The abbreviation DP in the investment market denotes a Depository Participant. There are two major depositories in India - the National Securities Depository Limited (NSDL) and the Central Depository Services Limited or the CDSL. Both depositories have their own network of depository participants that serve as a link between them and the securities issuing companies. Essentially, a DP is simply a financial institution such as a brokerage house (like Mirae Asset) or Bank registered with the SEBI. Anyone interested in investing in market securities, including IPOs, must open a Demat and trading account with a DP and specify the DP ID on the Initial Public Offering application form.
