eDIS Authorization Process

The financial landscape in India has undergone a significant transformation in recent years, with the Securities and Exchange Board of India (SEBI) introducing measures to enhance investor security. One such innovation is eDIS (Electronic Delivery Instruction Slip), a digital mechanism that allows demat account holders to authorize share delivery for sell transactions without requiring a Physical Power of Attorney (POA). As of 2026, eDIS is the standard authorization method across CDSL (Central Depository Services Limited) and NSDL (National Securities Depository Limited). This guide provides a detailed walkthrough of the eDIS authorization process, including TPIN generation, OTP-based consent, and the differences between eDIS on NSDL and CDSL.

eDIS, short for Electronic Delivery Instruction Slip, is a SEBI-mandated digital facility that enables demat account holders to authorize the delivery of securities for sell transactions. Before eDIS was introduced, investors were required to submit a signed POA (Power of Attorney) to their broker or depository participant, a physical process that was prone to misuse.

With eDIS, the authorization process is entirely digital, requiring a 6-digit TPIN (for CDSL accounts) or MPIN (for NSDL accounts) along with an OTP sent to the registered mobile number and email. This dual authentication method was made mandatory by SEBI through its 2021 circular, ensuring enhanced security and transparency.

eDIS works exclusively for securities held in the linked demat account, meaning that investors cannot authorize transactions for securities they do not own. As of 2026, eDIS remains the universal standard for delivery-based sell transactions across all Indian brokers.

The eDIS mechanism simplifies the authorization process while providing robust security. Here is how it works:

1. Initiating the Sell Order: When you place a delivery sell order, your broker redirects you to the eDIS gateway based on your depository (CDSL or NSDL).
2. Account Verification: Enter your 16-digit BOID (Beneficial Owner Identification Number) and PAN on the gateway.
3. Authentication: Provide your 6-digit TPIN (CDSL) or MPIN (NSDL) and enter the OTP sent to your registered mobile number and email address.
4. Authorization: Confirm the scrip name, ISIN, and quantity of shares to be sold. You can authorize either full or partial quantities, as long as they are within your demat balance.
5. Validation: The depository validates the instruction and processes the transaction.
6. Security Alerts: NSDL sends an SMS to your registered mobile number after every debit, while CDSL authorizations are valid until the market closes at 3:30 PM IST on the day of authorization.

This process ensures that transactions are completed securely and efficiently, typically within 60 seconds.

For demat accounts linked to CDSL, follow these steps to authorize transactions via eDIS:

1. Log in to Your Broker’s Portal: Access your account and navigate to the Holdings section.
2. Select Stock and Quantity: Choose the stock and the quantity you wish to sell.
3. Click ‘Authorize’: You will be redirected to the CDSL eDIS portal.
4. Enter BOID and PAN: Input your 16-digit BOID and PAN.
5. Complete Captcha: Solve the captcha and proceed.
6. Receive OTP: An OTP will be sent to your registered mobile and email. Enter the OTP on the portal.
7. Enter TPIN: Provide your 6-digit TPIN. If you do not have a TPIN, click ‘Generate TPIN’ to receive one on your registered contacts.
8. Confirm Details: Verify the scrip name, ISIN, and quantity of shares to be sold.
9. Submit Authorization: Click ‘Authorize’ to complete the transaction.

Note: If you enter an incorrect TPIN three consecutive times, your TPIN will be locked. You can generate a new TPIN via the CDSL portal, which will be activated within 6 minutes.

For demat accounts linked to NSDL, the process is slightly different as it uses MPIN instead of TPIN. Follow these steps:

1. Initiate Sell Order: Place a sell order through your broker’s platform. You will be redirected to the NSDL Demat Gateway or IDeAS portal.
2. Enter Account Details: Provide your 16-digit NSDL demat account number and PAN.
3. Receive OTP: NSDL sends an OTP to your registered mobile and email (e-DIS consent SMS).
4. Enter MPIN: Input your 6-digit MPIN. If you do not have an MPIN, set one up via the NSDL IDeAS portal.
5. Confirm Details: Select the securities and quantity for authorization.
6. Submit Authorization: NSDL validates and processes the transaction.

The MPIN is permanent until you reset it, and NSDL sends a post-debit SMS for added transparency.

Setting up a TPIN for your CDSL account is straightforward. Follow these steps:

• System-Generated TPIN:
  • Visit edis.cdslindia.com and click ‘Generate TPIN’.
  • Provide your BOID and PAN, complete the captcha, and submit.
  • An OTP will be sent to your registered mobile/email. Enter the OTP to verify.
  • The system will send the TPIN to your registered contacts within minutes.
• Custom TPIN:
  • Visit edis.cdslindia.com/home/changepin.
  • Enter your BOID and PAN, complete OTP verification, and set a new 6-digit TPIN.

Important Notes:

• The TPIN is numeric, permanent until reset, and can be reused for multiple authorization sessions.
• If your TPIN gets locked after three incorrect entries, generate a fresh TPIN via the portal.
• Never share your TPIN with anyone, including brokers or sub-brokers.

The e-DIS consent SMS is an essential part of SEBI’s dual-factor authentication requirement. Here is what you need to know:

• Purpose: The SMS contains a 6-digit OTP sent by CDSL or NSDL when you initiate a sell authorization.
• Details: It includes the OTP, validity period (usually 10 minutes), and transaction details such as the scrip name and ISIN.
• Security Alerts: NSDL sends a second SMS after securities are debited as a real-time activity alert.

What to Do If You Receive an Unsolicited SMS:

If you receive an e-DIS consent SMS without initiating a sell order, this could indicate fraudulent activity. Immediately contact your broker and update your TPIN or MPIN to secure your account.

eDIS offers several advantages over traditional POA, including:

1. No Physical Documentation: Eliminates the need for signed POA forms.
2. Transaction-Level Control: Allows investors to authorize each transaction individually.
3. Real-Time Alerts: Provides transparency through OTP consent and post-debit SMS notifications.
4. Simplified Setup: TPIN/MPIN requires only a one-time setup.
5. Compliance: Fully aligned with SEBI regulations, ensuring secure and transparent transactions.

Here are some common challenges faced during eDIS authorization and their solutions:

• OTP Not Received: Ensure your registered mobile/email is active and updated with your depository participant.
• Locked TPIN: If your TPIN is locked after three incorrect entries, generate a fresh TPIN via the CDSL portal.
• Authorization Page Not Loading: Use Chrome or Firefox browsers, clear cookies, and disable ad-blockers.
• Incorrect BOID: Verify your 16-digit BOID in your demat account details.
• Authorization Expiry: Re-authorize your sell order if it carries over to the next trading day.
• Scrip Not Showing: Ensure the settlement process for recently purchased shares is complete before initiating eDIS.

The eDIS authorization process is a secure, SEBI-mandated mechanism that empowers investors to authorize share deliveries digitally without requiring a Physical POA. By utilizing TPIN or MPIN combined with OTP authentication, investors can complete transactions swiftly and securely while maintaining full control over their demat accounts. Whether you use CDSL or NSDL, the eDIS process is streamlined, transparent, and compliant with regulatory standards as of 2026.

For a seamless trading experience, open a demat account with a reliable broker integrated with CDSL and NSDL gateways. Always consult a SEBI-registered advisor for tailored investment advice to make informed financial decisions.
