USPS Services Eligible for Sunday Delivery
Here’s a clear breakdown of which USPS mail classes qualify for Sunday delivery and which do not.
| Mail Class / Service | Sunday Delivery Available? | Details |
| Priority Mail Express | ✅ Yes | Guaranteed overnight to 2-day delivery, including Sundays and holidays in many areas. |

Why Sunday Delivery Is Limited
Despite growing demand for 7-day service, USPS limits Sunday delivery for several important reasons.
1. Operational Constraints
USPS manages one of the largest delivery networks in the world. Adding a full extra day of standard delivery would require increased staffing, transportation costs, and scheduling changes expenses that could outweigh the benefits.
Sunday delivery is therefore reserved for mail classes that are both time-sensitive and generate higher revenue, such as Priority Mail Express.
2. Cost and Efficiency
Delivering mail on Sundays costs more. The USPS focuses its resources on services that justify these expenses, such as overnight shipments and large e-commerce deliveries. Regular mail doesn’t generate enough revenue to make Sunday delivery cost-effective.
3. Strategic Partnerships
The USPS’s partnership with Amazon changed the Sunday delivery landscape. To meet Amazon’s promise of fast delivery, USPS expanded its Sunday operations to include select packages in many metropolitan areas. However, this service is still contract-based and not available for all mail.
4. Regional and Volume Considerations
In densely populated urban areas, there’s more demand for Sunday delivery. In contrast, rural regions often see little to no Sunday service. USPS prioritizes areas where package volume justifies the cost.
How Sunday Delivery Works
If you are expecting a package on Sunday, here’s what you should know about how the process works.
Delivery Hours
- Most Sunday deliveries occur between 10:30 a.m. and 6:00 p.m.
- Deliveries can extend later during busy seasons like December or after major sales events.
- USPS tracking will show “Out for Delivery” once your package is assigned to a route that day.
Post Office Operations
- Most post offices are closed to the public on Sundays.
- While you can’t buy postage or drop off mail, carriers still operate behind the scenes for express and contracted deliveries.
Delivery Costs
- Priority Mail Express includes Sunday delivery at no additional cost in most areas.
- Some locations may charge a small Sunday/Holiday delivery surcharge depending on volume and region.
- Amazon packages delivered on Sunday are covered under Amazon’s existing logistics agreement, not by the sender.

Sunday delivery depends on a few factors:
- Your Location: Sunday service is common in major cities and metro areas, but rare in rural ZIP codes.
- Mail Class: Only Priority Mail Express and Amazon packages qualify.
- Seasonal Demand: During holidays, USPS may expand Sunday delivery to handle increased shipping volumes.
During the busy season, even Priority Mail (not Express) packages might get delivered on Sundays in some high-traffic regions.
Saturday vs. Sunday Delivery
Many people confuse Saturday and Sunday delivery. Here’s how they differ:
| Feature | Saturday Delivery | Sunday Delivery |
| Availability | Standard for most services | Limited (Express and Amazon only) |
| Mail Classes Delivered | First-Class, Priority, Packages | Priority Mail Express, Amazon Packages |
| Post Office Open? | Yes (limited hours) | No (delivery only) |
| Cost | Regular rates | Premium or contracted rates |

USPS has long operated on Saturdays as a normal business day, while Sunday remains a specialized service day.
