6 Important Things to Know About USPS Delivery Times

Before sending your shipment with USPS, it is important to understand the various factors and metrics that can affect delivery. With this inside knowledge, you can accurately predict USPS mail delivery times and provide your customers with estimated delivery times with confidence.

Key Factors Influencing USPS Delivery Times

1. Type Of Service: USPS transit times significantly depend on the type of shipping option that you choose. For instance, choosing to send your domestic shipment with Priority Mail Express ensures an overnight delivery, while USPS shipping times for USPS Ground Advantage can take up to 8 days depending on the destination. USPS Priority Mail Express International, as an express delivery service, will result in faster mail delivery times for international shipments (compared with Priority Mail International mail options which are slower and cheaper for non-urgent deliveries).
2. Calculate by Zip Code: Before selecting a delivery option, take advantage of the free Easyship Shipping Rates Calculator to calculate the expected USPS rates and delivery times. Simply enter the sender location and the intended destination inside the three-step tool to get an instant estimate on how many days USPS delivery will take.
3. USPS Special Delivery Services: For urgent shipments that should be delivered within a given timeframe, compare the expected delivery date within the calculator or inquire about USPS special delivery services for complete peace of mind.
4. Military Destinations: USPS delivery times to military destinations might change based on the prevailing operational conditions of the area. Always be aware of these changes and give yourself as much lead time as possible.
5. Federal Holiday Schedule: As you plan ahead for the 2025 Peak Season, be sure to know the USPS delivery cut-off and pre-Christmas delivery deadlines. USPS holidays are not included in the calculated expected USPS transit times. View our complete list of 11 federal holidays inside our USPS Holiday Schedule here.
6. Weekend Delivery: For most services, USPS only operates and calculates delivery times based on business days (Monday-Friday). However, USPS does offer Saturday delivery on some mail and postage services including Priority Mail and Priority Mail Express. Post Offices generally operate on Saturday's in most locations but with reduced hours. Meanwhile, both Post Offices and full-time postal workers do not work on Sundays. For more weekend delivery options on either a Saturday or Sunday, consider any of our express carrier services like UPS or FedEx which you can compare within Easyship's multi-carrier comparison tools.

Can I Get a Delivery Time Estimate for My USPS Packages?

As mentioned, USPS shipping time varies depending on a broad range of factors. You can get an accurate estimate by understanding the distance between the two locations, the type of mail class chosen, the presence of recognized USPS holidays, and other transport challenges. For example, during the recent Canada Post strike that affected the Canadian postal service for 31 days in November and December 2024, USPS international services were delayed due to the inability for the final-mile partner to accommodate the volume of packages sent.

Taking this point further, if you want to send your shipment using USPS Ground Advantage, it might take between 2 and 5 working days to deliver the package (or up to 8 depending on the final destination's shipping zone). This makes it a reliable option for sending a broad range of items as either small, medium or large boxes, oversized packages, and non-urgent packages. USPS Media Mail also takes the same duration, but is a more affordable shipping alternative for sending books, retail media products and educational materials.

eCommerce businesses looking to deliver standard-sized or single-piece envelopes weighing up to 3.5oz can opt for the USPS first-class mail, which usually takes between 2 and 3 business days.

Worth Paying for USPS Priority Mail Express over Priority Mail for Faster Delivery?

To compare the different delivery times between two of USPS more popular package delivery services - USPS Priorty Mail and Priority Mail Express - consider the following key differences between the services. You'll then be able to review whether or not its worth paying more for USPS express delivery.

USPS Priority Mail delivers your package in 1-3 business days for most domestic shipments. However, this is not not guaranteed by USPS and actual delivery times may vary. The plus side is that Saturday delivery is included at no extra charge where the delivery date is caculkated as a Saturday.

USPS Priority Mail Express offers guaranteed next-day to 2-day delivery by 6pm. This is a genuine money-back guarantee by USPS if your parcel is not delivered by the guaranteed delivery time. In addition, Sunday and (some) holiday delivery dates are available in many locations for an additional fee.

It's worth noting that the scheduled delivery date and delivery times for USPS Priority Mail and USPS Priority Mail Express can vary significantly depending on the shipment origin, delivery destination, and defined drop-off time.

What Is The Delivery Time Estimate For USPS Ground Advantage?

USPS Ground Advantage, first launched in July 2023, offers the combined strength of the former USPS First-Class Package Service, USPS Retail Ground, and USPS Parcel Select Ground.

In most instances, Ground Advantage offers timely delivery of packages inside the United States within 2-5 business days. There have been reports that this may take up to 8 working days depending on the exact circumstances including origin, destination and package type.
