Telephone customers in western Kentucky soon can begin preparing for the changes that will come early next year when area code 364 is added to the same geographic area as 270.
This eventual change will require people to dial ten-digit numbers in order to connect instead of seven-digit dialing. Kentucky Public Service Commission spokesperson Andrew Melnykovych says a "permissive dialing" period begins Saturday, during which customers will be able to dial either seven or ten digits when making local calls in the 270 area. Mandatory 10-digit dialing begins early next year.
Melnykovych says overlays are the current way new area codes are designated instead of using geographic boundaries.
Area code 364 was created by the PSC when it was decided more telephone numbers are needed in the 270 area. The best way to remember the new area code is that 364 spells “dog” on your keypad.
