Understand the meaning of DP ID, its structure, and its role in demat account identification, settlement, and securities records.
Last updated on: Jun 24, 2026
DP ID meaning refers to the unique identification code assigned to a Depository Participant, such as a broker, bank, or financial institution registered with a depository. It identifies the intermediary through which a demat account is maintained within the NSDL or CDSL depository system.
A Depository Participant Identification Number, commonly called DP ID, is a unique code assigned by NSDL or CDSL to a registered Depository Participant. It identifies the intermediary that provides demat account services and maintains securities records on behalf of account holders.
The dpid meaning is different from the meaning of a demat account number. A DP ID identifies the Depository Participant, while the complete demat account number identifies the individual account within the depository system.
A demat account number is structured using two main components:
DP ID: Identifies the Depository Participant, such as a broker, bank, or financial institution.
Client ID: Identifies the individual demat account holder within that Depository Participant.
Together, these two components form the Beneficiary Owner Identification Number, also called BO ID.
| Depository | DP ID Format | Client ID Format | Full BO ID Format |
|---|---|---|---|
NSDL |
IN + 6-digit DP ID |
8-digit Client ID |
IN30256712345678 |
CDSL |
First 8 digits of the 16-digit number |
Last 8 digits of the 16-digit number |
1204567812345678 |
The table below explains how DP ID and Client ID differ within a demat account structure:
| Parameter | DP ID | Client ID |
|---|---|---|
Purpose |
Identifies the Depository Participant |
Identifies the individual demat account holder |
Assigned To |
Broker, bank, or registered DP |
Individual account holder |
Format |
NSDL uses IN + 6 digits; CDSL uses 8 digits |
Usually 8 digits |
Uniqueness |
Common for all clients of the same DP |
Unique for each investor account |
Change Status |
May change if the demat account is transferred to another Depository Participant |
Changes when a new account is created |
The DP ID meaning is linked to intermediary identification within the depository framework. A DP ID helps depositories, clearing corporations, and Depository Participants identify the correct intermediary for securities-related records and transactions.
Intermediary Identification: DP ID identifies the Depository Participant responsible for maintaining the demat account.
Transaction Routing: DP ID helps route securities credit and debit instructions through the correct intermediary.
Corporate Action Allocation: DP ID is used in the processing of dividends, bonus shares, rights issues, and other corporate action entitlements to the correct depository participant and client account.
Regulatory Reporting: DP ID supports intermediary-level record maintenance and reporting requirements within the depository framework.

A DP ID is used in transaction routing, settlement processing, account identification, and depository-level record maintenance.
When a securities transaction is executed on an exchange, the clearing corporation determines the settlement obligation. The depository then uses the DP ID embedded within the BO ID to route the securities credit or debit instruction through the correct Depository Participant.
For example, when securities are credited after a purchase transaction, the DP ID helps identify the intermediary through which the securities must be credited to the relevant client account.
The DP ID supports the settlement process through the following flow:
Trade Execution: The exchange confirms the trade.
Settlement Obligation: The clearing corporation determines securities pay-in and pay-out obligations.
Depository Routing: The depository routes securities through the relevant DP ID.
Account Update: The client account is credited or debited after settlement.
The DP ID ensures correct intermediary mapping during the settlement process.
DP ID format differs between NSDL and CDSL, but its functional purpose remains the same. In both depositories, the DP ID identifies the Depository Participant that maintains the demat account.
DP ID in NSDL follows an alphanumeric format. It begins with “IN” followed by 6 digits.
Example: IN302567
In this format, “IN302567” identifies the Depository Participant registered with NSDL.
In CDSL, the DP ID is an 8-digit numeric code.
Example: 12045678
In a CDSL demat account, the first 8 digits of the 16-digit demat account number represent the DP ID, while the last 8 digits represent the Client ID.
The DP ID supports structured identification and routing within India’s securities market infrastructure.
DP ID helps route securities settlement instructions to the correct Depository Participant. It ensures that credits and debits are processed through the intermediary maintaining the relevant demat account.
DP ID is used to map corporate action entitlements such as dividends, bonus shares, rights issues, and stock splits to the correct intermediary and client account.
DP ID is also referenced in depository systems when securities are marked as collateral for margin purposes.

A DP ID identifies the Depository Participant, while a demat account number identifies the specific investor account maintained through that participant.
The demat account number is formed by combining the DP ID and Client ID. In NSDL, the account number includes an alphanumeric DP ID beginning with “IN” and an 8-digit Client ID. In CDSL, the 16-digit demat account number contains the DP ID as the first 8 digits and the Client ID as the last 8 digits.
The DP ID identifies the intermediary, while the complete demat account number identifies the account used for securities holding, settlement, and corporate action records.
A DP ID can be found in official demat account documents and depository-linked records. It may appear as part of the BO ID or demat account number, depending on the depository.
Common places where DP ID appears include:
Account Opening Documents: DP ID is mentioned in documents issued by the Depository Participant during account opening.
Holding Statements: Periodic demat holding statements may display the BO ID, which includes the DP ID.
Broker or DP Dashboard: Online account dashboards and mobile apps may show DP ID and Client ID details.
Consolidated Account Statement: CAS issued by NSDL or CDSL may include demat account identification details.
Demat Account Number: In CDSL accounts, the DP ID is the first 8 digits of the 16-digit demat account number. In NSDL accounts, it appears as an alphanumeric code beginning with “IN” followed by 6 digits.
The table below shows common use cases where DP ID appears:
| Use Case | Purpose |
|---|---|
IPO Applications |
Forms part of the BO ID used for demat account identification |
Securities Transfers |
Identifies the intermediary involved in the transfer |
Pledge Creation |
Supports collateral tagging within depository systems |
Corporate Actions |
Helps map entitlements to the correct intermediary and account |
Audit Records |
Supports reconciliation and account-level verification |

The Securities and Exchange Board of India regulates the framework under which Depository Participants operate. Depositories assign DP IDs within the approved regulatory structure.
SEBI oversight includes:
Registration Standards: Depository Participants must meet registration requirements.
Compliance Monitoring: DPs operate under SEBI and depository rules.
Audit Requirements: DP records and systems are subject to regulatory review.
Reporting Supervision: DPs maintain account and transaction records as required under applicable norms.
SEBI does not directly issue DP IDs, but it regulates the framework under which depositories and Depository Participants operate.
DP ID is often confused with other demat account identifiers. The table below explains common misconceptions:
| Misconception | Clarification |
|---|---|
DP ID is the full demat account number |
DP ID is only one part of the BO ID |
DP ID is unique for every investor |
DP ID is common for all clients of the same Depository Participant |
DP ID changes frequently |
DP ID changes only if the demat account is transferred to another DP |
DP ID is confidential |
DP ID appears in demat statements and account documentation |
The Depository Participant Identification Number forms part of the structured identification system used in India’s depository framework. A DP ID identifies the Depository Participant maintaining the demat account, while the Client ID identifies the individual account holder. Together, they form the BO ID used for settlement, holding records, corporate action processing, and regulatory tracking.
Reviewer
DP ID means Depository Participant Identification Number. It is the identification code assigned to a registered Depository Participant, such as a broker, bank, or financial institution, within the NSDL or CDSL depository system.
DP IDs do not follow the same format in NSDL and CDSL. NSDL uses an alphanumeric format beginning with “IN” followed by 6 digits, while CDSL uses an 8-digit numeric code.
In CDSL, the 16-digit number is the full demat account number or BO ID. The first 8 digits represent the DP ID, while the last 8 digits represent the Client ID.
DP ID and TPIN are not the same. A DP ID identifies the Depository Participant, while TPIN is an authorisation mechanism used for approving certain debit transactions from a demat account.
DP ID appears in account opening documents, holding statements, depository account views, broker or DP dashboards, and Consolidated Account Statements issued by NSDL or CDSL.
An investor may be linked to more than one DP ID if separate demat accounts are maintained with different Depository Participants. Each Depository Participant has its own assigned DP ID.
A DP ID appears in demat account numbers, account opening forms, holding statements, depository records, broker dashboards, and CAS records issued by NSDL or CDSL.
The full form of DP in the share market is Depository Participant. A Depository Participant is an intermediary registered with NSDL or CDSL to provide demat account services.
A DP ID identifies the Depository Participant responsible for maintaining a demat account. It supports transaction routing, settlement processing, corporate action mapping, and intermediary-level record maintenance.
A DP ID can be found in account opening documents, periodic holding statements, broker or DP dashboards, and Consolidated Account Statements. In CDSL accounts, the DP ID is the first 8 digits of the 16-digit demat account number. In NSDL accounts, it is the alphanumeric code beginning with “IN” followed by 6 digits.
A DP ID is not unique for every investor. It identifies the Depository Participant, not the individual account holder. All clients holding demat accounts with the same Depository Participant share the same DP ID.
DP ID identifies the Depository Participant, while Client ID identifies the individual demat account holder. BO ID, or Beneficiary Owner Identification Number, is the complete demat account number formed by combining the DP ID and Client ID.
A DP ID can change if a demat account is transferred from one Depository Participant to another. If an investor shifts holdings to an account maintained with another Depository Participant, the resulting demat account will reflect the DP ID and Client ID associated with that participant.
