Common questions
What is LSU's mailing address?

Confirm the office address on LSU'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 LSU?

How do I send an official transcript to LSU?

Can I mail a letter to a student living at LSU?
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.
