The Aadhar card is an unique identification number issued by the UIDAI to establish a unique identification number for every individual. Aadhar is actually a 12 digit number and not a card given to every individual who apply to get their Aadhar number.
Aadhar is meant to identify any individual including children. As it is for individuals every member in the family will get a different number. Residence address information, photograph, iris scan and fingerprints are collected and stored in a data base.
The Aadhar number will be valid for life and need not be renewed or changed or updated. The Aadhar number is given free of cost. This number can be used as your identity proof while opening a bank account, making bookings online, when you apply for your passport and anywhere where an identity proof is required.
Apply for your Aadhar number immediately.
