What is a Client ID in a Demat Account?

A Client ID is a unique 8-digit number assigned by a Depository Participant (DP) (such as SBI securities, paytm money and indimoney). It forms part of your 16-digit Demat Account Number, which is structured as follows:

• First 8 digits → DP ID (Identifies your broker or depository participant)
• Last 8 digits → Client ID (Uniquely identifies your demat account)

Example:
If your Demat Account Number is 1243450067891235, then:

• 12434500 is the DP ID
• 67891235 is the Client ID

Purpose of Client ID:

• Helps depositories like NSDL/CDSL track your securities.
• Used to hold shares in electronic form.
• Needed for transferring stocks between accounts.
• Contact with company as shareholder through phone or email

What is a Client Code in a Trading Account?

A Client Code is assigned by your stockbroker to track your trading activities. Unlike the Client ID, which is used for holding shares, the Client Code is used for buying and selling stocks on stock exchanges like NSE and BSE.

• The Client Code is unique to each broker, meaning it can differ if you have accounts with multiple brokers.
• It is often alphanumeric (e.g., ABC12345).

Purpose of Client Code:

• Identifies you in the broker’s trading system.
• Helps brokers track transactions, orders, and trades.
• Used for generating contract notes and tax reports.
• use as demat login id on desktop
• talk with rm or customer care of broker.
