USPS delivers millions of packages across the United States every day, but many people are still unsure whether mail arrives on Sundays. So, does USPS deliver on Sunday for regular mail service?
1. Does USPS Deliver on Sunday?
Does USPS deliver on Sunday for all mail and packages? Not exactly. Sunday delivery is primarily reserved for Priority Mail Express, which includes a delivery guarantee every day of the year, and selected package services based on operational needs.
In recent years, USPS has expanded Sunday package delivery to handle the rapid growth of e-commerce. During busy periods, especially the holiday season, the Postal Service delivers additional packages in major cities and other high-volume areas to reduce backlogs and keep its network running efficiently.
USPS has also long provided Sunday delivery for certain Amazon orders through its partnership with Amazon. Depending on package volume, destination, and local postal operations, other packages may also be delivered on Sundays in eligible ZIP codes.
Does USPS deliver mail on Sunday? However, services such as First-Class Mail, Marketing Mail, and most standard letters are delivered only Monday through Saturday.
Generally, regular First-Class Mail, USPS Ground Advantage, Marketing Mail, and most standard letter mail are not delivered on Sundays. If your package is scheduled for Sunday delivery, you’ll usually see that information reflected in your USPS tracking updates.
2. Which Packages Are Eligible for USPS Sunday Delivery?
In short, the packages most likely to be delivered on Sunday include:
- The most common package type delivered on Sundays is Priority Mail Express. This premium service includes seven-day delivery.
- In addition to Priority Mail Express, Priority Mail packages may also be delivered on Sundays, particularly in areas with high shipping demand.
- USPS may also deliver First-Class Package Service shipments (now generally handled under USPS Ground Advantage for many retail shipments) when package volumes justify additional Sunday routes.
- Customers living in ZIP codes that participate in Amazon Sunday Delivery will continue receiving eligible Amazon orders on Sundays. These deliveries are part of USPS’s ongoing partnership with Amazon and are available only in participating service areas.
For any shipment, checking the USPS tracking page is the easiest way to see whether Sunday delivery is expected.

3. How Much Does USPS Sunday Delivery Cost?
If USPS decides to deliver your package on a Sunday because of high package volume or local operational needs, you won’t be charged an additional fee beyond your original shipping cost.
However, the cost depends on the mail service you choose.
- As the primary USPS service that offers scheduled Sunday delivery, Priority Mail Express includes 1-3-day delivery with a money-back guarantee and starts at $35.65 at a Post Office. If you specifically request Sunday or holiday delivery, USPS may charge an additional fee in many eligible markets. Availability varies by destination.
- For Priority Mail, USPS Ground Advantage, and other eligible package services, Sunday delivery is generally not guaranteed. Instead, USPS may deliver these packages on Sundays at no extra cost when doing so helps manage increased shipping volume, particularly during the holiday season or in high-demand areas.
4. USPS Sunday Delivery Hours
Delivery hours vary by location, package volume, staffing, and the type of shipping service used. In most areas, Sunday package deliveries typically occur between 9:00 a.m. and 8:00 p.m., although some routes may start earlier or finish later during peak seasons.
If you’re waiting for a Sunday delivery, the most accurate estimated arrival time will appear in your USPS Tracking updates.
5. How to Increase Your Chances of Sunday Delivery
There are several ways to improve the likelihood that your package will arrive before the weekend ends.
- The best way to maximize your chances is to select Priority Mail Express. This is USPS’s fastest domestic shipping service and the only one that offers scheduled Sunday delivery in many eligible markets. It provides 1–3 day delivery with a money-back guarantee.
- To avoid delays, ship your package as early in the day as possible and before the acceptance cutoff at your local Post Office.
- Also consider your destination. Packages traveling to major metropolitan areas are generally more likely to qualify for Sunday delivery.
- Finally, monitor your tracking information regularly, as USPS tracking provides the most accurate estimate of whether your package is expected to arrive on Sunday.

6. FAQs
Why didn’t my eligible package arrive on Sunday?
Sunday delivery depends on local package volume, staffing, processing capacity, and destination. Even eligible packages may arrive on Monday if your area isn’t operating expanded Sunday delivery services.
What days does USPS not deliver?
USPS delivers mail Monday through Saturday nationwide. Sunday delivery is limited to eligible packages in certain areas.
Does “out for delivery” mean “I get it today”?
“Out for delivery” means your package has reached your local Post Office and is with a carrier for delivery today. It may arrive separately from your regular mail and later in the day.
Track your package via text or email updates. If it isn’t delivered after one full postal business day, submit a service request using your tracking number.
Does USPS Ground Advantage deliver on Sunday?
USPS Ground Advantage does not include guaranteed Sunday delivery. However, your package may still arrive on Sunday if USPS expands weekend deliveries due to high package volume or local operational needs, especially during the holiday season or in high-demand areas.
Conclusion
That’s essentially how USPS Sunday delivery works. While you shouldn’t expect regular letters or standard mail to arrive on Sundays, eligible Priority Mail Express shipments and many Amazon or other package deliveries may still show up. Check your tracking status to know if your shipment is scheduled for Sunday delivery.
