Every B# ID is a unique Universal Primary Key and references only one specific entity. B#IDs are universal. They can identify all the people, organisations, places or things across complex systems.
B# IDs are always registered, indexed and searchable free of charge. It costs nothing to create, assign or receive a B# ID. This provides a common language across all stakeholders whilst protecting your data at a lower cost.
Each B# ID is a primary key for the same entity across any data system. B# IDs enable free data exchange between users based on their own permissions.
