Upcoming Change: U4 firmAssociations.officeLocations Address Behavior K29547 Mon, 10/05/2026 - 14:29 An upcoming change is being made to how U4 location addresses are handled. Please review the behavior below: Registered Locations (Main Office / Locations with Branch CRD): Any address provided via U4 submissions under firmAssociations.officeLocations will be ignored — the existing registered address will be retained. Note that previously, if bdMainOfficeIndicator was set to true for a location, the branch was receiving the main office address.
