Saturday: Post Office Hours and Mail Delivery
Saturday is a regular business day for USPS when it comes to mail delivery. Your letter carrier will run their route just like they do Monday through Friday. The main difference is that post office lobbies have shorter hours.
Post Office Hours on Saturday
Most post offices open around 9 AM and close between 12 PM and 2 PM on Saturdays—much shorter than the typical weekday hours of 8 AM to 5 PM. However, hours can vary quite a bit depending on location:
- Urban post offices in busy areas often stay open later, sometimes until 2 PM or 3 PM
- Suburban locations typically close around noon or 1 PM
- Rural post offices may have even more limited Saturday hours, or might not be open at all
Important: Always check your specific post office using the USPS Location Finder at usps.com before making a trip. Hours can change, especially during holidays.

Sunday: What’s Open and What Gets Delivered
Sunday is where things get more limited. Post offices are closed, and regular mail delivery doesn’t happen. But that doesn’t mean everything stops.
Post Offices Are Closed on Sunday
Almost all USPS post office lobbies are closed on Sundays. You won’t be able to speak with a clerk, buy stamps at the counter, or pick up held packages from the service window.
However, there are a few things you can still do:
- Self-Service Kiosks (SSKs): Many post offices have automated kiosks in their lobbies that operate 24/7 or during extended hours. You can buy stamps, weigh packages, and print shipping labels.
- PO Box access: If your post office lobby is unlocked, you can usually access your PO Box on Sundays.
- Mail drop boxes: Blue collection boxes outside post offices accept mail 24/7. Mail dropped on Sunday will be picked up Monday morning.
What USPS Delivers on Sunday
Even though post offices are closed, USPS carriers are out delivering certain packages on Sundays. Here’s what can arrive at your door:
1. Priority Mail Express
This is USPS’s fastest service—overnight delivery to most locations. Priority Mail Express is the only USPS service that guarantees Sunday delivery. If your package is late, you can apply for a refund.
Packages typically arrive by 10:30 AM on Sundays, though some areas see delivery as late as 3 PM. Rural or remote areas may not be eligible for Sunday delivery at all.
Cost: Priority Mail Express starts at $26.75, plus an additional $12.50 Sunday delivery fee.
2. Amazon Packages
USPS has a partnership with Amazon to deliver packages on Sundays. This is especially common in urban and suburban areas. If you’ve ever received an Amazon order on a Sunday, there’s a good chance USPS brought it.
Amazon Sunday deliveries typically arrive between 9 AM and 8 PM. This service is available at no extra cost—it’s built into Amazon’s shipping rates.
What Does NOT Get Delivered on Sunday
- First-Class Mail (letters, bills, postcards)
- Regular Priority Mail (not Express)
- USPS Ground Advantage
- Media Mail
- First-Class Packages
If you’re expecting any of these, you’ll need to wait until Monday.
