Does USPS Deliver on Saturday? Yes, Delivery Rules
Saturday is a normal USPS delivery day, but that does not mean every Post Office retail counter is open or that every mailpiece is guaranteed to arrive Saturday.
Quick answer
Yes, USPS delivers on Saturday. If you absolutely need something to arrive that day, Priority Mail Express is the only option backed by a money-back guarantee. Other mail types do not carry a money-back delivery guarantee. From what I have seen using rural Post Offices, Saturday delivery can be less predictable. I have had mail that was expected Saturday arrive Monday instead, although that is not standard USPS practice.
Are Post Offices open on Saturday?
Running The Letter Pilot means I spend a lot of time dealing with USPS and dropping off customer mail. At the locations my team and I have used, including small-town branches such as Bellvue, Colorado, Saturday hours vary widely. Many larger offices close around 1, 2, or 3 p.m. Smaller branches may close at noon or not open on Saturday at all.
Hours vary by location, so check the USPS locator before making the trip.

Saturday Mail Pickup and Collection
Yes, USPS collects mail on Saturdays. If your carrier is delivering to your address, they can also take eligible outgoing mail when your mailbox flag is raised. Many Post Office lobbies and pickup locations are open on Saturday with the limited hours noted above. For blue collection boxes, the pickup schedule is posted on the front, so check the label for that box's Saturday collection time before dropping in your mail.
