Common questions
What is USC's mailing address?
University of Southern California, Office of Admission — Undergraduate, University Park Campus, Los Angeles, CA 90089-0911. Undergraduate admissions and application documents (a campus ZIP, so no street line is needed). Confirm the office address on USC's official contact page before anything deadline-driven — admissions and registrar offices sometimes use a different PO box.
Where do I mail admissions or application documents to USC?
Send them to the admissions office. Use the admissions address listed above. Include your applicant ID or Common App / application number, and mail well ahead of the deadline — the postmark or receipt date is what counts.
How do I send an official transcript to USC?
Official transcripts usually go to the admissions or registrar office in a sealed envelope from your prior school. Address it to USC at the office above (or the registrar, if given), and check whether USC also accepts secure electronic transcripts — many do.
Can I mail a letter to a student living at USC?
Yes, but a student in residence has their own campus mailbox address (residence hall + room or mailbox number), which is not the same as the office address above. Ask the student for their exact residence mailing address; the school's housing or mail-services page also explains its format.
Will someone read my letter or write back?
University offices route incoming mail to the right team, so a correctly addressed letter does get handled — but a personal reply isn't guaranteed. Including your return address, an ID or reference number, and a clear request gives you the best chance of a response.
How do I mail USC a letter without a printer?
Write or upload your letter to PostPal with the address prefilled. We print it, add your return address, and mail it for you — no printer, stamps, or post office trip needed.
