Aadhaar, the 12-digit unique identity number issued by the Unique Identification Authority of India (UIDAI), is a compulsory identity card. A number of government schemes require applicants to provide the Aadhaar number. Everyone can enroll for Aadhaar - even a newborn child, mentioned UIDAI in a tweet on it's official Twitter handle- @UIDAI. UIDAI has now also introduced a blue coloured 'Baal Aadhaar' card for children below the age of 5 years, another tweet mentioned. For enrolling a child for 'Baal Aadhaar' card, the child's birth certificate and the Aadhaar card number of one of the parents is required, said UIDAI in another tweet.
Biometrics is not developed for children before five years of age. According to UIDAI, a child's blue coloured Aadhaar data does not include biometric information like fingerprints and iris scan. Once the child crosses the age of five, biometrics should be updated, UIDAI further said.
