Cincinnati, founded in 1788, is a city that bears witness to the richness of American history. It was named after the Society of the Cincinnati, a group of officers who served under George Washington during the Revolutionary War. The city's growth coincided with the rise of the steamboat era, and Cincinnati soon became a hub for trade and commerce. It was during this time that the need for a comprehensive telephone network arose, and the Cincinnati area code came into the picture. In 1947, when the North American Numbering Plan was implemented, the Cincinnati area code, 513, was assigned. Today, the Cincinnati area code spans over nine counties in Ohio, and is a testament to the city's enduring legacy of growth and innovation.
