Mail collection from boxes is completed during customer service hours.  All resident students will have a SUMS (Student Mailbox) assigned to them, so that the university can effectively communicate important information to them. It is the responsibility of each resident student/SUMS mailbox customer to collect mail from their mailbox on a timely basis. 

Applications for new or returning resident students are sent out with residence hall contracts and may be returned to the Office of Residence Life with the contract or sent directly to the Student Life Office. New students enrolled for the Fall Term 1 will be notified by return mail during the summer of their box assignment and combination. Returning students' boxes will be returned to active status at the beginning of Fall Term 1 or on the date specified on their summer status form.
