The Unique Identification Authority of India (UIDAI) on Tuesday (July 15, 2025) urged parents of children between the age of 5 and 7 to update their kids’ Aadhaar biometrics.

In the periodic reminder, the UIDAI said that the biometric update would be free of cost at enrolment centres, if done before children turned seven. After this period, the authority said it may cancel Aadhaar numbers issued to those who have not done the biometric update. A ₹100 fee applies if such an application is made after a child turns seven.

“Aadhaar with updated biometric facilitates ease of living and ensures seamless usage of Aadhaar in availing services such as school admissions, registering for entrance examinations, availing benefits of scholarships, DBT (Direct Benefit Transfer) schemes, etc wherever applicable,” the UIDAI said. “Parents/ guardians are advised to update biometrics of their children/wards in Aadhaar, on priority,” it added.

The Aadhaar issuer said it has started sending SMS messages to the mobile numbers registered in the Aadhaar of such children for completing the MBU exercise. “The fingerprints and iris biometrics of a child are not captured for Aadhaar enrolment below the age of five because these are not mature at that age,” the UIDAI said.
