What is my DP name, DP ID, BO ID, and demat ID?

Your DP name identifies the organisation maintaining your Demat account, while the DP ID, BO ID, and Demat ID identify the participant and your individual account.

• The DP name is the bank, broker, or financial institution that maintains your Demat account.
• The DP ID is the identification code assigned to your Depository Participant by CDSL or NSDL.
• For a CDSL account, the BO ID is the complete 16-digit Demat account number.
• An NSDL account number combines an 8-character DP ID with an 8-digit Client ID.
• Demat ID is a commonly used term for the complete Demat account number.

• You can find these details in your account statement, welcome email, profile section, or Client Master Report.

  
  
  

A Demat account, short for a dematerialised account, holds shares and other securities electronically. It replaces physical ownership certificates with digital account records.

You may use a Demat account to hold instruments such as:

• Shares
• Bonds
• Mutual fund units
• Government securities
• Exchange-traded funds
• Other eligible financial instruments

When you purchase securities, they are credited to your Demat account. When you sell or transfer them, the relevant securities are debited from the account.

This electronic system reduces physical paperwork and makes it easier to maintain records of your holdings. However, you must understand the identifiers connected with your account to complete transfers, applications, and account-related requests correctly.

A Depository Participant, or DP, is an organisation authorised to provide depository services to investors. It acts as an intermediary between you and a depository such as CDSL or NSDL.

Banks, financial institutions, and registered stockbrokers may operate as Depository Participants. The depository holds securities within its system, while the DP opens and maintains your individual Demat account.

Your DP name is the registered name of the organisation through which your Demat account is maintained. You can usually find the DP name in:

• Your Client Master Report
• Demat account statements
• Account-opening correspondence
• Transaction statements
• Your account profile

The DP helps process activities such as the credit, debit, transfer, dematerialisation, and rematerialisation of securities.

A Depository Participant Identification Number, commonly called a DP ID, is the code assigned to a Depository Participant by CDSL or NSDL. The DP ID identifies the organisation maintaining your account. It does not identify your individual account on its own.

For example, if a CDSL Demat account number is 1234567812345678, the structure would be:

• DP ID: 12345678
• Client ID: 12345678

• Complete BO ID: 1234567812345678

  
  

For an NSDL account, the DP ID is an 8-character code, while the Client ID contains 8 digits. The combination forms the unique NSDL account number.

You can check your DP ID in your Client Master Report, Demat statement, or account-opening documents.

BO ID stands for Beneficial Owner Identification Number. You become the beneficial owner of the securities held in your Demat account.

For a CDSL account, the BO ID is the complete 16-digit Demat account number. It contains:

The BO ID is not a separate number added to the DP ID. Instead, the DP ID forms the first part of the 16-digit BO ID. CDSL defines the BO ID as the Demat account number consisting of an 8-digit DP ID and an 8-digit Client ID.

You may find your BO ID in:

• Your CDSL account statement
• Your Client Master Report
• Transaction emails
• Your account profile

• Documents issued when the account was opened

  
  

The BO ID helps the depository and DP identify the correct account when processing securities transactions.

A Demat ID generally refers to your complete Demat account number. Its structure depends on the depository with which your account is maintained.

For CDSL accounts, the terms BO ID, Demat ID, and Demat account number are often used for the same 16-digit number. For NSDL accounts, the complete Demat ID contains the DP ID and Client ID. The DP ID generally begins with “IN”.

Your Demat ID may be required when:

• Applying for an IPO
• Transferring securities
• Linking eligible investment accounts
• Completing depository-related authorisations

• Raising an account-related service request

  
  

Enter the full account number carefully. Using only the DP ID will not identify your individual Demat account.

Understanding your DP name, DP ID, BO ID, and Demat ID helps you manage your Demat account correctly. These details identify your Depository Participant and individual account within the CDSL or NSDL system. You may need them for IPO applications, securities transfers, account authorisations, and service requests. Always verify the complete account number through your Client Master Report, Demat statement, welcome email, or account profile before submitting any transaction.
