Know the importance of TPIN in a Demat account

A Demat account, also known as a dematerialized account, is a type of account that allows investors to hold their shares and securities in an electronic format, suited for the internet age, rather than in physical certificates. You can open a demat account with depository participants (DPs), who are authorised by the National Securities Depository Limited (NSDL) or Central Depository Services Limited (CDSL) to offer Demat services to investors. As an investor, it is necessary to research well about the depository participant, evaluate their features, and demat app, and go through the demat account charges before opening a demat account with them. 

That said, in this article, we will be learning about one of the key features of a demat account. Now a demat account has several features like its cost-effectiveness, convenience, instant transactions, etc. However, the key feature discussed in this article regarding security. That feature is the Transaction Personal Identification Number (TPIN), which is used for added security. It is a security measure provided by your DP once you open a demat account. 

TPIN and Its Importance 

As an investor, you don’t want unauthorised parties getting access to your demat account and selling your shares. A TPIN helps with that and scenarios of misuse like those. A TPIN is a unique password that is used to authenticate a demat account holder before they can perform certain transactions, such as buying or selling shares. This is an added security measure that helps to ensure that only authorised individuals are able to access and make changes to a demat account.

Your depository participant gives you your Transaction Personal Identification Number (TPIN) after you open a demat account. This TPIN is used to confirm your identity before any transactions are carried out in your demat account. You will be required to enter your TPIN every time you want to perform a transaction, such as buying or selling shares. Without a valid TPIN, the transaction cannot be completed.

It is important to note that the TPIN is only valid for a single transaction and expires once the transaction is completed. This means that you will have to enter your TPIN every time you want to perform a transaction. This added layer of security helps to prevent unauthorised access to your demat account and ensures that only you can execute buying and selling transactions.

It is essential to keep your TPIN confidential and not share it with anyone. If your TPIN is compromised, it can be misused to perform unauthorised transactions. In such cases, you should immediately contact your DP and request a new TPIN. In the event you forget your TPIN, most DPs provide the “forgot TPIN” or “generate new TPIN” option. In case you click on a similar option, you will receive a new TPIN on your registered email ID. 

How to Get Your TPIN

As mentioned earlier, you get your TPIN after you open a demat account, so let’s see how you can get yourself a demat account. The process to open a demat account is relatively simple, although it requires some documentation, which is nowadays accepted in the digital format. First, you carefully choose a DP, authorised by the depositories to provide demat account services based on the services they provide, their demat app, and the demat account charges. Then you proceed to visit the DP’s website or download their demat app.

Once you have landed on their website or downloaded their mobile app, click the prompt to open a demat account. You fill out the account opening form by providing some basic details like your name, DOB, PAN number, address, etc. After that you will need to provide the necessary documents, like your PAN and Passport, to support the details you provided. Once the KYC (Know Your Customer) process is completed, your DP will verify your details and provide you with demat account login credentials via the registered email ID. 

Besides the login credentials, your depository, either the CDSL or the NSDL, will provide you your TPIN on your registered email ID. 


In conclusion, your TPIN is an important feature of your demat account that provides an added layer of security. It ensures that only authorised individuals are able to access and make changes to your demat account, and helps to prevent unauthorised access and transactions. Therefore, it is important to keep your TPIN confidential and not to share it with anyone. In the event you think an unauthorised party got access to your TPIN, quickly report the suspicious activity to your DP.
