Aadhaar is a unique 12-digit identity number issued by the Unique Identification Authority of India (UIDAI) on behalf of the Government of India. Aadhaar is for individuals, therefore a number issued to an individual shall not be reassigned to any other individual. Aadhaar is based on biometric and demographic data.
