The state of Ohio is divided into twelve area codes; Ohio's 283 code is an overlay area code which means it serves the same geographic area as one or more existing area codes. The 283 covers the same geographical area as the 513 and 248 area codes. The overlay system requires that all calls within the area be dialed with the area code, regardless of the number origin.
