You usually need proof of residence, such as a ration card, voter ID, or utility bills showing your address.
Proof of identity, like Aadhaar or PAN, and proof of the required duration of residence are also asked.
In some states a school or college certificate and an affidavit are needed.
Apply through your state’s revenue department portal or the Tehsildar’s office.
