How to get a lost Aadhaar card without an Aadhaar number?

To get a lost Aadhaar card without an Aadhaar number, visit the official UIDAI website and use the Retrieve EID/UID service. Enter your full name and registered mobile number or email address to receive an OTP. Once verified, your Aadhaar number will be sent to your registered contact details via SMS. If you do not have a registered mobile number, you can visit the nearest Aadhaar Enrolment Centre with demographic details and provide biometrics for identity verification and retrieval, or call the UIDAI helpline at 1947 for assistance.
