2020 Saturday Schedule for SMC Package Pickup

Departmental Delivery Address Format

Please use the new addressing format for non-USPS carriers when placing any orders for campus delivery by a carrier other than USPS. Not using the new format for departmental deliveries (especially those ordered through an Amazon Business account) increases the likelihood that the parcels will be delivered to the wrong location, lost, or returned to the sender. If you have any questions regarding departmental deliveries, please contact us at

Abandoned Amazon parcels should be reported to CMU Postal Services at

Also note that the addressing format for SMC mailboxes remains unchanged for all carriers.

Personal Packages for Faculty and Staff

Personal packages destined for faculty or staff should not be addressed to a campus location. Having personal packages sent to campus locations, especially during the holidays, can overload the campus mail system. This can lead to significant delays for items deemed time-critical and essential to the operation of the university. Convenient and secure SMC mailboxes are available to rent in order to receive personal packages on campus.

Medical and Time-Critical Items

Please be sure to use your correct address when sending medical and time-critical items to your campus location. Any mail or parcels bearing an address that does not contain enough information for delivery will be returned to the sender. Faculty and staff deliveries must include the name, department, building abbreviation, and room number. Mail or parcels destined for an SMC must include the name and SMC within the address. Please verify that the sender has the correct information before placing an order so that the mail or parcel is able to be delivered correctly and in a timely manner.
