The United State Postal Service has provided blue letter boxes on campus for personal prestamped mail and small parcels. The mailboxes can be found in two locations on campus:
- North Perimeter Rd., in front of the Administration building
- Corner of North Perimeter Rd. & University Dr., in front of the Library
United States Postal Service letter boxes are for personal prestamped envelopes and small parcels only. Pre-stamped parcels that are unable to fit in the letter boxes should be dropped off at Distribution Services or Canyon Post for pickup by the United States Postal Service.
Prestamped official Cal Poly mail should be placed in the red campus mail bags for processing by Distribution Services.
