Overview: USPS Saturday Delivery for Amazon
USPS delivers Amazon packages on Saturdays as part of its standard service agreement with Amazon. Whether it's USPS Ground Advantage, First-Class Package Service, or Priority Mail, Amazon customers often receive weekend deliveries thanks to USPS's six-day delivery schedule.
Historical Context
USPS has maintained six-day delivery service since its inception. This tradition was formally preserved under the Postal Service Reform Act of 2022, which mandated six-day mail delivery as a permanent fixture in its operations. This means Saturday deliveries are not just common—they're federally supported.

- USPS Ground Advantage – Standard delivery used for most Amazon packages
- Priority Mail – Expedited service for time-sensitive orders
- Parcel Select – Used in last-mile delivery from Amazon to USPS
These all support Saturday delivery at no extra charge.
Does Amazon Offer Saturday Delivery?
Yes, Amazon does offer Saturday delivery—and it’s not just limited to Prime members. Thanks to Amazon’s close integration with USPS and its own logistics network, many orders now arrive on Saturdays as part of the standard delivery process.
If your order ships via USPS, it may automatically qualify for Saturday delivery, depending on your shipping speed and location. In metro and suburban areas, same-day and next-day delivery options are also available for eligible products—even on weekends.

Do Amazon Prime Orders Arrive on Saturday via USPS?
Absolutely. USPS delivers Amazon Prime packages on Saturdays, provided the selected shipping speed supports it. Here are the typical options:
- Same-Day Delivery (in select cities)
One-Day Shipping - Two-Day Shipping
Amazon uses a mix of USPS and its internal delivery fleet to route packages efficiently based on your location, the product’s availability, and real-time logistics capacity.
What is USPS Delivery Hours on Sunday?
Sunday delivery is not part of USPS's regular service—unless it's Priority Mail Express or a contracted delivery via Amazon. This means that most USPS mail types won’t be delivered on Sundays, but if you're tracking an Amazon order, there’s a strong chance it could still arrive.
USPS typically delivers Amazon packages on Sundays between 9 AM and 7 PM, depending on volume and location.
Exceptions and Limitations
While Saturday delivery is widespread, it's not universal across all USPS services or geographic regions. Here’s where limitations come into play.
1. Non-Deliverable Services on Saturdays
The following USPS services generally do not include Saturday delivery:
- Media Mail
- USPS Retail Ground
These options are slower and more economical, but they skip weekends in many regions.
2. Geographic Variations
Some rural or remote locations may experience limited Saturday delivery options due to staffing or logistical constraints. Delivery hours may also vary significantly based on local demand and seasonal mail volume.
3. Holiday Considerations
No mail delivery on federal holidays, even if it falls on a Saturday. Always consult the USPS holiday calendar if you're shipping around long weekends.

How to Ensure Saturday Delivery?
Want to guarantee your package hits the doorstep on Saturday? Here’s how to plan and ship accordingly.
1. Choosing the Right Service
Select a USPS mail class that includes weekend service:
- Priority Mail: For free Saturday delivery.
- Priority Mail Express: For time-sensitive packages with guaranteed Saturday or Sunday delivery.
2. Labeling and Scheduling
Double-check that:
- Your shipping label is clear and compliant.
- You drop off packages before the USPS cutoff time, typically around 2 PM local time.
This ensures your item makes it onto the correct delivery route.
3. Tracking Amazon Deliveries Shipped via USPS
When Amazon uses USPS for final delivery, tracking updates may show a handoff—meaning the package has moved from an Amazon facility (or a partner carrier) to the U.S. Postal Service.
To stay fully informed:
- Use the USPS tracking number provided on your Amazon order page to track progress directly on the USPS Tracking website.
- Cross-reference with your Amazon order page for additional updates on both Amazon and USPS—sometimes one updates faster or contains more detailed delivery notes than the other.
- If your package is marked as delivered by Amazon but you haven’t received it, check the USPS tracking history for a more precise timestamp or delivery note (like “left in mailbox” or “front porch”).
This dual-check approach gives you the most accurate and up-to-date information—especially during busy shipping periods or when deliveries span multiple carriers.
Pro Tip: If tracking shows “Transferred to USPS,” your package is still en route and should update shortly on USPS.com.
Amazon & USPS: Latest News and What It Means for Your Deliveries
The logistics landscape is changing fast, and staying ahead of those changes can help you avoid shipping surprises—especially on weekends.
Here’s what’s happening now between USPS and Amazon, and how it affects Saturday and Sunday deliveries:
1. USPS Still Powers Weekend Deliveries—But Strategically
While Amazon has expanded its own delivery network (Amazon Logistics), it still leans on USPS for crucial last-mile coverage—especially in rural areas, apartment complexes, and PO box deliveries. USPS remains a key partner for Saturday and even Sunday drop-offs, particularly for Prime orders.
What it means for sellers and buyers:
If your package is marked “shipped with USPS,” expect delivery on Saturdays—and even Sundays in select ZIP codes. But in rural areas or non-Prime orders, allow an extra buffer day.
2. Automation and Route Expansion at USPS
USPS has been upgrading its infrastructure with AI-powered route planning and sorting machines to keep up with Amazon’s growing package volume, especially over weekends.
Between 2020 and 2022, USPS installed 249 new high-speed package sorting machines, boosting its daily package processing capacity to 60 million—surpassing the highest daily volume recorded during the 2022 peak season by over 10 million packages. (Source)
What it means:
Weekend deliveries are now faster and more predictable, but surges during sales events like Prime Day or Black Friday can still stretch capacity.
3. Amazon Logistics Is Growing—But Has Gaps
Amazon’s own delivery arm is expanding rapidly in urban markets, handling more of its own two-day and same-day shipments. However, Amazon still relies on USPS to cover areas where its logistics arm can’t reach efficiently.
To reduce this reliance, Amazon is investing $4 billion to triple its rural delivery network by 2026—adding 200+ delivery stations, reaching 13,000+ zip codes, and covering 1.2 million square miles (Reuters).
Key takeaway:
Even as Amazon builds its fleet, USPS will remain critical for hard-to-reach locations and non-Prime orders. For sellers, this means you may not have full control over which carrier gets assigned—but it’s worth understanding their strengths.
