The U.S. Postal Service delivers mail for America. In an increasingly digital world, the Postal Service remains part of the bedrock infrastructure of the American economy, serving its people and businesses, and connecting the nation together. The core function of the Postal Service is to provide the secure, reliable and affordable delivery of mail and packages to every address in the United States, its territories and its military installations worldwide.

The Postal Service delivers more mail to more addresses in a larger geographical area than any other post in the world. Delivering to more than 157 million addresses in every state, city and town in the country, everyone in the U.S. and its territories has access to postal products and services and pays the same for a First-Class postage stamp regardless of location.
