  • The DP ID full form refers to Depository Participant Identification. It is an eight-digit unique code that is assigned to a Depository Participant by an authorised depository such as NSDL or CDSL. It is the first eight digits of the 16-digit Demat account number, with the rest constituting the customer ID. The DP ID acts as an important element in securities trading. It helps ensure accurate tracking and secure transfer of securities between Demat accounts, thereby maintaining transparency and authenticity in all trading activities. This article explains what DP ID in Demat account is.

    Example of DP ID in Demat Account 

    The following example helps get a clear understanding of DP ID in a Demat account and a way to recognise it from a Demat account number 

    As per fundamentals, DP ID + Beneficiary ID = Demat ID 

    • For instance, take the CDSL Demat account number 123567888664422 as an illustration. Here, the first eight numbers stand in for the DP ID (12345678), while the last eight numbers (88664422) stand in for the customer ID or beneficiary ID. 
    • The NSDL Demat account number will show up as IN12345678664422. Your nation is identified by its first two letters, which are India. The country code and the next six numbers make up the DP ID. Thus, IN123456 is the DP ID, and 78664422 is the beneficiary or customer ID.

    Understanding DP ID in NSDL and CDSL 

    The two central depositories regulated by the Securities and Exchange Board of India (SEBI) include the National Securities Depository Limited (NSDL) and the Central Depository Services Limited (CDSL). When you open a Demat account, a welcome letter from either NSDL or CDSL will be sent with a 16-digit Demat account number that includes the DP ID. 

    In the case of CDSL, the Demat account number is a 16-digit numeric combination, and this number is also termed the Beneficiary Owner ID or BO ID. Whereas, NSDL Demat account numbers start with the "IN" prefix followed by 14 digits. The first eight digits in both formats denote the DP ID allotted by the respective depository to the depository participant.
