As per the NSE circular your PAN has to be linked to the Aadhaar before the 30th June 2023.
From the month of July, 2023 PAN Card not linked with Aadhaar will be considered as invalid for the purpose of trading in the Securities Market. It is therefore better to ensure that the PAN - Aadhaar linking is done before the due date.
