The first address entered for a participant is the primary address and it is displayed throughout the application. A participant can only have one primary address of each address type: postal, web and email. It ensures that multiple correspondences, payments and bills that can exist in a case are automatically directed to a single address, unless otherwise specified. Primary address functionality does not apply to the organization or it's locations.
Where the organization is using participant evidence to maintain person and prospect information, see the Cúram Participant Guide for further details on how the person or prospect persons address is derived.
