As the U.S. Postal Service continues its evolution as a forward-thinking, fast-acting company capable of providing quality products and services for its customers, it continues to remember and celebrate its roots as the first national network of communications that literally bound a nation together. Ours is a proud heritage built on a simple yet profound mission: Connect every American, every door, every business, everywhere through the simple act of delivering mail. This idea of universal service is at the heart of the $900 billion industry that drives commerce, plays an integral part in every American community and remains the greatest value of any post in the world. This is the promise and potential of the United States Postal Service. The Postal Service delivers more mail to more addresses in a larger geographical area than any other post in the world. The Postal Service delivers to more than 151 million homes, businesses and Post Office boxes in every state, city, town and borough in this country. Everyone living in the U.S. and its territories has access to postal products and services and pays the same postage regardless of their location.
Washington, D.C., is governed by a mayor and a 13-member city council. However, the United States Congress has supreme authority over the city and may overturn local laws. Residents of the District therefore have less self-governance than residents of the states. The District has a non-voting, at-large Congressional delegate, but no senators. D.C. residents could not vote in presidential elections until the ratification of the Twenty-third Amendment to the United States Constitution in 1961.
