Union Building Mailboxes

Registered student organizations are issued a mailbox on the third floor of the Union Building. The official address for student organizations mailing must be in this format:

(Name of the Student Organization)
University of Wisconsin-Milwaukee
P. O. Box 413 Milwaukee, WI 53201

Important University announcements, as well as incoming U.S. mail, are delivered to the Union Box. Packages which are too large for a mailbox are delivered to Student Involvement. Packages are to be picked up as soon as you are notified. If packages are not picked up promptly, they will be returned to sender.

As for the pickup, you will have to request mail from the front desk of Student Involvement. You will need to be a verified officer of an organization and present a valid Photo ID to be eligible to get your packages. 

Receiving Mail in Other Locations

Student organizations may have their group’s mailing address changed from their Union Box to a mailing location in another building on campus with special permission. In order to change the mailing address, organizations must complete a Mailbox Waiver Form. Student Involvement and Mail Services will not be held responsible for any delays or problems resulting from an organization changing its mailing address from a Union Box to another location. Although this service may provide convenience, student groups need to be aware of the following:

  •  Mail may take an additional 3-5 days to be delivered;
  •  Increased chance of mail being lost;
  •  Departments may not allow student organization mail to be delivered to their administrative offices.
