Area codes 270 and 364
Area code 270 serves the Commonwealth of Kentucky's western counties. Area code 270 was split from area code 502 on April 19, 1999. Planning for the introduction of a second area code for the region, area code 364, began in 2007; after several years of delay, it was finally announced in December 2012 that the second code would be introduced as an overlay in August 2013, with mandatory 10-digit dialing within the geographic region set to begin on February 1, 2014. Numbers in area code 364 will be available for assignment on March 3, 2014.
On May 31, 2007, the Kentucky Public Service Commission (PSC) announced that 270 would be split along the Pennyrile Parkway, with a newly created area code (later announced to be 364), serving western Kentucky, with 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 of the new area code on October 1, 2008. Among the communities remaining in the 270 area code were: Bowling Green, Owensboro, and Elizabethtown. Communities that were to begin using the 364 area code included Madisonville, Hopkinsville, Henderson, Murray, and Paducah, and the Kentucky portion of the Fort Campbell Army base.
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 implementation dates would be changed due to number conservation measures including expanded number pooling.
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.
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.
On March 31, 2008, the PSC again postponed permissive dialing of the new 364 area code, to April 1, 2010. Mandatory dialing to 364 is still TBD.
More recently, on June 2, 2009, the PSC even further postponed permissive dialing of the new 364 area code, to January 1, 2012. Mandatory dialing to 364 is still TBD. The split was suspended indefinitely on August 13, 2010 with no permissive dialing date. Most recently, in December 2010, relief was suspended completely. The split plan is now[when?] dead, but could be revived (or replaced with an overlay of 270) when necessary.
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, as well as a weakened economy and a reduced usage of telephone numbers dedicated for use by computer and fax modems.
Update 9-27-12: The PSC plans to introduce a new “364” area code in the state’s existing “270” area code region (western part of the state) in order to address an impending exhaustion of numbering resources in the exchange. NANPA projects the 270 region to run dry for new numbers by the first quarter of 2014, said the PSC. The administrator had previously projected that the area code would run out of numbers by the third quarter of 2014. The administrator is recommending that the PSC institute an area code overlay in the existing 270 region. Under the NANPA proposal, existing 270 numbers would be retained by customers, but 10-digit dialing for local calls would be required. The PSC would also consider an alternate proposal to split the 270 area code region. “Splitting the area code in two avoids ten digit dialing but requires changing all current area code 270 numbers within the new area code to 364. That includes numbers assigned to wireless devices,” said. Mr. Melnykovych, Director of Communications for the PSC. The commission plans to hold public meetings throughout the 270 region next month to explain the options and receive public comment. The commission also said that it will accept comments on the industry’s overlay proposal for the 270 region up until Nov. 16th.
