Mail Services

United States Postal Services:

At the post office, you can mail letters and packages, arrange for Express mail, and buy postage stamps. When the Post Office is closed, customers can still go into the lobby to mail letters and buy stamps from a machine. Letters with a stamp attached may be mailed in the blue mailboxes that are located in numerous locations around town.

Mail is delivered six days a week, not on Sundays or national holidays. It will be delivered to your residence hall or apartment mailbox. You may also rent a post office box. If you move, it is very important to notify the Macomb Post Office and WIU.
