If you use mobile banking, you’ll want to pay attention. From May 1, the Central Bank of Nigeria (CBN) is rolling out new BVN rules that could affect how you log in, switch devices, and even change your phone number.
The Central Bank of Nigeria (CBN) has announced a comprehensive overhaul of the Bank Verification Number (BVN) regulatory framework.
Set to take effect on May 1, 2026, the new guidelines introduce stringent restrictions on mobile banking, identity management, and transaction protocols, signaling a “zero-tolerance” approach to SIM-swap fraud and unauthorized account access.
Based on the upcoming regulatory changes from the Central Bank of Nigeria (CBN), here are the 10 key points regarding the new BVN and mobile banking rules:
1. Stricter BVN Enforcement (Effective May 1)
The CBN is implementing a more rigorous regulatory framework for the Bank Verification Number (BVN) to enhance financial security and minimize identity-related fraud across all Nigerian banks.
2. One Device Per Banking App
To prevent unauthorized access, customers are restricted to using their mobile banking application on only one device at a time. You can no longer remain logged in on multiple smartphones or tablets simultaneously.
3. Automatic Logout on New Devices
If you log into your banking app on a new smartphone, the session on your previous device will be instantly deactivated. This “device binding” ensures that only the most recently authorized hardware can access your funds.
4. Extra Verification for Device Swaps
Moving your banking profile to a new phone will no longer be a simple login. The migration will trigger Multi-Factor Authentication (MFA) and additional identity checks (such as liveness tests or OTPs) to confirm the switch is legitimate.
5. 24-Hour Fraud Watchlist
Any BVN flagged for suspicious or unusual activity will be placed on a temporary 24-hour watchlist. During this period, the bank will investigate the transaction and contact the account holder for clarification.
6. Temporary Account Restrictions
Banks now have the authority to restrict or freeze accounts immediately upon detecting suspicious patterns. This proactive measure aims to “halt” fraud in its tracks while verification is ongoing.
7. One-Time Phone Number Change
In a major shift, customers are now permitted only one phone number change in a lifetime for their BVN. This is intended to stop fraudsters from repeatedly swapping SIM cards to hijack account access.
8. Target on SIM-Swap Fraud
The rules specifically target SIM-swap scams, where criminals clone or redirect a user’s phone number to intercept bank OTPs. By making the linked phone number a permanent identifier, the CBN adds a layer of “identity consistency.”
9. Minimum Enrollment Age of 18
BVN enrollment is now strictly reserved for adults (18 years and older). Minors cannot have their own independent BVN; instead, their financial needs must be managed through accounts linked to a legal guardian.
10. ₦20,000 Limit on New Devices
For the first 24 hours after activating your banking app on a new device, transactions are capped at ₦20,000. This cooling-off period prevents “sweep-out” fraud, where a criminal gains access and immediately empties the account.
