University ID Policy
University ID and Social Security Number
To help maintain the privacy of students’ Social Security Numbers, the Student Information System (SIS)
uses a random primary identifier for student records called the University ID (UID). The UID has replaced the Student
Identification Number (often the social security number) as the key to student records.
While the Social Security Number (SSN) is no longer the record key, it remains an important identifier for a
student. As permitted by Indiana Code 4-1-10, the last four digits of the SSN may be used to uniquely identify admissions applications, registrations, course
enrollment documents, transcripts, certification requests, and permanent academic records. The full nine-digit SSN is also necessary to
determine eligibility and as an identifier for federal grants and loans, and other federal financial aid programs.
In accordance with the Privacy Act of 1974 and Indiana Code 4-1-8, applicants for admission and enrolled students are advised that the requested disclosure of their Social Security numbers is voluntary. The applicant or student has the right to refuse disclosure of this number or request its removal from records without penalty. Note, however, that refusal to disclose the Social Security number would make a student ineligible for participation in federal Financial Aid programs.
