The Central Bank of Nigeria (CBN) has officially implemented a strict new regulatory framework for Bank Verification Number (BVN) operations, which took effect on May 1, 2026. These rules are designed to aggressively target digital fraud, particularly SIM-swap scams and unauthorized account takeovers. [1, 2, 3, 4]
Key BVN Rule Changes
- One-Time Phone Number Update: You can now only change the phone number linked to your BVN once in your lifetime.
- This measure aims to stop identity manipulation and secure authentication channels like OTPs.
- Customers are urged to link their BVN to a secure, long-term number, ideally the one registered with their National Identification Number (NIN).
- One Device per Banking App: Mobile banking applications are now restricted to one device at a time per user.
- Logging in on a new device will automatically log you out of the previous one.
- Switching to a new device triggers a ₦20,000 transaction cap for the first 24 hours to limit potential losses from compromised accounts.
- 24-Hour Fraud Watchlist: Any BVN flagged for suspicious activity will be placed on a temporary 24-hour watchlist.
- Affected accounts may be temporarily frozen while the bank contacts the holder for verification.
- Age Restriction: BVN enrollment is now strictly limited to individuals aged 18 years and above.
- Minors can no longer hold standalone BVNs and must operate accounts through guardian-linked arrangements.
- Restricted Data Access: Access to the BVN database is now limited exclusively to CBN-licensed financial institutions to prevent data leaks. [2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]
Actionable Steps for Customers
- Confirm Current Details: Verify exactly which phone number is currently linked to your BVN before attempting your single permitted change.
- Secure Authentication: Prepare for stricter identity verification—such as biometrics or facial recognition—when switching mobile devices or updating records.
- Official Guidance: You can view the full implications of these rules in the NIBSS guide on new BVN regulations or watch the detailed explainer from YouTube to ensure your account remains compliant. [4, 8, 15
