What Is CDSL TPIN Number

Let us consider an example, when you open a DEMAT account with Angel One, it authorises you to place buy and sell orders with BSE and NSE. And your account gets registered with CDSL. Both are independent authorities. When you place an order to ‘buy’, Angel One on your behalf virtually receives the shares and then shifts those to your DEMAT account with CDSL. Similarly, when you decide to sell, the shares are removed from your electronic account and transferred to the exchange.

So far, to sell on your behalf, broking houses have needed a POA (power of attorney) from the client. A power of attorney allows your stockbroker to take shares out of your account and provide them to the buyer. Many investors would sign this document without reading it; upon understanding this, a few stockbrokers started to misuse it. CDSL TPIN will eliminate POA from the system by allowing traders to give their consent through a uniquely generated code.

About e- DIS and its disadvantages

Clients who haven’t signed the POA were required to transact using an e-DIS (Electronic Delivery Instruction Slip). But there was one issue with this system. There were no ways for CDSL to confirm if the correct PIN was used before authorising the transaction. This new process of CDSL TPIN, applicable from June 1, 2020, will replace the old e-DIS system.

What is a CDSL TPIN?

CDSL TPIN stands for Central Depository Services Limited Transaction Personal Identification Number. It is a pin-based pre-authorization for selling stocks by CDSL. It is an improved and more technically advanced authorization process.

Features of TPIN 

  • TPIN is a 6-digit numerical pass code that enables CDSL Demat account holders to authorise their stockbrokers to debit shares and other securities from their Demat accounts.
  • TPIN is generated by CDSL and directly communicated to the client via their registered mobile number and email address. 
  • TPIN can be modified and reset at no cost.
  • TPIN is active for only one day and only for specific stocks.

Advantages of CDSL TPIN 

  • The entire Demat account process is paperless since TPIN eliminates the requirement for POA. Prior to this time, the POA had to be physically filled out, signed, and sent.
  • Investors can authorise the sale of shares online directly from their Demat account and obtain the TPIN directly from CDSL without the broker or depository participant becoming involved.
  • Clients can pre-authorize the selling of their stocks with a CDSL TPIN at the start of every trading day, avoiding the need to do so for each delivery sell order issued throughout the day.
  • The TPIN is handled by CDSL; therefore, the stockbroker is unable to use it improperly or manipulate it in any way that could harm an investor or trader.

When will I need a CDSL TPIN?

You’ll need to enter your TPIN when you place the first selling order of the day. When you click on ‘Authorise Now’, you’ll get redirected to the CDSL portal, where you need to insert a TPIN to authorise selling. You can also use the same PIN for the following:

  • Modify a sell order to get your intraday shares in your delivery account.
  • Convert a sell order from intraday to delivery.
  • You can also use the same TPIN to receive a margin benefit on your stocks.
