You might receive such a message when tracking your PAN card status if there are any discrepancies in the PAN application that you submitted or if you haven’t attached all the necessary documentary proofs. In this case, the first thing that you need to do is contact the customer care of the issuing authority to get more details on why your application was rejected. The customer care executive will also help guide you on what to do next. You may be required to resubmit your PAN application once again after rectifying all the errors or mistakes.
