What is Demat Debit and Pledge Instruction (DDPI), and how to activate it online and offline?

Submitting DDPI is optional. Clients who have opened accounts online can use the CDSL TPIN to authorise the debit of securities. To learn more, see How to generate the CDSL TPIN required to authorise the CNC sell transactions?

Demat Debit and Pledge Instruction (DDPI) is a document that allows a broker to debit the securities from the client’s demat account and deliver them to the exchange. The client does not have to enter the CDSL T-PIN and OTP to sell shares once the DDPI is submitted.

SEBI introduced DDPI through this circular (WEB) , which limits debiting shares from a client’s account only if the client places a sell trade. DDPI replaced POA on November 19, 2022.
