How To Know Your Demat Account Number

A Demat Account is essential if you want to trade securities. With this account, you can invest in equities, currency, derivatives, commodities, and Mutual Funds. When you want to open a Demat Account, you need to register with a Depository Participant (DP). The Depository Participant will send you a 16-digit unique Demat account number once you have registered. This number allows you to trade in different financial markets. To trade securities, you will also need a trading account linked with your Demat account to buy/sell securities in exchanges such as NSE, MCX, and BSE.

What is a Depository Participant?

Depository Participants (DP) are the agent of a depository such as:

  • National Securities Depository Limited (NSDL) 

  • Central Depository Services Limited (CDSL) 


DP has the license to operate in the market. A depository issues this license under the provisions of The Depositories Act, 1996.

They have a unique DP ID assigned to them by CDSL or NSDL.

When new investors enter the stock market, they need to approach a depository participant to open a Demat account. Shares purchased by the investor are held in this account along with the depository participant. However, the investor remains the sole beneficial owner of the shares. The DP credits or debits finances whenever there is any buying or selling activity through this account.

How to know your Demat Account Number? 

Depending on your DP, you will receive the letter from the NSDL or the CDSL. The letter you receive will have a 16-digit Demat Account number. If you receive the letter from CDSL, the Account number is also known as the Beneficiary Owner ID (BO ID). The format of the number will vary from one Depository firm to the other.

If you receive the letter, the NDSL, the alphabet ‘IN’ will come before the 14-digit number, such as IN47368696536797. In the case of CDSL, it will just be in a number format, such as 1284653414677645.

In either case, the first eight digits of your Demat Account number will represent the DP ID. The latter eight digits represent the client ID. The client ID or the customer ID is unique to every trader.

Why is the Demat Account Number Significant?

The Demat Account number is a part of every transaction in the secondary market of India. The primary task of a Demat Account number is to remove the need of holding share certificates or other securities in a physical form. It substantially reduces the risk of theft and loss of securities. It also enables fast transfer of shares and securities between individuals.
