The UIDAI has been encouraging residents to upload Proof of Identity and Proof of Address (PoI/PoA) documents to revalidate their demographic details, especially if Aadhaar was issued 10 years back and never got updated. If there is a need to change demographic details (Name, Date of Birth, Address, etc), the residents can use regular online update service, or may visit nearest Aadhaar centre. In such cases normal charges will apply.
