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.

With more than 34,000 retail locations and one of the most frequently visited websites in the federal government, usps.com, the Postal Service has an annual operating revenue of more than $71 billion and delivers 48 percent of the world’s mail.
