can another copy of my mother's aadhar card (first one is lost) which we get online by UIDAI number be submitted as a proof of identity and address to write her name with address in my UIDAI card
Yes you can submit that downloaded identify card,but it should not be masked one,it should be unmasked which in all details are mentioned instead of X ,take a colour print then it would be treated as a original aadhar card,it printed as photo copy then it would be as photocopy of original aadhar card
