Mail services will allocate you a mail box number if you live on campus. Each residential area has a set of mailboxes for students. Mail is delivered once a day during the week. If you get a package, you will get a notification on your Binghamton University e-mail. You must have your Binghamton University student ID card to pick up a package at the post office/mail room in the University Union. The mail services web site shows you how to address mail to your on-campus box.
You will have a phone in your room. In order to make international or operator-assisted calls, you will need a pin number that you can request online from the telecommunications office.
