Area code 220 is an overlay of area code 740 and serves central and southeastern Ohio. This region includes cities such as Newark, Lancaster, Zanesville, and Marietta. Introduced in 2015, area code 220 was created to accommodate the growing demand for new phone numbers in this primarily residential and rural area. Known for its scenic landscapes, historic towns, and strong community values, the 220 area supports a blend of small-town charm and access to outdoor recreation, while remaining within reach of the Columbus metropolitan area.
