Common questions
What is Purdue's mailing address?
Purdue University, Office of Admissions, 2550 Northwestern Ave., Suite 1900, West Lafayette, IN 47906. All undergraduate admission materials, regardless of applicant location. Confirm the office address on Purdue'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 Purdue?
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 Purdue?
Official transcripts usually go to the admissions or registrar office in a sealed envelope from your prior school. Address it to Purdue at the office above (or the registrar, if given), and check whether Purdue also accepts secure electronic transcripts — many do.
Can I mail a letter to a student living at Purdue?
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 Purdue 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.
