The Central Bank of Nigeria has unveiled a comprehensive overhaul of the Bank Verification Number framework, introducing ten major changes designed to combat electronic fraud and identity theft across the nation’s financial system. The new guidelines, which take effect on 1 May 2026, represent a significant tightening of digital banking access controls and personal data management protocols.
The updated policy introduces a “Single Device Locking” requirement for mobile banking applications, tethering each customer’s banking app to one specific mobile device. Logging into an account from a new smartphone will automatically deactivate access on the previous device, a measure specifically aimed at preventing unauthorised account takeovers and limiting the window for fraudulent activity.
Brandspur Banking News Desk reports that customers switching to new devices will face a 24-hour transaction limit capped at ₦20,000 during the transition period, providing an additional layer of protection while the system validates the device change. The apex bank has also placed stringent restrictions on personal data updates, with customers now permitted to change the phone number linked to their BVN only once in their lifetime.
The “one-time” phone number change policy is specifically targeted at curbing SIM-swap fraud, which has emerged as a primary tool for cybercriminals seeking to intercept one-time passwords and drain victim accounts. Demographic eligibility requirements have also been tightened, with the CBN setting a minimum age of 18 years for independent BVN enrollment.
Minors will no longer be eligible for standalone BVNs and must instead have their accounts linked to a legal guardian’s profile. This ensures that every account operated by a minor remains under direct adult supervision within the regulatory net, closing a previous loophole that had been exploited in some fraud cases.
The CBN is additionally implementing a 24-hour automated fraud watchlist system, under which any BVN associated with suspicious transaction patterns or flagged activities will be restricted immediately for a cooling-off period. This 24-hour restriction window allows financial institutions to verify the legitimacy of transactions before permanent damage occurs, reinforcing the overall security architecture of the Nigerian digital economy.
The new BVN framework represents one of the most significant regulatory interventions in Nigeria’s banking sector since the introduction of the BVN system itself, reflecting the CBN’s determination to stay ahead of evolving fraud techniques. Financial institutions have been directed to begin immediate preparations for full implementation of all ten changes by the 1 May 2026 deadline.
