The U.S. Postal Service is the only delivery service that reaches every address in the nation: 160 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.
These principles and objectives endure. While radio, television and the Internet have irrevocably altered our information-gathering habits, postal correspondence remains the most secure and resilient form of communication, providing the American People with a delivery infrastructure vital to our National Security.
