PERSONAL MAIL

Mail services does not inspect each piece of mail to determine whether it is business-related. However, we do make this determination for parcels. Incoming personal shipments are handled as follows: Mail services will notify the addressee that a personal package has been received. The addressee must pick up their package within 48 hours after notification. Due to security concerns, the mail center cannot be responsible for lost or missing personal mail. If the package is not picked up within 48 hours, the package will be returned to sender. The addressee can pick up their shipment from the Mail Center at 660 W. Redwood St.. Howard Hall, Room 021.

Note: This policy only applies to materials sent through the U.S. Postal Service and delivered by UMB Mail Services.
