Post Office Holiday hours : 10am-4pm
Saturday hours are 11:00 a.m. to 3:00 p.m.

There is NO retail service available on Saturday only package pick up.

It will act like an official USPS Post Office. It will sell stamps. It will be able to process overnight packages and process certified and return receipt mail.

 You may pay by cash, credit card or debit card for these and all USPS products and services.

Who will run the new Campus Post Office?

The Campus Post Office will be operated by Saint Mary’s staff and student workers.

Will departments still have PO boxes?

There will be no changes in PO boxes. Campus mail boxes will be intergrated with the existing PO boxes in the Campus Post Office in order to bring everything into one location.

Will anyone be able to have a PO box now?

Due to space limitations, the existing rule that only campus community members living on campus will be allowed to rent boxes will remain in effect.  An audit of boxes will be done to determine if extra boxes will be made available to other members of the campus community.


Who should I contact if I need further information?
