Once an investor decides to trade in online equity shares and other investment options like mutual funds, bonds, government securities, and exchange-traded funds, he can approach a Depository Participant registered with either the NSDL or the CDSL. Once the documentation process is complete, the DP opens a Demat account for the investor, either with the NSDL or the CDSL.
The investor is provided with a Unique ID, your Demat account number. The total characters in every demat account number in India are 16; however, the format of the account number depends upon which central depository the account is opened with. In NSDL, the first two characters are alphabets determining the country the investor belong to (e.g., IN12345678987654 for India). For CDSL, every character is a numerical (e.g., 1234567898765432).
Every account number is a combination of the DP ID investor's client ID. The client ID is unique to every investor and identifies their specific portfolio. The first 8 digits are the DP ID, which is the unique identification number provided to the Depository Participant by the Central Depository. The next 8 digits are the investor's client ID. So for the NSDL, IN123456 is the DP ID, and 78987654 is the client ID.
If they wish to start buying the securities, the investors may have to provide a cheque. The DP, now as the investment broker, will purchase the electronic or dematerialized shares for you and maintain them in your Demat account. The investor can view them in the Statement of Holdings. If the investor chooses an online platform, the holdings can be viewed online. Generally, the shares are credited by the DP on a T 2 basis, i.e., Trading Day 2 days.
If the investor wishes to sell the shares, a delivery note with detailed information regarding the stock to be sold has to be given to the Depository Participant (DP). The DP will sell the respective shares, and the money will be credited to the investor. If the investor is using an online platform, the debit of shares and the credit of money are immediately visible in the account.
When the listed companies give out dividends or bonus, they get a list of their shareholders from the NSDL or the CDSL and thus credit the investor accounts.
