Agree with learned Expert Vaibhav ji,
A minor can apply for pan number but all things to be done by guardians as suggested by Expert...
But after attaining majority,
You need to fill up a form called "Request for new PAN card or/and changes or correction in PAN data" which is meant for corrections of data in PAN card and issue a fresh PAN card after corrections and insertion of the Signature of the Child with updated photo...
So, the Pan card becomes the ID proof with his own Signature and with the updated photo...
