419 Area Code in Ohio, United States
Description
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.
