The Central Bank of Nigeria (CBN) has announced a major update to the Bank Verification Number (BVN) system, with new rules set to take effect from May 1, 2026. These changes are designed to strengthen financial security, reduce fraud, and improve how Nigerians interact with mobile banking platforms.
If you use mobile banking apps, USSD services, or digital financial platforms, these new rules will directly affect how you access and manage your accounts.
Why the CBN is Introducing New BVN Rules
Over the years, Nigeria’s financial system has faced increasing threats from fraud, particularly through SIM swap attacks, unauthorized device access, and identity theft.
To address these risks, the CBN has introduced stricter BVN regulations aimed at:
- Enhancing account security
- Reducing fraud and identity theft
- Improving customer verification processes
- Protecting digital banking users
- Improved security but stricter access controls
- Less flexibility in switching devices
- More responsibility for safeguarding personal information
- Ensure your BVN details are accurate and up to date
- Secure your SIM card against unauthorized access
- Avoid frequent device switching
- Use trusted devices for banking transactions
- Enable biometric authentication where available
- Stricter login procedures
- Enhanced security layers
- Possible delays during verification processes
These changes represent one of the most significant updates to Nigeria’s banking system in recent years.
10 Key BVN Rule Changes Starting May 1, 2026
1. One Device Per Banking App
Customers will only be allowed to use their mobile banking app on one device at a time. This reduces the risk of unauthorized access across multiple devices.
2. Automatic Logout on New Device
If you log into your banking app on a new phone, the system will automatically log you out from your previous device.
3. Additional Verification When Switching Devices
Switching devices will now require extra authentication steps, such as OTP verification or biometric confirmation.
4. 24-Hour Fraud Watchlist
Any suspicious BVN activity will be flagged for 24 hours, during which the account may be closely monitored.
5. Temporary Account Restrictions
Banks now have the authority to temporarily freeze or restrict accounts if suspicious activity is detected.
6. One-Time Phone Number Change
Customers can only change their BVN-linked phone number once in a lifetime, making it critical to secure your SIM card.
7. SIM Swap Fraud Prevention
This rule specifically targets fraudsters who exploit SIM swaps to gain unauthorized access to bank accounts.
8. Minimum Age Requirement
Only individuals aged 18 years and above can enrol for BVN independently. Minors must operate accounts under a guardian.

When you log in on a new device, your transactions will be capped at ₦20,000 within the first 24 hours.
