CBN Tightens BVN Rules — What It Means for Bank Customers from May 1st

Nigeria’s central bank is introducing new rules around the Bank Verification Number (BVN), a move that could change how millions of people use digital banking services.

The Central Bank of Nigeria (CBN) says the measures, set to take effect from May 1, are aimed at strengthening security, reducing fraud and improving control over the country’s financial system.

But for many Nigerians, the real question is simple: what exactly will change?

Under the new guidelines, individuals will only be allowed to change the phone number linked to their BVN once in a lifetime, a step designed to reduce identity manipulation and SIM-related fraud.

The CBN is also introducing a fraud watchlist system, where accounts linked to suspicious transactions could face temporary restrictions for up to 24 hours while checks are carried out.

In addition, customers using a new device for digital banking may face temporary limits. Transactions could be capped at ₦20,000 within the first 24 hours, as part of efforts to verify unusual activity and prevent unauthorized access.

BVN registration will now be restricted to individuals aged 18 and above, reinforcing identity verification standards across the banking system.

Another key change focuses on data protection, with access to BVN information limited strictly to licensed financial institutions, aimed at reducing misuse of sensitive personal data.

While regulators say these measures will improve trust and security, they may also bring short-term inconvenience.

Customers with outdated or inconsistent BVN details could experience delays or restrictions when carrying out transactions.

Analysts say the new rules reflect a broader shift toward tighter digital financial regulation in Nigeria, especially as online and mobile banking continue to grow rapidly.

As the rollout date approaches, banks are expected to notify customers and encourage them to verify their details to avoid disruptions.

For now, the message is clear: stronger security is coming and it may change how Nigerians interact with their bank accounts, at least in the short term.
