A self-supporting government enterprise, the U.S. Postal Service is the only delivery service that reaches every address in the nation — 151 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 32,000 retail locations and the most frequently visited website in the federal government, usps.com , the Postal Service has annual revenue of more than $65 billion and delivers nearly 40 percent of the world's mail. If it were a private sector company, the U.S. Postal Service would rank 35th in the 2011 Fortune 500. In 2011, Oxford Strategic Consulting ranked the U.S. Postal Service number one in overall service performance of the posts in the top 20 wealthiest nations in the world. Black Enterprise and Hispanic Business magazines ranked the Postal Service as a leader in workforce diversity. The Postal Service has been named the Most Trusted Government Agency for six years and the sixth Most Trusted Business in the nation by the Ponemon Institute.
