What’s the Person Number used for?

The Person Number is used to store a unique identifier for every person, excluding candidates, in the application.

The data model is designed such that you can associate multiple work relationships with each global person record. The Person Number isn’t intended to convey the type of relationship between the person and the enterprise.

A person can have multiple concurrent relationship types with the enterprise. For example, a person can be an employee, contingent worker, and a contact to another employee, all at the same time. Or a person can have multiple concurrent employee relationships with different legal employers.

Trying to use the Person Number to convey the relationship can cause confusion for a user, because the relationships may change over time or there may be various concurrent relationships.
