Baal Aadhaar is a blue-colored Aadhaar card issued to children below the age of 5 in India. Unlike adult Aadhaar, it does not require biometric data and is linked to one of the parents’ Aadhaar numbers. It serves as an official identity proof for accessing various child-related services, such as vaccinations, school admissions, and government welfare schemes. Once the child turns 5, biometric updates are necessary. Baal Aadhaar promotes early identity registration, helping ensure every child benefits from essential services from an early age.
