Baal Aadhaar or Blue Aadhaar is issued by the Unique Identification Authority of India — UIDAI — to children in the age group of 0-5 years.
A Blue Aadhaar does not have biometric details of the children. The biometrics are updated once the child attains the age of 5.
Until then, a Blue Aadhaar is linked to one of the parents or guardians of the child.
