UIDAI lets cardholders generate a Virtual ID (VID): a random 16-digit number linked to your Aadhaar, which authenticators can use in place of your real 12-digit number.
Why it exists
The VID means your Aadhaar number does not need to be stored in every database you authenticate against. Because a VID is revocable, an agency can hold the VID without ever holding your permanent number.
Why it matters
- Two numbers, two roles: your real Aadhaar for official records, a rotating VID for daily life.
- Regenerating a VID leaves the old one dead, limiting the damage of a leak.
- It is a privacy layer, not a new identity.
Key takeaways
- VID = revocable 16-digit stand-in for your Aadhaar number.
- Use it for everyday checks; guard your real number.
- Regenerate immediately on any suspicion.
How to use it
- Generate a VID from the mAadhaar app or the UIDAI portal under "Aadhaar services".
- Use the VID for everyday authentications — OTP-based checks, eKYC, SIM updates — wherever a number is required.
- Revoke and regenerate any time you suspect misuse.
What you should do
- Default to the VID for daily authentications and reserve the real number for official use.
- Generate VIDs only from uidai.gov.in or mAadhaar.
- Revoke VIDs you no longer use so stale numbers do not float around.
