Common questions
What is CSU's mailing address?
Colorado State University, Office of Admissions, 1062 Campus Delivery, Fort Collins, CO 80523-1062. Undergraduate admission documents and official transcripts mailed to the admissions office. Confirm the office address on CSU'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 CSU?

How do I send an official transcript to CSU?

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