Where to Find BO ID?

There are three ways to find your Beneficial Owner Identification Number. You can follow any of the methods mentioned below to find it.

1. Check your Demat account statement: Your BO ID Number is usually mentioned on your Demat account statement issued by your Depository Participant (DP). The DP is responsible for maintaining your Demat account and providing you with regular statements that include your BO ID.

2. Check your Contract Note: If you have conducted any trades on the stock exchange, you would have received a contract note from your broker. Your BO ID is usually present on the contract note, along with other details such as trade date, settlement date, and brokerage charges.

3. Check your email or SMS: Your DP may send you regular updates and alerts related to your Demat account via email or SMS. Your BO ID may be present in such communications

However, in case you are unable to find it even by using these methods, then you can contact your Depository Participant (DP) and ask them to provide you with your BO ID. You can either call them or visit their office in person with your Demat account details and identity proof to obtain the information.

What is DP ID?

The agent of the depository is commonly known as a depository participant or simply a “DP.” A Depository Participant (DP) is like a middleman between investors and the stock exchanges. Usually, it’s financial institutions, brokerage firms, and banks that act as DPs. They follow guidelines from the Depositories Act of 1996, which outlines how depositories and DPs should work together.

How to Find DP ID & Demat Account Number? 

Now that we have understood BO ID meaning and how to get bo id in cdsl, here is your turn to find your DP ID. 

Your Demat account number is a unique 16-digit alphanumeric code given to you by your Depository Participant (DP). Once you successfully open a Demat account online, you’ll get a welcome letter from the depository (either CDSL or NSDL). This letter will have all your account details, including your Demat account number. If it’s with CDSL, your Demat account number is also called the Beneficiary Owner ID (BO ID). 

Remember, if your Depository Participant (DP) is National Securities Depository Limited (NSDL), your account number (ID) will begin with IN, followed by 14 digits. In the case of CDSL as your DP, the ID will consist of 16 digits.

How is a Demat A/C different from a Depository Participant (DP) Identification (ID)? 

Your DP ID and Demat Account number are not the same, and they don’t represent the person who owns the Demat account. A bank or brokerage company is an example of a depository participant, and they get assigned a DP ID by NSDL or CDSL. 

Therefore, your DP ID and customer ID are combined to create a Demat A/c no. Typically, the first eight characters of your Demat Account number are your DP ID, and the last eight characters are your customer ID.

How is a BO ID Different from a DP ID and a Client ID?

In simple words, your BO ID is like your demat account number, made up of your DP ID and your client ID. The DP ID is the first eight digits that tell if your account is with CDSL or NSDL. Both depositories use these numbers to identify participants. Your client ID is the unique last eight digits of your account number. The BO ID is the full 16-character account number. Thus, understanding this helps you handle your securities easily.
