The depository participant is usually the broker with whom you have your demat & trading account.DP ID, or Depository Participant Identification, is a crucial element in the world of stock market investing. It is like your Demat account’s unique address in the vast neighbourhood of the stock market.
This article explores key aspects of what is DP in Demat account along with steps on how to find DP ID and Client ID in a simple way.
Before we dive deeper into DP ID, let’s understand the meaning of DP. The DP full form in stock market context is Depository Participant. Think of a DP as an intermediary between you and the depository where your demat account is maintained. They are financial institutions like brokerage houses that act on your behalf to hold and transfer your securities.
So, when you open a demat account in India, you are associating yourself with a DP. They are the ones who manage your electronic records of shareholdings and process your transactions, acting as a personal assistant for all your stock market business.
Now that you know what DP is in the share market,it is time to understand what DP ID means.
Now, let’s get to the heart of the matter. What is DP ID in a Demat account? See, your demat account number consists of a 16-digit code, which can be numeric or alphanumeric, depending on the depository. Of these 16 digits,, the first eight digits signify the unique digit identification number assigned to your Depository Participant, also called DP ID. Think of it as your DP’s fingerprint in the stock market system. Every time you make a transaction, this ID helps identify which DP is handling it. The last eight digits signify the unique identification number the depository assigned to you, also called the beneficiary ID or BO ID.

Let’s make this concept more concrete with examples for both CDSL Demat account and NSDL Demat account
Your DP ID ensures that your transactions are accurately processed and your securities are located where they should be.
In India, there are two main depositories, i.e., National Securities Depository Limited (NSDL) and Central Depository Services Limited (CDSL). Both use DP IDs, but there are some key differences you should know about.
First, let’s talk about DP ID in NSDL. NSDL DP IDs always start with ‘IN’, followed by a unique 6 digit number. For example, a NSDL DP ID might look like ‘IN301549’.
On the other hand, CDSL doesn’t use a separate DP ID. Instead, it combines the DP ID and client ID into a single 16 digit number. The first 8 digits represent the DP, while the last 8 are your unique client ID.
So, if someone asks you about your DP ID and client ID, the answer will depend on whether you are with NSDL or CDSL. With NSDL, DP ID and client ID will have separate numbers for each. With CDSL, it is all rolled into one 16 digit number.
Your DP ID is not the same as your Demat account number. Your DP ID is like your neighbourhood’s pincode, while your Demat account number is your specific house number within that neighbourhood.

You don’t actually get a 16 digit DP ID. What you are referring to is likely the combination of DP ID and client ID used in CDSL accounts. When you open a Demat account, your broker (who is also your DP) will provide you with this number. It is automatically generated, so you don’t need to apply for it separately.
DP ID and client ID are two separate identifiers for your Demat account. The DP ID identifies your Depository Participant or broker, while the client ID is your unique account number with that DP. Together, they form your complete Demat account number, ensuring accurate identification of your account in the depository system.
The DP number in a Demat account, also known as the DP ID, is a unique identifier for your Depository Participant or broker.

They maintain your Demat account, facilitate buying and selling of securities, and provide various other services related to your investments in the stock market.
No, you can’t change your DP ID on your own. The DP ID is assigned to your Depository Participant or broker, not to you personally. If you want a different DP ID, you will need to open a new Demat account with a different DP.
