Check details of your Aadhaar Card online and print a soft copy as well. Users can get the card online by providing details such as their enrollment numbers, date, time, resident name and pin code. The Aadhaar application process begins by booking an appointment online. This service allows Indian residents to schedule a visit to an Aadhaar Enrolment Centre at their convenience. During the appointment, biometric data (fingerprints, iris scan, and photograph) and demographic details are collected. This information is then processed, and the applicant is issued a unique 12-digit Aadhaar number. UIDAI is mandated to issue an easily verifiable 12 digit random number as Unique Identity - Aadhaar to all Residents of India.
