What is TPIN, and do I need DDPI to sell shares in Alice Blue?

If you’re selling delivery holdings (shares in your Demat account), you need to authorise the debit of shares from your Demat account. For non-POA clients, this is usually done using a CDSL TPIN + OTP, and Alice Blue also highlights that TPIN is required for such clients when selling holdings.

DDPI (Demat Debit and Pledge Instruction) is an optional authorisation that, once enabled, generally reduces the need to enter TPIN/OTP every time you sell delivery shares (the exact flow depends on the broker’s process). Alice Blue’s community note says DDPI activation is done by submitting a DDPI request (via courier) and mentions ₹100 + GST as activation charges deducted from the ledger.
