Priority Mail Express
Priority Mail Express is the fastest USPS service, even offering overnight delivery. Guaranteed delivery in 1-3 days. Learn more about USPS Priority Mail Express.
Priority Mail Express rates are based on parcel weight, dimensions or packaging, distance, and rate class.
When a custom package is used, parcel weight and dimensions are used to determine postage costs. Costs increase as weight and dimensions increase.
Postage costs also increase as the distance increases. USPS uses Zones to measure the distance a domestic shipment must travel, ranging from Zone 1 (local) to Zone 9 (very far away). Learn more about Zones.
In contrast, Flat Rate services require specially marked envelopes that receive one rate, regardless of distance or weight. If items fit, Flat Rate envelopes are often the lowest cost option. USPS provides packaging at no cost.
Commercial Pricing is a discounted postage rate, lower than Retail pricing. It is only available to qualifying shippers, including ShippingEasy subscribers. Learn more about USPS Commercial Pricing.
USPS has added Nonstandard Fees & Dimensional Noncompliance Fees for oversized packages or packages labeled with incorrect dimensions effective April 2022. These surcharges will only apply to domestic residential and commercial addresses.
Flat Rate packages and Regional Rate packages are not applicable.
