Why have I received an e-mail from CDSL saying PAN Verification Reversed?
This e-mail is sent when CDSL validates if your PAN from the Income Tax Database (ITD) is linked to Aadhaar. Please link PAN with Aadhaar at the earliest, or trading and investing will be disabled
after March 31st 2023,
as per this circular from NSE
(PDF)
and BSE
(WEB).
It can take up to 7 working days for the PAN to be updated in IT records.
To learn more, see
How do I link my PAN with Aadhaar?
See sample e-mail below:

You can ignore the e-mail if your PAN is already linked to Aadhar.
