Trust gets people to sign up for a digital identity system, but whether the system actually works depends on something entirely different. Evidence from 210 countries suggests Nigeria should focus hard on that second part.
NINAuth and the standards coming from the National Information Technology Development Agency both represent genuine progress. The identity management commission's app lets citizens control who accesses their National Identification Number, while NITDA's upcoming standards will require encryption, biometric checks and auditable logs on every identity lookup.
The real question isn't whether these rules exist. It's whether anyone enforces them.
But there's a bigger constraint that gets far less attention. A white paper published in May by IN Groupe examined digital identity systems across 210 countries using 17 maturity measures from University College London data.
Only a third of countries worldwide have reached full maturity, it found.
The truly mature systems share one thing. It isn't cutting-edge biometrics or comprehensive legal codes.
It's routine, everyday use across banks, telecoms companies, hospitals and government agencies. That's the only variable that cleanly separates working systems from those that stall.
Nigeria ranks in the top tier alongside Kenya, Ethiopia and South Africa, which tells the researchers something important: governance choices matter more than how wealthy a country is. But how did Nigeria get there?
The answer wasn't fancy fingerprint readers. It was two hard decisions that wove identity into the economy's core infrastructure.
In December 2020, the government made the NIN mandatory for SIM registration. Enrolments jumped from 46.4 million in January 2021 to more than 94 million within two years.
Then came the Central Bank's requirement in April 2024: bank accounts now had to link to both the Bank Verification Number and the NIN. The BVN database hit 67.8 million by the end of 2025, while NIN enrolments reached roughly 127 million.
The World Bank wants 180 million enrolled by the end of 2026 under the $430 million ID4D programme, which is co-financed with the French Development Agency and the European Investment Bank.
The results speak loudly. Digital payment fraud losses plummeted by 51 percent in a single year, dropping from N52.26 billion in 2024 to N25.85 billion in 2025, according to the Nigeria Inter-Bank Settlement System.
That dramatic decline didn't come from awareness campaigns or trust-building exercises. It came from making the system impossible to ignore in daily transactions.
Nigeria's next challenge is keeping momentum on that second front. Citizens are enrolling.
The harder work is making sure every financial institution, hospital and government office actually uses what they've built.
