Area codes 270 and 364

Major cities in the numbering plan area include Hopkinsville, Paducah, Henderson, Murray, Bowling Green, Owensboro, Elizabethtown, and Madisonville.

Mandatory dialing to the new area code was changed as well, but the actual date was to be determined later by the PSC.

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

Eventually, on September 27, 2012, the PSC announced that all number conservation options had been exhausted, and the implementation of 364 could no longer be delayed.

Under the NANPA proposal, existing 270 numbers would be retained by customers, but 10-digit dialing for local calls would be required across western Kentucky.

That includes numbers assigned to wireless devices," said Andrew Melnykovych, Director of Communications for the PSC.

[16] Eventually, on August 3, 2013, the permissive dialing period for the 364 area code commenced and ended on February 1, 2014.
