How to get an Aadhaar number from a PAN card?

There is no official process to retrieve an Aadhaar number using only a PAN card. To find a lost Aadhaar number, visit the official UIDAI website and use the Retrieve EID/UID service. You must provide your registered mobile number or email ID to receive the Aadhaar number via SMS. Alternatively, you can call the UIDAI helpline at 1947 or visit a nearby Aadhaar Enrolment Centre with identity proof, such as your PAN card, for biometric-based retrieval.
