Nigeria's National Identity Management Commission uses AI-driven 1:N biometric matching to stop duplicate enrolments in the National Identification Number database, letting 121 million citizens verify themselves once and reuse that identity for SIM cards, banking and welfare.

Context
Nigeria's National Identity Management Commission (NIMC) runs an Automated Biometric Identification System performing real-time 1:N fingerprint and facial matching on applications for the National Identification Number (NIN), rejecting enrolments that match biometrics already in the register.
Objectives
The aim is once-only biometric identity: preventing duplicate NIN enrolments so a single verified identity can be reused as reference identity for bank accounts, SIM-card registration and federal welfare enrolment.
Activities
NIMC has issued NINs since 2012, reaching about 121 million by June 2025; in February 2024 it signed a three-year contract with IDEMIA Smart Identity to upgrade ABIS capacity from 100 million to 250 million records and support up to one million biometric searches per day, funded in part by roughly $430 million from the World Bank (IDA), AFD and EIB.
Results
Implementation has faced service disruptions during SIM-NIN linkage mandate rollouts and system capacity overages, and NIMC still needs approximately 59 million additional enrolments by December 2026 to meet coverage targets.
Conclusions
NIMC's de-duplication model has scaled to over a hundred million enrolments and underpins a single national ID reused across sectors, but transparency and governance scores remain low and full population coverage is not yet reached.
Implementation
Indicative cost
Very high (> €5M) — ~$430 million financed via World Bank IDA, AFD and EIB; 2024 IDEMIA contract upgraded capacity from 100 million to 250 million records.
Time to results
Long (> 3 years) — Operating since 2012, ongoing enrolment drive targeting full coverage by December 2026.
Staffing & skills
NIMC enrolment centre agents, IDEMIA technical/system contractor
Conditions for success
real-time 1:N biometric deduplication at enrolment
sustained capacity investment (250 million record upgrade)
integration as reference ID across banking, telecom and welfare
Common failure modes
service disruptions during SIM-NIN linkage mandate rollouts
system capacity overages
enrolment backlog (59 million still needed for full coverage)
