The Undergraduate Package Center is located in the lower level of Wien Hall. Mailboxes are located on the 3rd and 4th floors of Lerner Hall.


Packages should be addressed to a student's mailbox. The Undergraduate Package Center holds packages for up to 14 days and sends regular email notifications to students during this time.
