July 26th, 2014 is the 239th Birthday of the U.S. Postal Service. The Post Office (which was later renamed the U.S. Postal Service) was officially established at the Continental Congress in Philadelphia on July 26th, 1775. Benjamin Franklin was named the first postmaster general and held that position when the Declaration of Independence was signed almost a year later. That makes the Post Office older than the USA. Happy Birthday!
