Hi Abhishek,
Your Zerodha PIN (ZPIN) is your personal identification for placing orders through our Call & Trade desk and for raising support queries. You can now reset your ZPIN through the Q-Backoffice under Profile (You can login to Q-Backoffice using your Kite Login ID and password).
You will receive the ZPIN to your registered Email ID and Phone Number.
You are required to enter the last 4 digits of your Client Id and your ZPIN in the IVR to connect to a Support Agent
For example- If your Client ID is DF0185 and ZPIN is 0007, you need to enter 01850007 in the IVR.
