The Underwriting eligibility request platform, UW Source (which provides access to the New Issue Information Dissemination System, “NIIDS”) can be accessed by logging in through the “DTCC Web App Login” located in the upper right corner of any page on DTCC.com or through the “SMART” Network.

Registration for the UW SOURCE application is controlled through the assignment of Super Access Coordinators (“Super ACs”). The Super AC is given access to DTC’s Customer Registration System (“CRS”) which allows the Super AC to register other users at their firm for UW SOURCE.

Firms that do not have a Super AC must execute a Super Access Coordinator Authorization Form for DTCC Systems and Applications for Underwriting (the “Super AC form”), designating an individual or individuals at their firm as Super ACs. Once registered and granted the necessary entitlements by DTC, the Super AC will be able to register and modify the registrations of other users at their firm for the UW SOURCE application.

Please note that the registration process takes up to 72 hours to complete once all required documentation is received by DTCC.
