Mandated by members of Chinese Securities Association, TDCC has established an account query system with detail data provided by securities brokers. Investors will need to apply for a password individually with designated brokers. (Please note it is not necessary to apply for any password if only the bond-passbook checking function is needed.) The query system can be used to check the depository book-entry account information.

In addition, TDCC launched an offshore fund query system for investors who purchase offshore funds through the designated general agents or sales organizations. The query system helps investors to update information and to control their investment risks. An initial password can be applied with the sales organization and be changed by the investor after logging in the query system.
