A User ID is automatically set for a new user in the following scenarios:
- A user is created via the Add User page. See User Record - Add.
- A user self-registers in the system where the self-registration group is configured so that User IDs are generated by the system.
- A user is created via the Data Load Wizard using the User Load. See Load User Data (Cornerstone HR) - Overview.
Each User ID must be unique. Because of this, once a User ID value is generated, that value is permanently reserved and cannot be reused.
User ID Prefix
The prefix that appears at the beginning of all User ID values is determined by a backend setting, which is set during implementation.
User ID Length
The number of characters contained in the User ID is determined by a backend setting, which is set during implementation. The minimum length is six characters, and the maximum length is eight characters.
