SCAM ALERT

Common NIN and BVN Scams in Nigeria (and How to Avoid Them)

The tricks fraudsters use to steal your identity numbers, and the one rule that stops almost all of them.

Step by step

1. Recognise the baitMost scams arrive as an urgent call, SMS, WhatsApp or email claiming your NIN or BVN needs "urgent verification", "re-validation" or "linking" or your account will be blocked. Treat any such message as suspicious.
2. Never share codesDo not read out or type your OTP, card PIN, internet-banking password, or the answers to your security questions to anyone, even someone who claims to be from your bank, NIMC or the NCC.
3. Verify your own numbers safelyCheck your BVN yourself by dialling *565*0# from your registered phone (a small fee, around N20, may apply), and retrieve your NIN with *346#. These are self-service codes, so no agent is involved.
4. Go direct, not through linksInstead of clicking a link in a message, type the official address yourself: nimc.gov.ng for NIN and your bank's own website or app for BVN-linked matters. Confirm the padlock and exact spelling of the domain.
5. Hang up and call backIf a "bank" or "agency" calls, hang up and dial the number printed on your bank card or on the official website. Never continue a sensitive conversation on a call you did not start.
6. Report and warnIf you are targeted, tell your bank, report to the EFCC or the Nigeria Police cybercrime centre, and warn family so they do not fall for the same trick.

Why NIN and BVN scams work

Fraudsters know that your National Identification Number (NIN) and Bank Verification Number (BVN) sit at the centre of your financial and digital life in Nigeria. They do not usually need to break into any system. Instead, they trick you into handing over the missing piece, an OTP, a card PIN, a password, or a click on a fake link, that lets them take over an account. Almost every scam relies on urgency and fear: a threat that your account or SIM will be blocked “today” if you do not act.

The tricks you will see most

The common patterns are easy to spot once you know them. A caller claims to be from your bank’s “fraud desk” and needs an OTP to “reverse” a transaction. A text says your NIN must be “re-validated” through a link. A WhatsApp message offers to “link your NIN to your SIM” for a small fee. A form on a look-alike website asks for your BVN, date of birth and card details together. All of these mix a legitimate-sounding request with something a real agency would never ask for.

What real agencies actually do

NIMC, your bank, the NCC and the CBN communicate through official portals, verified branches and self-service codes, not through random links that demand secret codes. You can confirm your own details safely: learn how to check your BVN and how to check your NIN using the official USSD codes from your own registered line. If you are unsure why these numbers matter, our explainer on what a NIN is and why you need it gives the plain-English background.

Simple habits that keep you safe

Slow down when a message feels urgent, because urgency is the scammer’s main weapon. Type official web addresses yourself rather than clicking links. Never share an OTP, PIN or password with anyone. Do not use a third-party “agent” who offers to handle your NIN or BVN for you. If something feels wrong, it usually is, so pause and verify before you act. If you think a number of yours has already leaked, read what to do if your BVN or NIN is compromised.
