UIDAI Mandates Biometric Update for Children Aged 7; Non-Compliance May Lead to Aadhaar Deactivation

The Unique Identification Authority of India (UIDAI) has issued a crucial reminder for all parents and guardians complete your child’s Mandatory Biometric Update (MBU) once they turn 7, or risk Aadhaar deactivation.

What Is the Mandatory Biometric Update (MBU)?

When a child is first enrolled for Aadhaar, typically before the age of 5, biometric data like fingerprints, iris scans, and facial photographs are not collected because these physical traits are still developing. However, once the child reaches the age of 5, a biometric update becomes mandatory. This update captures the child’s fingerprint, iris scan, and a fresh photograph.

But UIDAI has now emphasised another critical MBU requirement when a child turns 7 years old. Despite existing rules, many parents have yet to complete this important step potentially putting their child’s Aadhaar number at risk of deactivation.

Access to Key Services

An Aadhaar with up-to-date biometric data is essential for smooth access to a range of services, including:

• School admissions
• Applying for scholarships
• Registering for entrance exams
• Receiving government benefits and DBT schemes

With millions of Aadhaar holders in Uttar Pradesh alone, UIDAI’s regional office in Lucknow recently launched a large-scale campaign to reach out to parents of over 4.6 crore children. SMS alerts are being sent to registered mobile numbers, urging parents to complete the MBU process.

What is the Cost of the Biometric Update?

• Free if done between ages 5 and 7
• ₹100 if done after 7 years

Where to Update Aadhaar Biometrics?

The update can be completed at any Aadhaar Seva Kendra or designated Aadhaar enrolment centre. Just bring your child, along with their Aadhaar card and your identity proof.

By completing the biometric update on time, parents can help avoid any disruption and keep their child's Aadhaar active and functional. UIDAI’s guidelines aim to streamline access to welfare benefits and public services making timely compliance both necessary and beneficial.
