A ‘Baal Aadhaar’ is a special Aadhaar document issued by the Unique Identification Authority of India (UIDAI) for all children below the age of five years. This is a special document, recognizable by its blue colour. The document provides children with a unique 12-digit identification number that can be utilized for school admissions, passport applications, hospital registrations, government welfare schemes and other Aadhaar-related services.
Unlike with regular Aadhaar cards, children under five years of age are not required to provide fingerprints or iris scans, as their biometrics are still developing.
Hence, the child’s Aadhaar is linked to the of one parent or legal guardian, for identity verification. Once the child turns five, the first Mandatory Biometric Update (MBU) must be completed, followed by another at age 15.

Mandatory biometric update: What all parents should know
‘Baal Aadhaar’ issued to children below five does not contain biometric information.
During this process, iris scans, fresh photos and fingerprints of parents or legal guardians are captured. Then a second update is compulsory after the child turns 15.
Currently, both mandatory biometric updates are provided free of cost if completed within the prescribed age period. In 2026, UIDAI also launched a nationwide awareness campaign involving schools to encourage parents to complete these updates on time.
