Demat account number and DP ID are a unique set of details that a customer gets when they open their Demat and Trading A/c. A Demat account number is essential for everyone participating in the stock market. It allows traders and investors to continue trading digitally. Once the Demat account is opened online with our Trading app, a welcome letter is sent by the depository (CDSL/NSDL) to the user that contains all the account information including the Demat account number.

What is a Demat Account Number?

A Demat Account number is a 16-digit account number that is unique to every Demat account holder. This is provided once a user creates their Demat and Trading account with any stockbroker. The Demat account number varies for the two depositories CDSL and NSDL. For CDSL, the Demat account number is also known as Beneficiary ID or BO ID. This is completely a 16-digit numeric ID. Whereas, for NSDL, it starts with “IN” followed by a 14-digit numeric code.

What is a DP ID?

DP ID is different from a Demat account number.Like a Demat account number is unique to every individual participating in the stock market, a DP ID is a unique number allocated to the broking firm or financial institution that helps you with your Demat account. This is provided by CDSL and NSDL to the DP (Depository Participant).

Importance of Demat Account Number

The Demat account number is very important as it’s the number against which your orders are mapped when you trade in the share market. The Demat account number is unique to your investments and helps the stockbrokers to map the transactions that are done in your Demat account.

Moreover, if an investor has multiple Demat accounts, identifying the investments done in different Demat accounts will be tough. Therefore, Demat account number is helpful in segregating the investments of various Demat accounts and organizing the trades & the portfolio in a systematic way.

How to know my Demat Account Number?

As discussed earlier, a Demat account number is provided by the depositories, NSDL and CDSL. When you create your Demat & Trading A/c with a stockbroking firm, you receive these details via email from the depositories. You can find this on the web and app platform of your stockbroker as well.

For Bajaj Broking customers, they can find this in their profile section of the app and the web platform. The Demat Account number differs for both the depositories. For CDSL, the Demat account number is also known as Beneficiary ID or BO ID. This is completely a 16-digit numeric ID. Whereas, for NSDL, it starts with “IN” followed by a 14-digit numeric code.

What is the Depository Participant?

A Depository Participant is a stockbroker, bank, or financial institution that helps act as a medium between a trader or investor and the stock exchange. In simple terms, if you have a Demat & Trading A/c with Bajaj Broking then, Bajaj Broking is the Depository participant in this case.

How DP ID differs from the Demat Account Number?

The Demat account number is the complete 16-digit unique code, whereas DP ID is the first 8 digits of the Demat Account number. The remaining 8 digits is your customer ID. Considering the Demat account number may differ for both CDSL and NSDL, let us understand them with a simple example.

Sample account numbers shown below to help you get familiar with the format:


Demat account number – 1020304050607080


Demat account number – IN11223344556677

What is the difference Between CDSL and NSDL?

Both Central Depositories Services India Ltd. (CDSL), and National Securities Depository Ltd, (NSDL) are government registered share depositories in India. Shares are held in an electronic format in the depositories. It’s crucial to understand the difference between the two to find out the 16-digit Demat account number because it will be based on the stockbroker’s affiliation (either CDSL or NSDL). Therefore, to avoid mistakes at the time of quoting your Demat account number, let’s take a look at the fundamental difference between the two in a tabular form.
