 Area codes 234 and 330 were originally part of area code 216, one of the original North American Numbering Plan codes.Some of the first 234 numbers were assigned in 2003, when a new FedEx Custom Critical office opened on Boettler Road in Green, Ohio.Area code 234 was planned to become the area code for the Jacksonville, Florida area, but local businesses and the Federal Communications Commission split the existing area code, 904, into area codes 850 and 386.
