Mansfield, OH utilizes an area code overlay in which area codes 419 and 567 serve the same geographic area. The area code overlay which is in use today was established in 2002 at which time area code 567 was created as an overlay of area code 419. Area Code 419 was created in 1947 and was one of the original area codes assigned to Ohio. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
