Area code 419 serves northwestern Ohio, including cities such as Toledo, Lima, Findlay, and Mansfield. It is one of the original area codes established in 1947 and has long been a staple of Ohio’s industrial and agricultural regions. In 2002, area code 567 was added as an overlay to provide additional number capacity, requiring ten-digit dialing. The 419 area has strong ties to manufacturing, logistics, and the Great Lakes economy. It also includes a mix of urban centers and rural communities. 419 remains an iconic code in the state and is frequently used in branding, local pride campaigns, and regional media.
