At the time of opening a demat account with Janata Bank the client has given a Standing Instruction to receive purchases automatically in his account. This 'Standing Instruction for Credit' is given in the account opening form itself. Thus due to this facility, a separate receipt instruction need not be submitted by the client for purchase of shares. To receive the credits directly your account, you must inform your broker your demat account number and the DP ID with Janata Bank, which is IN300280.
However the date of credit of these shares will depend on the broker and the DP has no role to play in the same.
