CBN Guidelines Reshape BVN Enrolment, Database Hits 68.6 Million

Nigeria’s Bank Verification Number (BVN) database expanded to 68.6 million in March, reflecting continued growth in the country’s financial identity system, even as the pace of new registrations begins to moderate following recent regulatory changes.

Latest figures released by Nigeria Inter-Bank Settlement System show that the database added 754,128 new enrolments between January and March, up from 67.8 million recorded at the end of last year.

While the increase signals sustained adoption of the BVN system, the first-quarter performance suggests a slower trajectory compared to previous years. In 2025 alone, over 4.3 million new BVNs were recorded, largely driven by the rollout of the Non-Resident BVN initiative, which enabled Nigerians in the diaspora to register remotely without physical presence.

By contrast, the sub-one-million increase in the first three months of this year indicates that enrolment momentum may be easing, raising the possibility of a lower overall tally by year-end if the trend persists.

Data from Nigeria Inter-Bank Settlement System also points to a significant gap between BVN registrations and total bank accounts in the system. As of March last year, Nigeria had more than 320 million active bank accounts, suggesting that millions of accounts remain either unlinked or consolidated under fewer BVNs, given that a single BVN can be tied to multiple accounts.

The evolving enrolment pattern comes amid new regulatory measures introduced by the Central Bank of Nigeria aimed at tightening identity verification and strengthening fraud control across the banking ecosystem.

Under the revised BVN framework, stricter rules now govern enrolment, data updates, and transaction monitoring. One of the most notable changes is the introduction of a minimum age requirement of 18 years for BVN registration, aligning the process with legally recognised age thresholds and potentially limiting new entries from younger demographics.

The updated guidelines also restrict customers to a one-time change of the phone number linked to their BVN, a move designed to curb identity manipulation and reduce fraud risks associated with frequent data alterations.

In addition, the apex bank has directed financial institutions to enhance real-time monitoring of suspicious transactions through a temporary watch-list mechanism. BVNs linked to questionable activities can now be flagged for up to 24 hours, during which the account holder is contacted to provide clarification before any further action is taken.

According to the regulator, this approach is intended to strike a balance between rapid fraud detection and customer protection, ensuring that legitimate users are not unduly penalised while maintaining the integrity of the financial system.

Analysts note that while these tighter controls may improve trust and security in the long term, they could also contribute to the short-term slowdown in enrolment figures, particularly as stricter verification requirements take effect.

Overall, the BVN system remains a critical pillar of Nigeria’s financial infrastructure, supporting identity management, reducing fraud, and enabling seamless banking operations. However, the interplay between regulatory tightening and enrolment growth will be closely watched in the coming months as stakeholders assess the broader impact on financial inclusion and system efficiency.
