PIB TrackerTwo crore children's fingerprints updated, through their schools
UIDAI's drive linked Aadhaar to the UDISE+ school database to find which children were due a mandatory biometric update, then ran camps in over 1.56 lakh schools — free for ages 5 to 17 until 30 September.
What happened
- UIDAI completed over 2 crore Mandatory Biometric Updates for school children.
- It was enabled by integration with the UDISE+ education database.
- The drive has covered over 1.56 lakh schools since September 2025.
- Aadhaar for children under five captures no fingerprints or iris — those biometrics are still developing.
- MBU is required at 5 and again at 15, and is free for ages 5-17 until 30 September 2026.
For Prelims
- MBU: Mandatory Biometric Update — required when a child turns 5 and again at 15.
- Why under-5 enrolment differs: only demographic data and a photograph are captured; fingerprints and iris are still developing.
- Bal Aadhaar: the blue Aadhaar issued to children below five.
- UDISE+: the Unified District Information System for Education Plus — the school database UIDAI integrated with to identify due children.
- Scale: over 2 crore updates across more than 1.56 lakh schools since September 2025.
- Free window: ages 5-17 until 30 September 2026.
- Why it matters: without MBU, authentication can fail for school admission, scholarships and benefit transfer.
- Legal basis: the Aadhaar Act, 2016; UIDAI is the statutory authority.
For UPSC: A good digital-identity administration card. Use it for Aadhaar lifecycle management and authentication failure as an exclusion risk, database interoperability in service delivery, and taking services to beneficiaries rather than the reverse.
What it is NOT: This is a biometric update drive, not new enrolment — and the school route reaches enrolled children, which by construction misses those out of school, who are also the most likely to need Aadhaar for entitlements.

Anchor
An identity that fails authentication at the moment of need is worse than no identity at all — which is what an un-updated child Aadhaar becomes.
Substantiation (data)
Over 2 crore updates across more than 1.56 lakh schools since September 2025, free for ages 5-17 until 30 September 2026.
Exemplification
Integration with UDISE+ converted a dispersed, unknown population into a school-by-school list of children actually due an update.
Problematisation
Delivery through schools structurally excludes out-of-school children — precisely the group whose entitlements depend most on a working Aadhaar.
Way-forward
Extend camps through Anganwadi centres and Common Service Centres to reach out-of-school children, and publish authentication-failure rates by age band.
Position
Digital identity is only inclusive if the update mechanism reaches the people the system already struggles to see.
