What is the process for a child’s Mandatory Biometric Update (MBU)?

The uidai aadhaar card regulations mandate that children must update their biometrics twice: first at age 5 and again at age 15. This is known as a Mandatory Biometric Update (MBU) and is essential to keep the my aadhar profile active and accurate as the child's physical features change. Unlike demographic updates, MBU must be done in person at an Aadhaar Seva Kendra, as it requires capturing fresh fingerprints, iris scans, and a photograph. In 2025, UIDAI has waived the charges for the first MBU for children aged 7-15 to encourage compliance.

To book a slot for your child, visit the My Aadhaar UIDAI portal and use the appointment booking tool. You will need the child's original Aadhaar Card and the parent's ID for verification. Failure to complete the MBU can lead to the deactivation of the child's Aadhaar, affecting school admissions or scholarship disbursements. At Myadhaaruidai.com, we provide a dedicated checklist for parents to ensure a smooth visit to the center and a guide on how to track the post-update status using the enrollment slip.
