University ID Policy

University ID Number and Social Security Number

To maintain the privacy of students’ Social Security numbers, the Student Information System (SIS) generates a unique ten-digit identifier for each student record called the University ID (UID). The UID has replaced the Social Security number as the key to student records.

While the Social Security number (SSN) is no longer the student 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 admission applications, registrations, course enrollment documents, transcripts, certification requests, and permanent academic records. Access to the full nine-digit SSN is necessary to determine financial aid eligibility and the SSN is a required 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 the Social Security number 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 renders a student ineligible for participation in federal financial aid programs.
