To find your TPIN, check your registered email or mobile SMS from CDSL, which you received when your Demat account was opened.
A TPIN (Transaction Personal Identification Number) is a crucial 6-digit code provided by CDSL (Central Depository Services Limited) that allows you to authenticate your sale transactions in your Demat account. It ensures secure and authorized execution of your sell orders.
Where to Look for Your Existing TPIN
The most direct way to "know" or retrieve your existing TPIN is by referring to the initial communications you received:
- Email from CDSL: When you first opened your Demat account, CDSL would have sent you an email containing your TPIN. Search your inbox, including spam or junk folders, for emails from "CDSL" or with keywords like "TPIN," "Demat Account," or "Transaction PIN."
- SMS from CDSL: Similarly, a text message containing your TPIN would have been sent to your registered mobile number upon Demat account opening. Check your message history for any SMS from CDSL.
Tip: Look for messages or emails dated around the time you opened your Demat account or activated online trading services.
What to Do If You Cannot Find Your TPIN
If you are unable to locate the original email or SMS containing your TPIN, you generally cannot retrieve the exact "old" number. Instead, the process involves generating a new TPIN, which will then replace any previous one.
Steps to Generate a New TPIN:
If your existing TPIN is lost or forgotten, follow these simple steps to create a new one:
- Visit the CDSL TPIN Generation Portal: Navigate to the official CDSL website or the specific TPIN generation page provided by your stockbroker. (For example, you can often find a link like CDSL TPIN Generation on CDSL's website, though specific URLs may vary or be embedded within your broker's platform.)
- Enter Your Details: You will typically be prompted to enter your:
- BO ID (Beneficiary Owner Identification Number): This is your 16-digit Demat account number.
- PAN (Permanent Account Number): Your 10-character PAN card number.
- Receive OTP: An OTP (One Time Password) will be sent to your mobile number and email ID registered with your Demat account for verification.
- Set New TPIN: After successfully verifying the OTP, you will be able to set a new 6-digit TPIN of your choice. This new TPIN will instantly become active and replace any previously existing TPIN.
