In order to use any kind of financial services or products In India. It is mandatory to open a Demat account. Same is the procedure for the share market too. To be able to purchase, sell, track and analyse shares or a group of stock, one has to create a Demat account assigned by a Depository Participant (DP).
Once you open a Demat account, you will receive a Demat account number, which contains a BO (Beneficial Owner) ID or a client ID. The BO ID is a unique ID that identifies different clients, but it is not the same as a client ID. So, what is the client ID in a Demat account? Scroll below to get the answer to your question.
What Is Client ID in Demat Account?
A client ID is a unique combination of 8 numerical digits assigned by their DP at the time of account creation. An investor uses his/her client ID to perform all kinds of tasks in the stock market, from buying and selling to analysing. The number is designed by the DPs using their own formula, and it is not influenced by the depositories themselves.
A Demat account number is a combination of 16-digit numeric codes that every account holder has. This number is a combination of two IDs.
- Client ID
- DP ID
Difference between Client ID and DP ID
Both DP ID and Client ID in Demat account together form the Demat account number. Here are the key differences between Client ID and DP ID:
| Client ID | DP ID |
| This part of the account number identifies the account holder or the individual investor) | This part of the account number identifies the Depository Participant (bank, broker, etc.) through which the individual has created his/her account. |
| The Depository Participants (ie-bank, broker, etc.) assign the client ID. | The depositories (i.e., NSDL and CDSL) assign the DP ID. |
| It identifies the client itself. | It recognises the DP in the depository system. |
Hence, a Demat account number identifies the client and the DP together through whom the client has created a new account.
