Customer Label Distribution System (CLDS)

CLDS is a web-based application that provides mailers with the capability to create, edit, and locally print Intelligent Mail tray labels. Tray labels are no longer printed by the Topeka National Print Center (NPC). CLDS is scheduled to be replaced in January 2023 with a user-friendly updated tray label application.
