💨 Abstract

The U.S. Postal Service celebrates its 250th anniversary. Established in 1775, it predates the United States and played a crucial role in unifying the colonies. Starting with Benjamin Franklin as postmaster, it grew to deliver mail nationwide, employing over 635,000 people. The postal service innovated over centuries, from horseback rides to airmail and introducing ZIP codes to modern mail.
