What is Priority Mail Flat Rate?

Priority Mail Flat Rate is a 1 to 3 day shipping service provided by the U.S. Postal Service (USPS) that features one flat rate for delivery of a package or envelope to its destination. The service allows a maximum weight of 70 lbs. or less for each envelope or package. Priority Mail Flat Rate includes free shipping supplies available at the Post Office or sent directly to your residence or business for no charge. Packaging options include three types of envelopes and six boxes in various sizes.

Flat rate pricing eliminates the need to weigh packages or calculate shipping fees, as long as the package weighs less than 70 lbs. Each Priority Mail Flat Rate Box and Envelope features one low flat rate, so pricing is determined by the box or envelope you choose and not by the weight or distance the package is traveling.
