Keep this in mind when shipping and mailing items. USPS does deliver on Saturday, although has short business hours and is closed on Sundays, and are closed on federal holidays. Check your local post office hours before visiting your local location. Local office hours vary from 8 AM to 6 PM Monday through Friday, but some offices close earlier. Everyday except Sunday is a USPS business day. If you need to mail a letter or package or check your PO box, check the USPS’s varying hours of operation.

However, a lot of factors could delay your mail delivery such as weather and high demands around holidays. All deliveries should be made by 5 PM local time Monday through Saturday. Your local delivery time depends on where you are in the delivery route. If you need a more robust way of managing your mail on weekends ( and weekdays), USPS’s PO box and Informed Delivery may fall short for what you need. If you have USPS Informed Delivery, you’ll receive a preview of what’s on its way-but that’s it. Do you have a package estimated to be delivered over the weekend? If your delivery is going to your PO box, keep in mind USPS has limited hours on Saturdays and are closed on Sundays.
