Correct, DTCC does not have access to the shareholder list, only the TA and the issuer. DTCC does have access to CEDE and all the clearing firms, but not physical holdings. An issuer can pay and request a Securities Positions Report from DTCC and request a current Shareholder List, and a Transfer Activity Report from the TA and see who owns what and where it went. It is a science and takes a few $ because you have to do it in a dynamic time frame, not static.
