does the usps deliver mail on saturday

does the usps deliver mail on saturday is a common question for customers who need to know about the post office’s weekend delivery services. USPS does deliver mail on Saturdays, and it includes both First-Class Mail and Priority Mail. Saturday delivery helps keep shipments on schedule, especially for time-sensitive items. However, USPS does not deliver regular mail on Sundays, unless it’s a special service like Priority Mail Express, which can be delivered on Sundays at an additional cost.
