The ‘Blue Aadhar card’ is valid only till the child's age is 5 years. You can also use the ID issued from a recognized school to get a blue Aadhar card.
If you don’t have a school ID, then the Aadhar card can also be made from the child's birth certificate or the discharge slip of the hospital.
After the child is 5 years old, the child's 'Biometric Aadhaar Data' will have to be updated.
How to apply?
To get the child Aadhar card, one has to apply in the same way as the Aadhar card of the elders is made. You have to fill a form available at the enrollment centre. In this, residence proof, relationship proof and birth certificate have to be attached. UIDAI accepts 31 types of identity proofs, 14 relationship proofs and 14 birth certificate documents.
