UIDAI completed 2 crore mandatory biometric updates for school children. The drive, free for ages 5-17 until September 2026, requires a visit to an enrolment centre.
The Unique Identification Authority of India has completed more than 2 crore mandatory biometric updates for school children, the Ministry of Electronics and Information Technology said in a release. The drive, launched in September 2025, covered more than 1.56 lakh schools across the country.
UIDAI worked with state and union territory education departments to set up biometric update camps at schools. The camps let children add fingerprints, iris scans, and a photograph to their Aadhaar records.
Children under five are enrolled using only demographic details and a photo. Their biometrics are not captured at that stage. As they grow, those details need to be collected and refreshed. The mandatory biometric update, or MBU, does exactly that.
The update is free for children aged 5 to 17 years until 30 September 2026, the release said. UIDAI had waived fees for the 7–15 age group from 1 October 2025 for one year. The 5–7 and 15–17 groups were already free.
Keeping children's biometrics updated reduces authentication problems in school and higher education, the authority said. Outdated biometrics can cause trouble when Aadhaar is needed for exams, scholarships, or government schemes.
Parents cannot complete the process online. They must take the child to an Aadhaar enrolment centre. The first MBU is due after the child turns five. The second update is due after they turn 15.
