What is it?
# UIDAI’s VID will be a 16-digit, randomly-generated number that can be used for authentication instead of the original Aadhaar number
# VID will be temporary and it will not be possible to derive Aadhaar number from VID.
How is it protected?
# VID can be generated only by the Aadhaar number holder.
# VID, by design being temporary, cannot be used by agencies for de-duplication.
# VID is revocable and can be replaced by a new one by Aadhaar number holder after the minimum validity period set by UIDAI policy
# Last digit of the VID is the checksum using ‘Verhoeff’ algorithm as in Aadhaar number. There will be only one active and valid VID for an Aadhaar number at any given time
# The “Verhoeff” algorithm is a checksum formula for error detection developed by the Dutch mathematician Jacobus Verhoeff and was first published in 1969.
What can be done with VID?
# Aadhaar number holder can use VID in lieu of Aadhaar number whenever authentication or KYC services are performed.
# Authentication may be performed using VID in a manner similar to using Aadhaar number.
What are the options available?
# User will be able to generate, retrieve in case they forget, and replace their VIDs with a new number via UIDAI’s resident portal, Aadhaar Enrollment Center and mAaadhaar mobile application
