Area code 364

From Wikipedia, the free encyclopedia

Approximate planned service area of Area Code 364 is in red.

Area code 364 is a proposed area code to serve western Kentucky, including the cities of Madisonville, Hopkinsville, Henderson, Murray, and Paducah. It will be created by splitting Area code 270 along the counties through which the Pennyrile Parkway passes.

On May 31, 2007, the Kentucky PSC announced that 270 would be split with the newly-created area code, still to be announced, serving western Kentucky, and area code 270 serving west-central Kentucky. This announcement indicated that permissive dialing of the new area code would begin on April 1, 2008, with mandatory dialing to the new area code on October 1, 2008. [1]

The PSC did note that mandatory number pooling, recently imposed on the region, may delay the implementation of the new code. Surprisingly, the 502 and 859 area codes, which serve the urban areas of Louisville (502) and Lexington and Northern Kentucky (both 859), have fewer numbers available than 270, and neither is expected to run out of numbers before 2017.

On June 13, 2007, the PSC announced that the new area code will be 364, but also announced that the previously announced implemention dates would be changed due to number conservation measures including expanded number pooling. [2]

On June 15, 2007, the PSC actually postponed the permissive dialing of the new 364 area code to October 1, 2008. Mandatory dialing to the new area code was changed as well, but the actual date is still TO BE DETERMINED by the PSC. [3]

On November 1, 2007, the PSC again postponed permissive dialing of the new 364 area code, this time to January 1, 2009. Mandatory dialing to 364 is still TBD. [4]

More recently, on March 31, 2008, the PSC even further postponed permissive dialing of the new 364 area code, to April 1, 2010. Mandatory dialing to 364 is still TBD. [5]

These subsequent delays or postponements of the implementation of the 270 / 364 area code split are due to further use of number conservation measures, including mandatory and expanded number pooling.
