USPS Sunday delivery is limited and varies by service. Here’s the straightforward breakdown:
- Most mail classes (First-Class Mail, Priority Mail, Retail Ground) are not guaranteed Sunday delivery. When Sunday service is available, it’s typically for time-sensitive or special services, and eligibility depends on local carrier routes and staffing. Expect most Sunday activity to be limited or non-existent for general mail.
- Priority Mail Express on Sundays: If you purchase Priority Mail Express, USPS offers Sunday delivery in many areas, with a money-back guarantee if delivery is not by the guaranteed window. The general guarantee for Express on Sundays has a latest delivery target (often by 6:00 PM local time) with an earlier promised arrival (often around 10:30 AM) in many cases, though exact windows can vary by location. A guaranteed Sunday arrival claim can be filed if not delivered by the guaranteed time.
- Amazon and certain carriers: Amazon shipments and some carrier-specific packages may have broader Sunday delivery windows, sometimes extending later into the evening. This is separate from USPS general service standards and can be time-window-driven by Amazon’s logistics and carrier arrangements.
What to expect if you need Sunday delivery:
- If you require delivery on Sunday, the most reliable option is Priority Mail Express, recognizing there may be an added Sunday delivery fee in some cases, and ensuring you select Express service for time-sensitivity. Check local service standards for your zip code for precise windows.
- For non-Express USPS mail, Sunday delivery is not guaranteed and most items are scheduled for delivery Monday through Saturday, with actual times varying by route and local conditions.
