The United States Postal Service is an independent federal establishment, mandated to be self-financing and to serve every American community through the affordable, reliable and secure delivery of mail and packages to more than 170 million addresses six and often seven days a week. Overseen by a bipartisan Board of Governors, the Postal Service is currently pursuing a transformation plan aimed at restoring long-term financial sustainability, improving service, and maintaining the organization as one of America’s most valued and trusted brands.

The Postal Service generally receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
