Only one PAN card can be used for one application. No matter how many different savings account details you might utilize, if there is the same PAN number in more than two applications, then all of them would be revoked.
Some certain guidelines and rules are laid down by the SEBI for traders and investors to apply for an IPO. These are strict rules to ensure that fluidity and transparency is achieved amongst all the people looking to invest in the particular IPO. Amongst the many rules, the most important one is that only one application can be submitted by a trader or investor for one IPO.
You cannot apply multiple applications for that same IPO as one PAN card is valid for one IPO application. No matter how many times you might apply for an IPO application using the same PAN number, all the applications would be canceled. You can change all the details, but then your PAN card number wouldn’t change, which would still lead to your application's rejection.
