By 2024 the NIN had become the most important number in a Nigerian's life — and the single point of failure in the country's identity stack. To open a bank account, you needed a BVN, which now required a NIN. To get the BVN, you needed a NIN. To swap a SIM, port a number, register for JAMB, apply for a passport, collect an NSITF benefit, receive a federal palliative, register a vehicle, or vote in the 2023 general election (where INEC accepted the NIN slip as one of the recognised IDs at polling units), you needed a NIN.
The operational consequences were immediate. When NIMC's backend went down — as it repeatedly did across 2022 and 2023, sometimes for days — enrolment, verification, bank onboarding, telecoms activation and passport processing stopped together. The Commission's monthly verification API serves an estimated 400 million transactions today; outages cascade through every regulated sector that has wired itself into the register. In March 2024, the Federal Government raised NIN enrolment and modification fees by between 75% and 500%, then partially reversed the increase after public outcry — the first sign that the state had discovered the new register could be priced as a revenue source.
The data-protection picture caught up only afterwards. The Nigeria Data Protection Act, 2023, signed by President Tinubu in June 2023, created the Nigeria Data Protection Commission and gave Nigerians, for the first time, statutory rights over their personal data — including the right to know which agencies query their NIN, on what authority, and how often. Investigations by *Paradigm Initiative*, *Premium Times* and *FIJ* in 2023–2024 documented online marketplaces selling NIN slips and verification look-ups for as little as ₦100 a record. NIMC sued some of the platforms. The leaks did not stop.
The arithmetic by mid-2024 was stark: roughly 115 million Nigerians enrolled, an estimated 80–100 million still off the register (mostly under-18s and rural northerners), every major federal service downstream of it, no comprehensive audit trail of who had queried what, and an enabling Act seventeen years old that had never anticipated a register this large or this central. That was the system the Sixth Amendment Bill of 2026 — signed today — was written to reorganise.
