What Is Shipping?
Shipping is a fundamental part of the USPS, and it's essential to understand the basics.
The history of shipping dates back to the Postal Act of 1792, signed into law by George Washington, which established the USPS and allowed for reduced postage rates for mail that offered societal benefits.
Newspapers were among the first to take advantage of this allowance, and a class structure of postage rates was introduced in 1894.
The USPS has continuously evolved over the years, with the introduction of Priority Mail in 1968, which quickly became a popular alternative to Priority Mail Express.

Each Priority Mail Flat Rate Box and Envelope features one low flat rate, so pricing is determined by the box or envelope you choose, not by the weight or distance the package is traveling.
