Child Aadhaar Biometric Update: Parents Should Complete Mandatory Update at Ages 5 and 15, Check Process
Parents whose children have crossed the ages of 5 or 15 should pay attention to an important Aadhaar requirement. The Unique Identification Authority of India (UIDAI) requires children's biometric information to be updated at specific stages because physical features such as fingerprints and facial appearance change as they grow.
The process is known as the Mandatory Biometric Update (MBU). The first mandatory update becomes relevant after a child turns five, while another biometric update is required after reaching the prescribed age around 15.
Parents should not confuse this with a completely online Aadhaar update. While an appointment can be booked online where the facility is available, the child's fingerprints, iris scans and photograph have to be captured physically at an Aadhaar enrolment or update centre.
Here's what parents need to know about Baal Aadhaar, biometric updates, fees and the process for completing the requirement.
Why Do Children Need an Aadhaar Biometric Update at Age 5?
Aadhaar enrolment for a child below five works differently from enrolment for an older person.
When a young child is enrolled, the child's biometric details such as fingerprints and iris scans are not initially captured in the same manner as those of older Aadhaar holders. A facial photograph is taken and the child's Aadhaar is linked according to UIDAI's prescribed enrolment process.
Aadhaar issued to children below five is commonly referred to as Baal Aadhaar and is recognisable by its blue colour.
Once the child reaches five years of age, biometric information needs to be captured. This generally includes fingerprints, iris scans and an updated facial photograph.
Why Is Another Update Needed Around Age 15?
The biometric information recorded during childhood may change considerably as a person grows.
For this reason, UIDAI requires another Mandatory Biometric Update after the child reaches the prescribed age around 15. The fresh biometric capture helps ensure that the Aadhaar record reflects the individual's more mature biometric characteristics.
During this process, the child's fingerprints, iris information and photograph are captured again.
Parents should therefore not assume that completing the update after age five permanently completes all childhood Aadhaar requirements.
Can the Child Aadhaar Biometric Update Be Done Online?
The entire biometric update cannot be completed from home.
Fingerprints and iris scans require authorised biometric equipment, so the child must physically visit an Aadhaar enrolment or update centre.
However, parents can use UIDAI's online facilities to check relevant Aadhaar services and, where available, schedule an appointment before visiting a centre.
Booking an appointment in advance can make the visit more convenient and may reduce waiting time.
How to Complete the Mandatory Biometric Update
Parents or guardians should first identify a convenient Aadhaar enrolment or update centre and check whether an appointment can be booked in advance.
On the scheduled date, take the child to the centre along with the required Aadhaar and supporting information.
At the centre, the authorised operator will carry out the biometric capture required for the child's age. This can include fingerprints, iris scans and a new photograph.
Before completing the request, carefully review the information displayed by the operator and make sure there are no errors in the child's demographic details.
After the update request is submitted, keep the acknowledgement or update request information safely until the process is completed.
What Documents Should Parents Carry?
Document requirements can depend on the type of update being requested and the child's Aadhaar record.
Parents should carry the child's Aadhaar details and the appropriate original supporting documents prescribed by UIDAI. The parent or guardian may also need relevant Aadhaar or identity documentation depending on the service being performed.
It is advisable to check UIDAI's latest document requirements before visiting the centre rather than relying on an old list circulating on social media.
If demographic details such as name, address or date of birth also need correction, additional supporting documents may be required.
Is the Mandatory Biometric Update Free?
UIDAI has specific rules governing charges for Aadhaar enrolment and updates, including Mandatory Biometric Updates for children.
Parents should check the latest UIDAI fee structure applicable to the child's age and the timing of the update. This is particularly important because the fee treatment can depend on whether the mandatory update is being completed within the prescribed age window.
If any payment is required at an Aadhaar centre, ask for an official acknowledgement or receipt.
Parents should avoid paying agents who claim that they can bypass the biometric process or complete the update without the child visiting an authorised centre.
What Happens If the Biometric Update Is Delayed?
Ignoring the Mandatory Biometric Update can eventually create difficulties in using Aadhaar authentication.
Since Aadhaar may be required or used as identity documentation for various services, authentication problems can become inconvenient when a child needs Aadhaar for an eligible service or verification process.
Parents should therefore complete the required biometric updates within UIDAI's prescribed timelines rather than waiting until Aadhaar is urgently needed.
However, claims that a child's school admission, scholarship, passport or examination application will automatically become invalid merely because an update is pending should be treated cautiously. The rules of the particular institution or service should always be checked separately.
How to Find a Nearby Aadhaar Centre
Parents can use UIDAI's official services to locate Aadhaar centres and check available appointment facilities.
Choose a suitable centre, review the available service options and book a slot if appointment booking is offered for that location.
When visiting the centre, take the child along because biometric information cannot be captured remotely.
Arriving with the correct documents can help prevent the need for a second visit.
Don't Trust Fake Aadhaar Update Links
Messages warning that a child's Aadhaar will be immediately blocked unless a payment is made through a link should be treated with suspicion.
Cybercriminals frequently exploit government-service deadlines to obtain Aadhaar numbers, banking details and OTPs.
Parents should never disclose an OTP, UPI PIN, banking password or card PIN to someone claiming to be an Aadhaar representative.
Aadhaar-related services should be accessed through UIDAI's authorised platforms or recognised Aadhaar centres.
What Parents Should Do Now
If your child has crossed one of the ages at which UIDAI requires a Mandatory Biometric Update, check the Aadhaar record and arrange the required update without unnecessary delay.
Remember that booking or locating a centre can be done online, but biometric capture itself requires the child to visit an authorised Aadhaar centre.
The update ensures that fingerprints, iris data and the child's latest photograph are appropriately recorded as the child grows.
Before visiting, parents should verify the latest UIDAI rules regarding the eligible age window, fees and documents. Completing the process at the appropriate time can help ensure smoother Aadhaar authentication when the child needs to use the identity document in the future.
