The U.S. Postal Service is a self-supporting independent establishment of the executive branch that provides mail and package delivery to every U.S. address. Governance is vested in an 11-member Board of Governors, with day-to-day operations led by the Postmaster General. It is funded mainly by postage and service fees rather than tax dollars, and serves all individuals, businesses, and government users nationwide.
Created by Congress under the Postal Reorganization Act of 1970 (Pub. L. 91-375, 84 Stat. 719; codified at 39 U.S.C. (esp. 39 U.S.C. 201-202)), it acts within the authority that statute grants. Its actions are subject to judicial review and to congressional oversight and funding.
