A self-supporting, independent federal agency, the U.S. Postal Service is the only delivery service that reaches every address in the nation: 155 million residences, businesses and Post Office Boxes. The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
The Postal Service mission is to provide a reliable, efficient, trusted and affordable universal delivery service that connects people and helps businesses grow. Everyone living in the United States and its territories has access to postal products and services and pays the same for a First-Class postage stamp regardless of their location.
