A Saturday at USPS looks like any weekday, but Sunday is another story. So does USPS deliver on weekends? Saturday is a regular delivery day for almost all mail and packages, while Sunday is limited to certain parcels such as Priority Mail Express and Amazon packages.
The two weekend days work nothing alike. A letter that arrives like clockwork on Saturday will not move at all on Sunday.

Does USPS deliver on Saturday?
Yes, everywhere USPS delivers. Carriers run their full routes on Saturday, just like a weekday. There is no extra charge.
First-Class Mail, magazines, Ground Advantage packages and Priority Mail all move. A bill mailed on Thursday can land in your box on Saturday.
Six day delivery is a long standing USPS commitment. Saturday is not a reduced service day for delivery, even though many post office counters keep shorter hours.
What time USPS delivers on Saturday
Saturday mail usually arrives in the same window as weekdays. Most routes finish by late afternoon.
Carriers can deliver as late as 8 p.m., especially on busy routes. Our guide to USPS delivery times explains what affects your route.
Post offices on Saturday
Delivery and counter service are separate questions. Many post offices open on Saturday with shorter hours, and some close by early afternoon.
Check before you drive over. Our guide to post office hours on Saturday covers what to expect.
Does USPS deliver on Sunday?
Only certain packages. Sunday is a parcel day, not a mail day.
Letters, bills, cards and magazines never move on Sunday. They wait for Monday, or Tuesday after a Monday holiday.
What USPS delivers on Sunday
- Priority Mail Express, which is delivered every day of the year.
- Amazon packages, in most metro and suburban areas.
- Some other parcels on routes that already run on Sunday, mostly in busy areas and during peak season.
USPS Ground Advantage is not scheduled for Sunday delivery. Plan for a Ground Advantage package to arrive Monday through Saturday.
Priority Mail Express on Sunday
Priority Mail Express is the only USPS service you can count on for Sunday. The retail price adds a $12.50 Sunday and holiday delivery fee.
Confirm Sunday service for the destination ZIP code before you pay. The counter clerk or the online label tool will show the delivery commitment.
Why USPS treats the two days so differently
USPS funds itself through postage, not tax dollars. It runs routes where volume pays for them.
Saturday has always carried enough mail to justify a full delivery day. Sunday never did, until online shopping changed the math for parcels.
The modern Sunday route started with Amazon in 2013, beginning in New York and Los Angeles. Sunday service is still built around that parcel volume, plus Priority Mail Express.
Does your address get Sunday delivery?
There is no public map of Sunday routes. Dense metro and suburban ZIP codes usually have them, while rural routes often do not.
Your tracking page is the best signal. Once a package is scanned, USPS shows an expected delivery date, and a Sunday date means your route runs that day.
A history of Sunday Amazon deliveries is another clue. If those arrive, your address is on a Sunday route.
Post offices on Sunday
Nearly every post office is closed on Sunday. You cannot buy postage at a counter or pick up a held package.
Blue collection boxes, and kiosks in lobbies that stay open, still accept mail. Anything dropped on Sunday is not processed until Monday. Our guide to USPS hours on Sunday covers the exceptions.
Does USPS deliver on weekends to PO Boxes?
On Saturday, yes. Mail is placed in PO Boxes on Saturday, though lobby access hours depend on the post office.
On Sunday, no. PO Box mail is not distributed, and most lobbies are locked.
Informed Delivery on weekends
Informed Delivery emails go out Monday through Saturday. You get a Saturday preview of the letters headed to your box that day.
No email arrives on Sunday, because no regular mail moves. Package notices can still update when a Sunday parcel is delivered.
Weekends next to federal holidays
A federal holiday suspends regular delivery. When it falls on a Monday, a letter mailed Friday may not arrive until Tuesday.
Only Priority Mail Express keeps running through a holiday. Run any date through our holiday and delivery day checker before you plan around it.
Planning a shipment around a weekend deadline
If you are asking does USPS deliver on weekends because of a deadline, start with the service.
Need something to land by Saturday? Priority Mail usually takes one to three business days, so ship early in the week. Our delivery time estimator shows the window for your route.
Need it by Sunday? Use Priority Mail Express and confirm the commitment for the destination. Nothing else from USPS carries a Sunday guarantee.
Private carriers are worth a look too. FedEx Home Delivery reaches much of the country on Sunday, as our guide to FedEx weekend delivery explains.
The bottom line
Does USPS deliver on weekends? Saturday works like any weekday for nearly every mail class, at no extra cost.
Sunday is reserved for Priority Mail Express, Amazon packages and some other parcels on Sunday routes. Regular mail always waits for Monday.
