The United States Postal Service (USPS) has a rich history that dates back to 1775 when it was created by the Second Continental Congress and led by Benjamin Franklin. The US Constitution granted the authority to establish post offices and mail roads in 1787 and exercised through the Post Office Act 1792.

USPS has the unique status of an independent executing agency operating like a business. Unlike many government agencies, it does not depend on tax revenue for funding and must compete for clients. Its success depends on maintaining a culture of operational accuracy, delivering world-class performance, delivering superior service, and encouraging innovation.

With any non-military government agency's most significant physical and logistical infrastructure, the USPS is critical in supporting an ever-changing nationwide communications network.

As the largest postal service in the world, USPS delivers more mail and packages than any other post office. It serves over 165 million addresses nationwide, including every state, city, and city. Every person living in the United States and its territories has access to postage products and services, and they pay the same price for a first-class postage stamp regardless of their location.
