eDIS (electronic Delivery Instruction Slip) is how you authorise CDSL to debit shares from your ATS demat account when you sell — using a TPIN issued to you by CDSL and an OTP, instead of a paper slip or a Power of Attorney. For the full background on TPIN, see our TPIN, e-DIS & pre-authorisation guide.

How to authorise a share sale with eDIS
- Place a sell order (or start the authorisation) on the ATS trading platform.
- You are redirected to the CDSL eDIS page showing the shares (ISIN and quantity) to be authorised.
- Enter your 6-digit CDSL TPIN.
- Enter the OTP sent to the mobile number and email registered with your demat account.
- Once CDSL confirms the authorisation, your sell order can proceed and the shares are debited on settlement.
Never share your TPIN or OTP. No one at ATS or CDSL will ever ask for them. If someone does, report it — see Account Security & Fraud Prevention.
Per-trade authorisation vs pre-authorisation
| Per-trade authorisation | Pre-authorisation | |
|---|---|---|
| When | At the time you place the sell order | Before you trade, for shares you plan to sell |
| How | TPIN + OTP on the CDSL page | TPIN + OTP on the CDSL page |
| Validity | As shown on the CDSL authorisation screen | As shown on the CDSL authorisation screen |
| Can it be revoked? | Yes — see below | Yes — see below |
How do I revoke the authorisation I've given for eDIS transactions?
You can request the revocation of shares already authorised for debit through the eDIS process using either of the following methods:
- Email Request — send an email to compliance@adityatrading.com requesting eDIS authorisation revocation.
- Support Ticket — create a support ticket with the subject "eDIS Authorisation Revocation Request."
Include these details: the ISIN and the date of authorisation for which the revocation needs to be carried out. If you still need help, Create Ticket.
Common eDIS problems and what to do
| Problem | What to do |
|---|---|
| Forgot TPIN | Regenerate it from the CDSL page — the new TPIN replaces the old one. See the TPIN guide. |
| TPIN rejected | Make sure you are entering the CDSL TPIN, not your trading password. |
| OTP not received | The OTP goes to the mobile/email registered with your demat account. If those are outdated, update them with ATS. |
| Sell order rejected for missing authorisation | Complete the eDIS authorisation for that ISIN and quantity, then place the order again. |
| Anything else | Create a support ticket or contact us. |
