BVN and Bank SMS Scams in Nigeria: How to Spot Fake 'Account Blocked' Messages
Fake bank messages are among the most common frauds in Nigeria. Scammers send SMS and WhatsApp messages impersonating GTBank, Access Bank, First Bank, Zenith, UBA or fintechs like OPay and Moniepoint, warning that your 'BVN has been suspended', your 'account is restricted' or your 'NIN is not linked'. You're told to call a number or click a link to 'reactivate'. The caller or fake site then collects your BVN, card details, internet banking login and OTP or token code, and empties your account through quick transfers and POS cash-outs.
Real Scam Message Examples
These are real examples of messages used in this type of scam. If you receive something similar, do not click any links.
Example 1
“Dear Customer, your GTBank account has been restricted due to BVN update. To avoid permanent deactivation, call our customer care on 0816XXXXXXX now.”
Example 2
“CBN ALERT: Your BVN has been suspended due to incomplete NIN linkage. All accounts linked to this BVN will be frozen in 24hrs. Reactivate: bvn-nibss-verify.com”
Example 3
“Access Bank: Your ATM card has been blocked due to suspicious activity. Reply with your card number, PIN and the OTP sent to you to unblock immediately.”
Warning Signs of a Fake Bank or BVN Message
- ⚠SMS says your BVN, account or ATM card has been 'blocked', 'suspended' or 'restricted' and gives a phone number to call
- ⚠It asks for your BVN, card PIN, internet banking password, OTP or hardware token code
- ⚠The link is a lookalike such as gtbank-bvn-update.com or accessbank-reactivate.net, not your bank's official domain
- ⚠The caller knows some of your details (name, bank) to seem credible and pressures you to act 'before 12 midnight'
- ⚠The message mentions CBN, NIBSS or 'BVN headquarters' as the sender
How Does This Scam Work?
- 1You receive an SMS, WhatsApp or robocall claiming a BVN, NIN or account problem
- 2You call the number or click the link and meet a friendly 'customer care agent' or a cloned bank page
- 3They ask for your BVN, card details, PIN, internet banking login or ask you to dial a USSD string they provide
- 4They then request the OTP or token code 'to complete the update' — actually authorising a transfer
- 5Money is sent to multiple accounts and withdrawn through POS agents within minutes
Legitimate vs Scam: How to Tell the Difference

| BVN issues | Resolved in person at your bank branch | 'Reactivate your BVN' through a link or phone call |
| Website | gtbank.com, accessbankplc.com, firstbanknigeria.com, zenithbank.com, ubagroup.com | gtbank-bvn-update.com, bvn-nibss-verify.com, accessbank-reactivate.net |

Can my BVN be blocked by SMS?
No. BVN issues are handled by your bank, usually at a branch. The CBN and NIBSS do not send SMS asking you to click a link or call a number to 'reactivate' your BVN.
Will my bank ever ask for my OTP or PIN?
Never. Nigerian banks and fintechs repeatedly state that staff will not ask for your PIN, OTP, token code or password. Anyone who asks is a fraudster.
I gave my OTP to someone who claimed to be my bank. What should I do?
Call your bank immediately to freeze the account and block your cards, change your internet banking password and PIN, and file a report with your bank and the police or EFCC. Quick action gives the bank a chance to place a hold on receiving accounts.
How do I report a scam SMS number in Nigeria?
Call the NCC's toll-free consumer line 622 to report fraudulent numbers, and also report to your mobile network. For money lost, report to your bank and the EFCC.
Why do scammers know my name and bank?
Data from leaks, previous scams or careless sharing is widely traded. Knowing your name or bank does not make a caller genuine — verify by calling your bank yourself.
