The Central Bank of Nigeria (CBN) has outlined 10 key changes to the Bank Verification Number (BVN) system, which will take effect from May 1, as part of renewed efforts to curb fraud and strengthen digital banking processes.
The apex bank said the updated guidelines will directly affect how customers access mobile banking services, switch devices, and manage their BVN details.
According to the CBN, the measures form part of a broader push to tighten security across Nigeria’s banking system and significantly reduce cases of fraud linked to digital transactions.
1. Mobile banking apps will be restricted to one device at a time.
2. Logging in on a new device will automatically log out the previous device.
3. Switching devices will require additional verification before access is granted.
4. Suspicious BVNs will be placed on a 24-hour watchlist.
5. Banks may temporarily restrict or freeze accounts linked to flagged BVNs.
6. Customers can only change their BVN-linked phone number once.
7. The rule targets SIM-swap fraud and unauthorised access.
8. Only individuals aged 18 and above can enrol for a BVN.
9. Minors must operate accounts under a guardian.
10. Transactions on newly activated devices will be capped at ₦20,000 within the first 24 hours.
The CBN emphasised that the new rules are designed to enhance security and protect customers from rising digital fraud risks.
