How to get a duplicate Aadhaar card if lost?

To get a duplicate Aadhaar card if lost, visit the official UIDAI website and use the Retrieve Lost or Forgotten EID/UID service to recover your Aadhaar number. Once retrieved, you can download a digital e-Aadhaar for free, which is legally valid. Alternatively, you can order a durable Aadhaar PVC card through the portal for a fee of 50 rupees, inclusive of GST and speed post delivery. For offline assistance, visit a nearby Aadhaar Seva Kendra for a biometric-based printout.
