Access Your Student ID

In the past we used student Social Security numbers as student identification numbers. Now, in order to protect your Social Security number (SSN), the Student Information System (SIS) uses a random primary identifier for your records called your Student ID.

  • Find your Student ID in the Student Center.
    1. Go to the Student Center. (via One.IU)
    2. Click the Start button.
    3. Login to CAS using your network Username and Password (if prompted).
    4. Locate the Personal Information section, and click Demographic Data.
    5. Your 10-digit (Student) ID is located under the Demographic Information header.

While the SSN is no longer your identification number, it remains an important identifier.

As permitted by Indiana Code 4-1-10, the last four digits of your SSN may be used to uniquely identify admissions applications, registrations, course enrollment documents, transcripts, certification requests, and permanent academic records. Your full nine-digit SSN is also necessary to determine eligibility and serves as an identifier for federal grants and loans, and other federal financial aid programs.

If you are an applicant for admission or a currently enrolled student, the disclosure of your SSN at our request is voluntary. As an applicant or a current student, you have the right to refuse disclosure of this number or request its removal from records without penalty. This is in accordance with the Privacy Act of 1974 and Indiana Code 4-1-8.

This is important: refusal to disclose your SSN will make you ineligible for participation in federal financial aid programs.
