Abandonment of Parcels by Amazon

Please be advised that due to the continuing abandonment of parcels around campus by Amazon drivers, we are strongly encouraging faculty and staff to use the new addressing format for non-USPS carriers. Not using the new format for departmental deliveries (especially those being delivered directly by Amazon) increases the likelihood that the parcels will be abandoned in an unsecured area on campus.

Please note that any deliveries addressed to a department through any carrier other than USPS will be delivered directly by that carrier. Postal Services only delivers campus (interdepartmental) mail and items received from USPS. Any issues or concerns regarding items being delivered by a carrier other than USPS (Amazon, FedEx, UPS, DHL, etc.) should be made known directly to that carrier. Abandoned Amazon parcels should be reported to Amazon at 206-678-3213.

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

Addressing Non-USPS Parcels to CMU Faculty and Staff

Please note that the format for addressing non-USPS parcels has been updated. Full details can be found in our Incoming Mail for Faculty and Staff section.

2019 Saturday Schedule for SMC Package Pickup

We have released a full list of our 2019 Saturday hours for the SMC Package Pickup Window. If you have any questions or concerns, please contact us.

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.
