and check that the publisher is the National Identity Management Commission.
Once you have your number, our guide on how to verify your NIN explains how to confirm the details on your record are correct.
How to retrieve your NIN without your registered phone number
This is where most people get stuck. If the SIM card you enrolled with is lost, stolen, blocked or deactivated, the USSD code and apps can’t reach you. You have two good options.
Option A: Recover the SIM first
If the number still exists on your network, the simplest fix is to get the same number back. Visit an MTN, Airtel, Glo or T2 customer service centre with valid ID and request a SIM replacement (SIM swap). Because the line is already tied to your NIN, the network verifies you against NIMC records. Once the replacement SIM works, dial *346#. Our step-by-step guide on how to retrieve a lost SIM card walks you through each network.
Option B: Visit an NIMC enrolment centre
If the number is gone for good, or you never linked a phone number at all, go to an NIMC enrolment centre (state and local government offices, plus many licensed front-end partners). Take:
- A valid photo ID if you have one (international passport, driver’s licence, voter’s card or an old NIN slip).
- Your old tracking ID or enrolment acknowledgement slip, if you still have it.
- Your new phone number, which you can ask to have linked to your record.
The officer will use your fingerprints to find your existing record and print your NIN slip. If you need a reprinted slip there is a re-issuance fee (see the fees table below). Do not let anyone enrol you again from scratch. A second enrolment creates a duplicate record, which NIMC treats as an offence and which can block your NIN later.
Can I find my NIN with my BVN, bank or name?
Not directly. Banks hold your NIN if you linked it, but they are not allowed to read it out to you on request, and there is no official “search NIN by name” service. Some fintech and bank apps show the last few digits of a linked NIN. That can confirm you are looking at the right record, but you still need one of the official methods above to get the full number. Our guide on checking your BVN and linked bank accounts covers what banks can and can’t show you.
What NIN retrieval and related services cost in 2026
NIMC published revised charges in May 2025. Retrieving your number is cheap; most costs come in when you need a new slip or a correction.
| Service | Official charge |
|---|---|
| NIN retrieval by *346# or SMS | About ₦20 to ₦50 airtime |
| NIN slip download in NINAuth | Free (announced July 2026) |
| Standard slip re-issuance at NIMC | ₦600 |
| Premium slip re-issuance | ₦3,500 |
| Modification of name or other fields | ₦2,000 |
| Date of birth change | ₦28,750 |
Fees can change, so check NIMC’s official channels before you pay. If your record has a spelling error or wrong date of birth, read our NIN modification and correction guide before you visit.
Avoid “NIN retrieval” agents and websites
Search for “retrieve NIN” and you’ll find WhatsApp sellers, roadside agents and websites offering to find anyone’s NIN for ₦1,000 to ₦5,000. Avoid them:
- They often get access through misused verification accounts, which means your data has already been exposed to people you don’t know.
- Many simply take the money and disappear.
- Handing your phone number, date of birth and photo to strangers makes SIM-swap fraud and bank fraud easier.
- The new NIMC Act 2026, signed in June 2026, brings tougher penalties for identity fraud and the unlawful use of other people’s identity data. Paying an agent to look up a NIN can drag you into that.
The official routes are cheap or free, so there is no reason to pay a middleman. If someone you know is “helping” you at a business centre, make sure they are a licensed NIMC partner and that you see the official screens.
Keep your NIN safe once you have it back
- Store it in two places: a photo of your slip in a secure, password-protected folder, and the number written somewhere at home.
- Use a virtual NIN (VNIN) from the app when a bank, telecom or employer asks for your NIN, so the real number isn’t copied everywhere.
- Keep your linked phone number active, and recharge it at least every few months so the network doesn’t recycle it.
- Link your NIN to your bank and SIMs while you have it handy. Our guide to linking your NIN to your bank account and SIM shows how.

Frequently asked questions
Is my NIN the same as my tracking ID?
No. The tracking ID is the temporary code on your enrolment acknowledgement slip. The NIN is the permanent 11-digit number issued afterwards. If you only have a tracking ID, an NIMC centre can use it to look up your NIN.
Can I retrieve my NIN from abroad?
Yes, if your Nigerian line still works on roaming you can dial *346#, or use NINAuth or the MWS app with the OTP. Otherwise, contact an NIMC diaspora enrolment partner in your country of residence.
I dialled *346# and it says my number isn’t linked. What now?
Try any other Nigerian number you have used for banking or SIM registration. If none works, visit an NIMC centre so your fingerprints can locate your record, and ask them to link your current number.
How long does retrieval take at an NIMC centre?
When the system is up, finding your record by fingerprints usually takes the same day. Queues vary, so arrive early and take a printed copy of any old enrolment documents.
Who do I contact if nothing works?
Use NIMC’s official channels: the contact details on nimc.gov.ng, the email info@nimc.gov.ng, or NIMC’s verified social media accounts. Never share your OTP with anyone who contacts you claiming to be from NIMC.
Disclaimer: this guide is for general information and is based on NIMC and NCC guidance available on 1 November 2026. Codes, apps and fees can change, so confirm with NIMC before paying for any service.
The quickest fix is still *346# from the line you registered with, and most people only get stuck when that SIM is gone. If you have retrieved a lost NIN recently, which method worked for you, and how long did it take?
