220 Area Code
The 220 area code is a relatively new telephone code in the North American Numbering Plan (NANP). It was introduced in 2015 as an overlay to the existing 740 area code in eastern and southeastern Ohio. This overlay was created to meet the growing demand for phone numbers in the region. The 220 and 740 codes now serve the same geographic area, meaning residents and businesses may have either code depending on when their number was assigned.
Understanding the 220 Area Code
Area code 220 covers much of eastern and southeastern Ohio, including small cities, rural communities, and some suburban areas outside of Columbus. Because it is an overlay, 10-digit dialing is mandatory for all calls within the 220/740 service region.
