New area code to be established in western Kentucky

Posted: Updated:

LOUISVILLE, KY. (WDRB) -- A new area code, 364, will be used in the same parts of western Kentucky as the current 270 code.

Kentucky's Public Service Commission says it was looking at the option that would cause the least disruption for customers and the least cost for businesses.  This is the first area code in Kentucky to be created by what's called an "overlay."  Area code 270 was created in 1999 by splitting area code 502.

"This decision means that everyone who now has an area code 270 phone number can keep that number," PSC Chairman David Armstrong said. "The only thing that will change is that 10-digit dialing will be required for local calls beginning in early 2014."

The PSC says public comments supported the overlay overwhelmingly over the option of splitting the 270 area code.  "Public opinion has shifted dramatically in the six years since the PSC last considered this matter," Armstrong said. "It appears that the public is much less concerned about 10-digit dialing than about the possibility of having to change phone numbers."

Wireless devices and, possibly, increased economic activity are said to be driving the demand.

From the Kentucky Public Service Commission:


1. All current area code 270 numbers remain unchanged. Everyone with a 270 area code number can keep it. Nobody is required to change their area code or phone number.

2. The overlay affects both landline and wireless services.

3. Area code 364 will be overlaid on top of area code 270. That means that area codes 270 and 364 will occupy the same physical space beginning March 2014.

4. In order to distinguish between phone numbers with area code 270 and those with area code 364, 10-digit dialing will be required for all local calls within the overlay.

5. Ten-digit dialing also will be required for local calls into or out of the overlay in those areas that now allow seven-digit  local calling across the area code 270 boundary.

6. Ten-digit dialing means dialing the area code before dialing the number itself – for example: 270-555-1212 or 364-555-1212.

7. Long-distance calls within the overlay will require 11-digit (1-plus) dialing, just as long distance calls to other area codes do now.

8. A transition period, known as permissive dialing, will begin on August 3, 2013 and end on January 31, 2014. During that time, local calls can be made using either seven-digit or 10-digit dialing.

9. On February 1, 2014, 10-digit dialing for local calls will become mandatory in the area code 270/364 territory.

10. Numbers with area code 364 may be distributed beginning March 3, 2014. Telecommunication service providers may continue to distribute 270 numbers for as long as they have any remaining in their inventories.
