can pan card be used as address proof

No, a PAN card is generally not accepted as a primary proof of address (POA) for most official purposes in India. Its main function is as a Proof of Identity (POI) and a key financial document for tracking tax and high-value transactions. This is because the card itself does not contain the holder's residential address. For valid proof of address, Indian authorities typically require documents such as an Aadhaar card, Passport, Voter ID, Driving Licence, or recent utility bills.
