While I’m working on updating my Zip Code site I would like to provide you with a weekly history lesson about the US Postal System, I hope you enjoy it as much as I did working on it.

The United States Postal Service as we know it today had its beginnings at the birth of the country itself. The mail service has the unique distinction of being one of few governmental agencies explicitly authorized by the United States Constitution, under the so-called “Postal Clause.” Although postal services had been active in the colonies before independence from Great Britain,imagesGBthe service flourished following the establishment of the United States Post Office in 1775. Over the next few decades, the postal service was extended westward, as Congress authorized the construction and establishment of postal routes across the country.
