Departments, or individuals, shipping any combination of campus mail, international mail, and unsealed mail should separate the categories by binding them with an elastic band. All outgoing mail requires a return address with a student box number or a departmental mail code. To prepare international mail, use the USPS Customs Form Indicator to determine whether it is necessary to complete a customs form.
A University-wide mail code system is in place for sending and receiving mail which also connects with department accounts. The mail code is the 4-digit extension of the department, typically as listed in the phone directory. A mail code is not a person's personal extension number.
A department's mail code should be added to the end of the University zip code. Please call Mail Services to find out a department's mail code.
To find a zip code, just click on the USPS icon below and follow the instructions.
