At UCSB we have many types of guests who are not students or employees but still need a netid to use campus services. The affiliate function of campus identity falls outside the scope of the Registrar and payroll and enables departments to create accounts manually. A Department Directory Editor (DDE) can create an affiliate using the Identity Manager. A search function is part of the process to pull in existing account data to ensure the affiliation is added properly if the person has a netid. Similar to faculty, staff & students, an identification number is generated called the annex locator. This is given to new people to activate their netid at the Identity Manager.
If you need an affiliate account please contact the UCSB department you are associated with.
