The Central Bank of Nigeria (CBN) has announced significant updates to the Bank Verification Number (BVN) Operations and Watch-List Framework, aimed at strengthening fraud prevention and enhancing the integrity of Nigeria’s financial system.
The new measures, contained in a circular issued on 12 March 2026, will take effect from 1 May 2026 and will apply to banks, financial institutions, payment service providers, and other licensed operators within the Nigerian financial ecosystem.
The revised framework introduces tighter verification procedures, stricter identity controls, and new monitoring mechanisms designed to reduce identity theft, financial fraud, and unauthorized access to banking systems.
Understanding the BVN System
The Bank Verification Number (BVN) is a unique biometric identification number issued to bank customers in Nigeria. It links an individual’s biometric data—such as fingerprints and facial recognition—to their banking records across financial institutions.
The BVN system was originally introduced by the Central Bank of Nigeria in collaboration with the Nigeria Inter-Bank Settlement System to strengthen Know-Your-Customer (KYC) compliance and curb fraudulent banking activities. Over the years, the BVN framework has become a core pillar of Nigeria’s financial identity infrastructure, connecting customer identity across banks, payment platforms, and other financial services.
Key New BVN Regulations Effective 1 May 2026
The updated framework introduces several important operational and security changes.
- Temporary Fraud Watchlist Mechanism
- Financial institutions are now required to establish a temporary 24-hour watchlist for BVNs associated with suspicious or potentially fraudulent transactions.
Under this rule:
A BVN flagged for suspicious activity may be placed on a temporary monitoring list for 24 hours.
During this period, banks will conduct enhanced verification procedures.
The objective is to prevent fraudulent transfers while investigations are conducted.
This mechanism allows banks to respond quickly to suspected fraud without immediately imposing permanent restrictions on the affected customer. Other measures include;
1. Lifetime Limit on Phone Number Changes
To reduce identity manipulation and account takeover fraud, the CBN has introduced a lifetime restriction on BVN-linked phone number changes.
Key provisions include:
A BVN holder may change the registered phone number only once in their lifetime.
Any change request must undergo strict identity verification procedures.
Financial institutions must maintain audit trails for such changes.
The measure is intended to curb fraud schemes where criminals frequently alter registered phone numbers to bypass banking security systems.
2. Minimum Age Requirement for BVN Enrolment
The revised framework also introduces a minimum age requirement for BVN enrolment.
Only individuals aged 18 years and above are eligible to enrol in the BVN system.
This rule aligns BVN enrolment with legal financial responsibility and regulatory compliance requirements.
The change is designed to ensure that BVN-linked accounts correspond with individuals legally capable of holding financial obligations.
3. Restricted Access to the BVN Database
Access to the BVN database has been tightened significantly.
Under the new rules:
Only CBN-licensed financial institutions are permitted to access the BVN database.
Unauthorized entities, third-party agents, or unlicensed operators are prohibited from accessing BVN records.
Institutions must comply with enhanced data protection and privacy protocols.
This measure strengthens the confidentiality and integrity of the national financial identity system.
Additional Digital Banking Security Measures
Alongside the BVN framework update, the Central Bank of Nigeria has introduced complementary measures to further secure Nigeria’s digital banking environment, such as;
1. Mobile Banking Device Restriction
Banking applications will now be restricted to one active device per customer account at any given time. This control reduces the risk of unauthorized access through multiple devices and strengthens account security.
2. Transaction Limits for Newly Activated Accounts
To mitigate fraud risks associated with newly created or newly activated accounts: A ₦20,000 transaction limit will apply during the first 24 hours of account activation or mobile app registration.
This temporary restriction allows banks to monitor early account activity and detect potential fraudulent behaviours.
3.Real-Time Identity Verification
Financial institutions must now conduct real-time identity validation against national identity databases when:
Opening a new bank account
Reactivating a dormant account
Updating sensitive customer information
Verification will be conducted using data from the BVN system and the National Identification Number (NIN) database.
Implications for Banks and Customers
The new BVN regulations represent a significant step in Nigeria’s ongoing effort to strengthen financial sector security.
Financial institutions, banks, and payment service providers will need to:
Upgrade fraud monitoring systems
Implement real-time verification protocols
Improve customer identity management processes
Strengthen data protection controls
Banks ‘ customers should expect:
More stringent identity verification procedures
Stricter controls on phone number updates
Enhanced monitoring of suspicious transactions
These measures are intended to protect customers from identity theft and unauthorized banking activities.
Strengthening Nigeria’s Financial System
The updated BVN framework reflects the Central Bank of Nigeria’s continued commitment to improving financial security, protecting consumers, and enhancing the resilience of Nigeria’s banking infrastructure.
As digital banking adoption continues to grow rapidly across Nigeria, regulatory safeguards such as these are critical in maintaining trust and stability within the financial system. By tightening identity verification, restricting unauthorized access, and improving fraud monitoring, the new framework is expected to reduce fraudulent activities within the banking sector significantly.
