Short answer: yes, USPS delivers on Saturday, and it covers every mail class, from ordinary First-Class Mail to Priority Mail Express. Saturday runs on the same delivery schedule as a weekday, so mail can arrive any time up to the usual 8:00 p.m. cutoff. The only real difference is at the counter: most Post Offices keep shorter Saturday hours. The single day USPS does not deliver regular mail is Sunday, plus federal holidays.
Here is exactly what moves on a Saturday, when to expect it, whether it costs anything extra, how the two big private carriers compare, and what to do if the mail you were counting on does not show up.
Does USPS deliver on Saturday?
Yes. Saturday is a normal delivery day for USPS, and all mail classes are eligible:
- First-Class Mail (letters, cards, bills)
- USPS Ground Advantage (packages up to 70 lb, the service that replaced Retail Ground and First-Class Package)
- Priority Mail and Priority Mail Express
- Media Mail and Marketing Mail
The one thing that changes on Saturday is who delivers. USPS carriers work a rotating schedule, so on Saturdays your mail often comes from a substitute or a City Carrier Assistant rather than your regular carrier. They know the route a little less well, which is why Saturday mail can land at a different time than you are used to. Federal holidays are the only days regular Saturday-style delivery is suspended, and even then Priority Mail Express still runs.
Saturday vs Sunday at a glance
Most of the confusion about USPS weekend service comes from lumping the two days together. They are very different. This table lays out the split:
| Saturday | Sunday | |
|---|---|---|
| Regular mail (First-Class, etc.) | Delivered | Not delivered |
| Ground Advantage packages | Delivered | Not delivered |
| Priority Mail | Delivered | Seven-day areas only |
| Priority Mail Express | Delivered | Delivered (guaranteed) |
| Amazon packages | Delivered | Delivered (most metros) |
| Post Office counters | Limited hours | Closed |
In short, Saturday is a nearly full service day, while Sunday is reserved for premium and parcel volume. The complete Sunday rules are in does USPS deliver on Sunday.
What time does USPS deliver on Saturday?
Saturday follows the same window as any weekday. Most homes get their mail by early evening, with carriers officially able to deliver until 8:00 p.m. local time. Because a fill-in carrier is often covering the route, Saturday deliveries can run a bit later than your weekday norm, but the 8 p.m. cutoff still applies, and deliveries much past that are rare outside the December peak.
If it feels like your Saturday mail lands at a random time each week, that is largely the rotating-carrier effect: a substitute does not run the route in the exact same sequence your regular carrier does. For the full breakdown of the daily window and what drives it, see our guides on what time USPS delivers and how late USPS delivers.
Are Post Offices open on Saturday?
Many are, but only for limited hours, commonly a morning block such as 9:00 a.m. to 12:00 or 1:00 p.m. Hours vary a lot by location, and some larger or busier branches stay open into the afternoon while smaller ones close at noon or do not open at all. So if you need to visit the counter to buy postage or drop off a package, check your specific branch’s Saturday hours first rather than assuming.
This limited-counter reality is exactly what makes people wonder whether delivery happens at all on Saturday, but the two are separate. Carriers are out delivering their full routes even when the retail lobby closes early or stays dark, and self-service kiosks at many locations let you buy postage and drop prepaid packages any time. The lobby hours tell you nothing about whether your mail will be delivered that day; it will.
Does Saturday delivery cost extra?
No. There is no Saturday surcharge on standard services. First-Class Mail, Ground Advantage, Priority Mail, and Media Mail all deliver on Saturday at no additional cost. The trade-off is that none of those services guarantee a delivery time, so a Saturday arrival is expected but not promised.
Priority Mail Express is the exception that comes with a real guarantee: 1 to 2 days, delivered by 6:00 p.m., with your money back if it misses. Express is where a surcharge can apply, but only for Sunday and holiday delivery, not for ordinary Saturday delivery. So Saturday itself never triggers a weekend fee on any service. If you are weighing which service to use for a weekend deadline, run the two ZIP codes through our Delivery Time Estimator to see the realistic arrival window first, and our ZIP-to-ZIP delivery time guide explains how distance changes the estimate.
How to get a Saturday delivery
If you are the one sending, timing is everything, because Saturday counts as a delivery day but the transit clock still runs in business days.
For a Saturday arrival on Priority Mail (1 to 3 business days), drop it off early in the week. A package accepted Tuesday or Wednesday is well positioned to land Friday or Saturday; one accepted late Thursday probably slips to the following Monday. For a guaranteed weekend arrival, Priority Mail Express is the only sure route, and shipping it early on Friday gives it the best shot at Saturday. Amazon packages are the other reliable weekend arrival: order Thursday or Friday and a USPS carrier may well bring it Saturday. Remember that dropping something in a blue box after the day’s pickup pushes the acceptance scan, and therefore the whole timeline, to the next business day.
Do UPS and FedEx deliver on Saturday?
Yes, and Saturday is standard for both now rather than a special add-on the way it once was. UPS delivers to most residential addresses on Saturdays through UPS Ground, and FedEx delivers on Saturdays via FedEx Home Delivery across most of the country. That means if your USPS estimate lands on a Monday but you need something over the weekend, it is worth checking whether a private carrier can do better on your specific route. Our Shipping Cost Comparison tool puts USPS, UPS, and FedEx side by side so you can weigh weekend speed against cost for your package rather than guessing.
What about Sunday and holidays?
Sunday is the real dividing line. USPS does not deliver regular mail on Sundays. Only Priority Mail Express, Amazon packages, and some Priority Mail move that day. Federal holidays go further still: regular delivery is suspended and Post Offices close, with Priority Mail Express the only service that keeps running. When a holiday falls on a Friday or Monday, it stacks with the weekend to create a two- or three-day gap in regular mail, which is the most common reason a package seems to sit still over a long weekend. Before you ship around a holiday, it is worth checking the free Postal Holiday and Delivery Day Checker to confirm whether a given date is a delivery day for USPS, UPS, and FedEx.
My Saturday mail did not arrive — what now?
First, do not panic over a single day. Saturday mail runs later than usual fairly often because of the substitute carrier, and heavier volume, weather, or a route change can all push it past when you expected it. A late Saturday is usually just a late Saturday, and the item lands by early the following week.
It becomes worth investigating when the pattern is different. If your tracking flipped to Out for Delivery and the day ended with nothing in the box, the causes and fixes are in USPS out for delivery but not delivered. If the tracking simply went quiet for several days with no new scans, that is a separate issue covered in USPS tracking not updating. It is also worth double-checking that your address is complete, since a missing apartment or unit number is a common reason a delivery stalls. And if a Priority Mail Express package misses its guaranteed date, you are entitled to request a refund, which is a step no other service offers.
Frequently asked questions
Does USPS deliver packages on Saturday?
Yes. USPS delivers packages on Saturday across all services, including Ground Advantage, Priority Mail, and Priority Mail Express, at no extra charge over the standard rate.
What time does USPS deliver on Saturday?
Saturday follows the same window as a weekday, with most mail arriving by early evening and an 8:00 p.m. cutoff. It can run a little later than usual because a substitute carrier often covers Saturday routes.
Are Post Offices open on Saturday?
Many are, but only for limited hours, often a morning block such as 9:00 a.m. to noon. Hours vary widely by location, so check your specific branch before visiting. Self-service kiosks at many locations are available beyond counter hours.
Does USPS charge extra for Saturday delivery?
No. All standard services deliver on Saturday at no additional cost. A surcharge only applies to Priority Mail Express when you need Sunday or holiday delivery, not for ordinary Saturday delivery.
Why does my Saturday mail come later than on weekdays?
Because a substitute carrier or City Carrier Assistant usually covers Saturday routes rather than your regular carrier. They run the route in a slightly different order and pace, which shifts your delivery time.
Does USPS deliver on Sunday too?
Only Priority Mail Express, Amazon packages, and some Priority Mail are delivered on Sundays. Regular mail classes are not delivered on Sundays or federal holidays.
The bottom line
USPS delivers on Saturday for every mail class, on the same schedule as a weekday and at no extra cost, though your mail often comes from a fill-in carrier and can run a little later than usual. Post Office counters keep shorter Saturday hours, Sunday is reserved for Express and parcels, and holidays pause everything but Priority Mail Express. UPS and FedEx both run Saturday residential delivery too, so for a tight weekend deadline it is worth comparing carriers. And if a Saturday delivery misses, give it a day before worrying, and lean on your tracking to tell the difference between mail that is merely late and a package that is genuinely stuck.
I mailed a package that the Post Office sticker covered the address, and was sent back to me. I complained and asked for redelivery. They said they will Investigate. It has been 2 Months so far and PO has not answered my e mails.
When a label or sticker obscures the address and it bounces back, the clean fix is to re-cover or re-address the piece and remail it, and ask your local post office to note it for redelivery. If they are refusing a straightforward redelivery, escalate to the postmaster, since that is a processing error on their end, not yours.
