how to check my aadhaar card is used where

You can check where your Aadhaar has been used by viewing your Aadhaar Authentication History. This service is available on the official UIDAI website or through the mAadhaar App. You will need your Aadhaar number or Virtual ID and your registered mobile number to proceed. The history will show details of all authentication transactions from the last six months, including:

• Authentication Date and Time
• Type of Authentication (e.g., Biometric, OTP)
• Name of the User Agency (AUA)

This provides a secure way to monitor your Aadhaar's usage.
