Strengthening Identity Verification in Nigeria’s Banking Sector
Nigeria’s financial regulator has taken significant steps to enhance the security and reliability of the Bank Verification Number (BVN) system, a critical tool for customer authentication across the banking sector. This move is aimed at addressing growing concerns over fraud and identity abuse while ensuring that the system remains effective in an increasingly digital environment.
The Central Bank of Nigeria (CBN) has introduced stricter rules governing BVN enrolment, data access, and transaction monitoring. These changes are designed to create a more robust framework that supports faster detection of suspicious activities without disrupting legitimate banking operations.
Key Revisions to the BVN Framework
One of the most notable changes is the introduction of a temporary watchlist for accounts linked to suspicious transactions. Financial institutions are now required to flag such BVNs for a maximum of 24 hours, during which the account holder must be contacted for clarification. This approach allows banks to respond quickly to potential fraud without immediately freezing accounts or escalating enforcement actions.
This shift towards real-time fraud response is expected to reduce wrongful account restrictions while maintaining vigilance against illicit transactions. Industry analysts believe this could help strike a balance between security and customer convenience.
Another key component of the revised framework is the CBN’s exclusive control over access to BVN databases. Under the new rules, only licensed financial institutions can access the database, although the regulator retains the discretion to grant access under exceptional circumstances.
Enhancing Customer Identity Rules
Beyond fraud monitoring, the revised framework introduces stricter rules governing who can enrol for a BVN and how customer data can be modified. The CBN has now limited BVN registration strictly to individuals aged 18 and above, aligning enrolment with legally recognized adulthood.
This change marks a departure from earlier practices where minors could be enrolled under certain conditions, often linked to guardians’ accounts. The aim is to eliminate grey areas in identity ownership and reduce vulnerabilities linked to proxy registrations.
Additionally, the apex bank has placed a cap on how often customers can change phone numbers linked to their BVN. Under the new rule, such changes will be allowed only once. Regulators believe frequent changes to contact details have been exploited by fraudsters to bypass authentication systems, especially in cases involving SIM swaps and unauthorized account access.
However, this restriction may introduce practical challenges for customers, particularly in a market where mobile number churn remains high. Telecom industry data shows that SIM replacement and multiple line ownership are common in Nigeria, raising questions about how banks will manage legitimate cases of number changes.
The Role of Technology and Collaboration
According to a recent report from PricewaterhouseCoopers, banks and telecommunications companies must deepen their collaboration and share intelligence to combat the growing threat of artificial intelligence-driven fraud. The professional services firm noted that the rapid adoption of AI is reshaping the fraud landscape in the telecommunications sector, enabling criminals to automate scams, impersonate victims through deepfake technologies, and scale fraudulent schemes with unprecedented speed.
Therefore, financial institutions are expected to update their customer service processes to accommodate the new rule, including stricter verification procedures before approving any modification.
The CBN has also reiterated its commitment to protecting customer rights, including privacy and data confidentiality, as part of the broader framework guiding BVN operations.
Expanding BVN Enrolment and Financial Inclusion
The regulatory overhaul comes at a time when BVN enrolment continues to expand, driven by increased financial inclusion efforts and digital banking adoption. Data from the Nigeria Inter-Bank Settlement System shows that the number of BVN-linked accounts has risen steadily in recent years.
As of December 2025, the BVN database reached 67.8 million registrations, expanding from 63.5 million in 2024 and 51.9 million in 2021. The data highlights consistent growth in the number of Nigerians integrated into the formal banking system.
The continued growth in BVN enrolment reflects broader structural changes in the financial sector, including the rise of fintech platforms, agency banking, and mobile money services.
Non-Resident BVN Initiative
At the same time, the CBN has taken steps to extend BVN coverage beyond Nigeria’s borders through the introduction of the Non-Resident BVN initiative. The NRBVN allows Nigerians in the diaspora to enrol remotely, enabling them to access financial services and participate more actively in the domestic economy.
The initiative is expected to support remittance flows and improve access to banking services for Nigerians living abroad. CBN Governor Olayemi Cardoso emphasized that the policy is part of a broader effort to strengthen formal remittance channels and deepen financial inclusion.
He added that the apex bank is targeting monthly remittance inflows of $1bn, supported by improved access and regulatory reforms.
Conclusion
As Nigeria’s financial system evolves, the BVN framework is expected to play a more central role in linking domestic and international financial flows while strengthening identity verification across the ecosystem. The combination of rising enrolment and tighter regulation signals a maturing financial system where identity verification is becoming more robust and standardized.
