Area Code 270 History:
Area code 270 was put into service. Area code 270 was created from a split of area code 502.
On March 3, 2014 area code 364 was put into service as an area code overlay of area code 270. Effective February 1, 2014 ten digit dialing in the 364 and 270 area codes became mandatory.
Ten digit dialing (area code + seven digit number) is necessary in the 364/270 overlay 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.
