What is Demat Debit and Pledge Instruction (DDPI)?

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

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. Earlier, POA was collected for debiting the shares from the client's account. However, there have been instances of misuse by debiting shares without a sell trade, breaking POA clauses, trading on a client's account based on a POA, etc.

To prevent misuse of POA, SEBI, through this circular (WEB), has introduced DDPI, which limits debiting shares from a client’s account only if there’s a sell trade placed by the client. DDPI replaced POA on 19th November 2022.

While enabling DDPI at Zerodha is considered safe, as a broker, we would still advise clients to continue using eDIS since it gives users more control over their accounts. With eDIS, clients can specify which scrips to authorise and the quantities for each scrip. For instance, if a client holds 100 shares of Reliance and 500 shares of TATA Motors, they can authorise 30 shares of Reliance and 120 shares of TATA Motors for selling, ensuring that the broker cannot debit more than the authorised quantities.

On the other hand, if DDPI is submitted for an account, the broker has the ability to debit additional shares if there's an obligation to deliver. This obligation can arise from the client placing a sell order themselves or through a broker-induced trade in the client's account.
