The majority of post offices are open Monday through Saturday and are closed on Sundays. Some post office sites will only have its lobby accessible on Saturdays so that customers may use their mailboxes, but they will not be able to access other United States Postal Service services and products.
If a location is open on Saturday, it will most likely be open for a limited time. Monday through Friday business hours are typically 8:30 a.m. to 4:30 p.m., however Saturday business hours are often between 11 a.m. and noon. Customers can still visit the post office’s outdoor drop boxes after hours and on holidays if they need to mail something.
