How to delete IPO mandate?

You can delete the IPO mandate by canceling or withdrawing the IPO application. The UPI mandate for blocked funds generally gets removed after 24 hours of cancellation at the exchange's IPO bidding platform.

You can cancel the IPO application until 5 PM on the Offer Closing Date. Some banks offer this facility until 2 PM/ 3 PM. Once you submit the withdrawal request with the broker or bank, the request gets sent to the exchange for cancellation during the IPO bidding window.
