For many shippers and recipients, Sunday delivery can be a game-changer—especially when you need a package to arrive at your door before the workweek begins. But does the U.S. Postal Service (USPS) deliver on Sundays? The short answer is yes—but only for specific services and under certain conditions. In this article, we’ll break down exactly which mailpieces move on Sundays, how you can keep tabs on your delivery with USPS tracking, get real-time updates via USPS Informed Delivery, and use USPS tracking package features to stay informed every step of the way.

Which USPS Services Deliver on Sunday?

Unlike private carriers, USPS does not offer blanket Sunday delivery for all mail. Instead, Sunday service is limited to:

· Priority Mail Express: USPS’s fastest domestic service guarantees overnight to two-day delivery, including Sundays in many markets.
· Amazon Packages: Under a partnership with Amazon, certain eligible parcels qualify for Sunday delivery at no extra charge.

All other classes—such as First-Class Mail, Priority Mail (standard), and Retail Ground—do not receive regular Sunday delivery. If you’re sending documents, standard boxes, or catalogues, expect them to resume transit on Monday.

Where Is Sunday Delivery Available?

Sunday delivery of Priority Mail Express and Amazon-fulfilled parcels is not nationwide. It’s primarily available in major metropolitan areas where USPS has higher volumes and the infrastructure to support weekend operations. Before you ship:

1.Check Availability: Use the USPS website or call your local Post Office to confirm if your ZIP code is eligible.
2.Consider Timing: Even in eligible markets, packages must be tendered early enough in the week to enter the Sunday network.

How to Track Your Sunday Delivery

Once you’ve sent a package with an eligible service, keeping an eye on its status is simple:

· USPS Tracking: Every Priority Mail Express label includes a unique tracking number. Enter it on the USPS Tracking page to see in-transit updates, departure scans, and delivery confirmation.
· USPS Tracking Package Alerts: Opt in for text or email notifications to receive automatic status changes. These brief alerts tell you when your package ships, arrives at local facilities, and is out for delivery—even on Sundays.

USPS Informed Delivery: Your Sunday Snapshot

For recipients, USPS Informed Delivery offers a convenient way to preview your incoming mail, including any scheduled Sunday items:

1.Sign Up Online: Create a free account at USPS.com and verify your address.
2.Daily Digest Emails: Each morning, you’ll receive grayscale images of your letter-size mail and a list of packages arriving that day.
3.Interactive Notifications: Click directly from your email to see detailed scans, track parcels, and, if needed, arrange redelivery.

Even if you’re away from home over the weekend, Informed Delivery keeps you looped in so you can make plans around any Sunday drop-offs.

Our experience with Sunday Delivery:

· Label Correctly: Ensure your Priority Mail Express label is complete; missing or illegible addresses can delay service.
· Pay the Surcharge: Sunday and holiday delivery carries an extra fee (the “Sunday/Holiday Delivery Premium”). Double-check rates when you purchase postage.
· Use Drop-Off Points: If you miss your carrier’s Sunday pickup, many Post Office branches and self-service kiosks remain open on Sundays for Priority Mail Express.
· Verify with USPS Tracking Package Tools: Revisit your tracking link throughout the day—Sunday scans can come later in the afternoon once carriers finish local routes.
