Sometimes it becomes necessary to cancel the Aadhaar number when it is found that a resident has obtained it by submitting false biometrics or documents. It is a routine quality improvement process that UIDAI takes up regularly. 11/n— Aadhaar (@UIDAI) February 19, 2020
This is the best garbage UIDAi can come up with.... this also means it is possible to cancel one's Aadhar number.
Note that there is no provision for cancelling a deceased person's Aadhar number.
