How Priority Mail Express Works
Sending a package with Priority Mail Express is simple and accessible. Customers can go to a local post office or use the USPS website to prepare and pay for shipping. Packages can be dropped off or scheduled for free pickup, depending on your preference.

Priority Mail Express is also compatible with Click-N-Ship, USPS’s online label creation tool, making it even easier to send items without visiting the post office.
Pricing for Priority Mail Express
Pricing is based on several factors including package weight, dimensions, and destination. However, USPS also offers a flat-rate option, allowing you to ship packages up to a certain weight for one set price regardless of distance.
Flat Rate vs. Weight-Based Pricing
- Flat Rate: Offers predictable pricing with no need to weigh or measure the package
- Weight-Based: Charges depend on the item’s weight and shipping zone
For lightweight and small items, the flat-rate envelope is usually the most cost-effective choice. Businesses often benefit from commercial rates, which are discounted versions of standard pricing, especially when buying postage online or through shipping software.
Delivery Time and Service Commitments
One of the strongest advantages of USPS Priority Mail Express is its guaranteed overnight delivery to most ZIP codes in the U.S. For more remote locations, delivery may take up to two days, but USPS clearly marks which destinations qualify for the overnight guarantee.
Delivery Time Guarantees
- Delivery typically by 10:30 a.m. the next day to many destinations
