How to avoid entering CDSL TPIN and OTP every time you sell on Zerodha

Sat, 20 Jun 2026 00:00:00 +0000

To stop entering a CDSL TPIN and a one-time password on every Zerodha sell, activate the Demat Debit and Pledge Instruction , or DDPI, from Console . The TPIN-and-OTP prompt appears because your demat runs on eDIS , where CDSL makes you authorise each debit individually and the authorisation expires the same day. DDPI is a one-time standing mandate that lets your broker debit sold securities straight to the exchange, so the per-sell authorisation step disappears.

How to revoke a POA or DDPI mapped to your Zerodha account

Sat, 20 Jun 2026 00:00:00 +0000

To revoke a POA or a DDPI mapped to your Zerodha account, fill the Revocation of Power of Attorney-DDPI form, then either e-sign it and raise a support ticket, or courier the signed form to Zerodha’s Bengaluru support centre. The same form covers both a legacy POA and a DDPI. Processing takes up to 5 working days from the date Zerodha receives the form, after which the account reverts to CDSL eDIS, so every delivery sell then needs a TPIN and OTP.

How to sell holdings without POA or DDPI on Zerodha

Sat, 20 Jun 2026 00:00:00 +0000

If you hold neither a power of attorney mandate nor a DDPI on your Zerodha account, you can still sell your holdings; you authorise each demat debit yourself through CDSL eDIS, the electronic delivery instruction route. You place the sell order, a CDSL authorisation window opens, you enter your 6-digit CDSL TPIN and a one-time password, and the debit is approved for that trading day. This is the default route for every account opened online that has not signed a DDPI.

Why Zerodha discontinued the demat POA and moved to DDPI

Sat, 20 Jun 2026 00:00:00 +0000

The broker demat power of attorney (POA) is the authorisation a client once gave a stockbroker to debit securities from the client’s demat account and deliver them to the exchange, which SEBI discontinued for new clients and replaced with the Demat Debit and Pledge Instruction (DDPI) through circular SEBI/HO/MIRSD/DoP/P/CIR/2022/44, dated 4 April 2022, effective for new clients from 1 September 2022. Zerodha adopted the DDPI for new clients from 19 November 2022, while leaving every POA submitted earlier valid until revoked.

CDSL TPIN regime (eDIS)

Wed, 20 May 2026 00:00:00 +0000

The CDSL TPIN (Transaction PIN) regime, also known as eDIS (electronic Delivery Instruction Slip), is the authorisation framework that allowed CDSL demat-account holders to authorise sell orders electronically using a one-time PIN, replacing the physical DIS slip system. It was the dominant authorisation mechanism for retail sell orders for several years before being progressively replaced by the CDSL block mechanism .

What TPIN is

TPIN is a 6-digit PIN issued to the demat account holder by CDSL. It serves as the holder’s electronic signature for delivery authorisation.

Zerodha eDIS T-PIN OTP

The Zerodha eDIS T-PIN + OTP flow is the dual-factor authorisation used (historically and in residual cases) for selling CDSL-held shares without a physical DIS slip. The flow combines the holder’s CDSL T-PIN (a 6-digit transaction PIN) with a one-time password (OTP) sent to the registered mobile, providing strong authentication.

How to sign DDPI on Zerodha

Tue, 12 May 2026 00:00:00 +0000

This guide explains how to sign the Demat Debit and Pledge Instruction (DDPI) on Zerodha, what it replaces, and the practical benefit for equity delivery sell orders.

Prerequisites

An active Zerodha demat and trading account with the equity delivery segment enabled.
Access to the Aadhaar-registered mobile number for the OTP required during e-sign.
Understanding of what the DDPI authorises: it is a standing instruction that permits Zerodha to debit (transfer out) securities from the demat account solely for the purpose of settling sell orders that the account holder has placed. The DDPI does not give Zerodha blanket authority over the demat account; the scope is limited to settlement of client-initiated sell transactions.
DDPI signing is optional. Without it, every sell order on an equity delivery holding requires the account holder to separately authorise the debit via CDSL’s TPIN (a 6-digit PIN) or the CDSL eDIS system at the time of the trade. DDPI signing eliminates this per-trade authorisation step.

Step-by-step procedure

Step 1: Understand the DDPI and what it replaces

Prior to the DDPI framework introduced by SEBI in 2022, brokers used a Power of Attorney (PoA) document that gave them broad authority over the client’s demat account, including pledging and off-market transfers in some cases. Concerns about PoA misuse led SEBI to introduce the DDPI as a more restricted instrument.
