Yes, USPS delivers on Sunday, but only for two kinds of packages: Priority Mail Express (in many major markets, for an additional fee) and Amazon packages. Regular mail, First-Class Mail, Priority Mail and USPS Ground Advantage are not delivered on Sundays; they arrive Monday through Saturday.
That split surprises many people, because they see a USPS truck on a Sunday and assume the mail runs every day. Below is what USPS delivers on Sundays, how Priority Mail Express Sunday delivery works, what to expect from Amazon Sunday drop-offs, and what is and isn’t open on the weekend.
What Does USPS Deliver on Sunday?
USPS limits Sunday delivery to Priority Mail Express and Amazon packages. Everything else waits for the next regular delivery day, which is usually Monday.
| Mail type | Delivered on Sunday? | Notes |
|---|---|---|
| Priority Mail Express | Yes, in many major markets | Sunday and holiday delivery costs an additional fee |
| Amazon packages | Yes, in many areas | Delivered under USPS’s agreement with Amazon |
| Priority Mail | No | Delivered Monday through Saturday |
| USPS Ground Advantage | No | Delivered Monday through Saturday |
| First-Class Mail letters and flats | No | Delivered Monday through Saturday |
| Marketing mail, catalogs, bills | No | Delivered Monday through Saturday |

How Does Priority Mail Express Sunday Delivery Work?
Priority Mail Express is USPS’s fastest domestic service, with 1–3 day delivery by 6 PM and a money-back guarantee (exceptions apply under the Domestic Mail Manual). USPS says Sunday and holiday delivery is available in many major markets for an additional fee.
- Delivery commitment: 1–3 days, by 6 PM, depending on the origin and destination.
- Sunday and holiday delivery: available in many major markets, not everywhere, and for an added fee.
- Included features: USPS Tracking and up to $100 of insurance with most shipments.
- Refunds: if USPS misses the guarantee, you can request a refund within 30 days of the mailing date.
Older guides say Priority Mail Express is “guaranteed by 10:30 a.m.” on Sundays. USPS’s current Priority Mail Express page doesn’t list a 10:30 a.m. commitment; it describes delivery by 6 PM. When you buy the label, the Post Office or online checkout shows the actual date and whether Sunday delivery is offered for that ZIP Code.
If you need a package there by Monday morning but Sunday delivery isn’t offered at the destination, compare next-day options across carriers in our guide to overnight shipping.
Does USPS Deliver Amazon Packages on Sunday?
Yes. USPS has delivered Amazon packages on Sundays since 2013, when the two announced a Sunday delivery agreement that started in a few metro areas and later expanded. It’s the main reason you’ll see USPS carriers on residential streets on a Sunday.
Whether your Amazon order arrives on a Sunday depends on Amazon, not on you. Amazon chooses the carrier and the delivery date for each order, and a Sunday estimate in your Amazon order is the best sign that USPS will bring it that day. Our page on Amazon shipping and delivery covers how Amazon’s own network and its carrier partners fit together.
Amazon packages handled by USPS can be tracked in your Amazon order and, with the USPS tracking number, at USPS.com. If you have the number, our USPS tracking ID lookup guide shows where to enter it.
What Time Does USPS Deliver on Sunday?
There isn’t a single Sunday schedule. Priority Mail Express is committed to arrive by 6 PM on its guaranteed date, while Amazon Sunday deliveries follow the local route and package volume, so arrival times vary by neighborhood.
On regular delivery days, USPS’s stated goal is to complete deliveries by 5 PM local time, though that isn’t a guarantee and routes can run later during heavy volume. Our guide to what time mail gets delivered covers typical weekday and Saturday hours.
Does USPS Deliver on Saturday?
Yes. Saturday is a regular USPS delivery day for letters and packages, including First-Class Mail, Priority Mail and Ground Advantage. Priority Mail has no Saturday surcharge, so a Priority Mail or Ground Advantage package can arrive on a Saturday at no extra cost.
That’s also why USPS counts Saturday when it estimates delivery times, while Sunday and federal holidays are skipped for most services. Our guide to does USPS deliver on Saturday covers Saturday hours and services in detail, and our Priority Mail and Ground Advantage delivery-time guide shows how business days are counted.
Are Post Offices Open on Sunday?
Most Post Office retail counters are closed on Sundays. Some locations keep their lobbies open longer, or around the clock, so PO Box holders can reach their boxes, and some lobbies have self-service kiosks for buying postage and dropping off packages.
Hours vary by location, so check the USPS Locator for the specific Post Office before you go. Our guide to whether the Post Office is open on weekends explains Saturday counter hours and Sunday lobby access.
Can you schedule a USPS pickup on Sunday?
No. USPS Package Pickup runs on regular delivery days, so Sunday isn’t available. If you prepare a package over the weekend, you can buy the label online and schedule a free pickup for the next delivery day, which you can do online at USPS.com.
Does USPS Deliver on Holidays That Fall on a Weekend?
On federal holidays, USPS doesn’t deliver regular mail, and Post Office counters are closed. Priority Mail Express can still deliver on holidays in many major markets for an additional fee, the same way it handles Sundays.
When a holiday is observed on a Monday, mail you expected Saturday won’t arrive until Tuesday. Check our USPS holiday schedule for the dates mail delivery stops each year, and our USPS delivery policy guide for how service standards treat weekends and holidays.
How Can You Plan Around No Sunday Delivery?
If a package has to arrive by Monday, ship early enough that a Saturday delivery is realistic, or use Priority Mail Express and confirm Sunday delivery is offered for the destination ZIP Code. Correct addresses matter too, since a bad address can push a package past the weekend; our guide to USPS address correction services shows how to fix one before it ships.
If you’re away over the weekend, USPS Hold Mail lets you pause delivery for 3 to 30 days and get everything delivered when you return. For packages, free shipping resources such as USPS-supplied Priority Mail boxes help you pack ahead and ship first thing Monday.
When you ship, ParcelPath is free to use, with up to 89% off USPS and up to 85% off UPS, and free USPS pickups on delivery days. You can compare Priority Mail Express, Priority Mail and UPS options for your package in the ParcelPath rate calculator.
