Historical Timeline of Area Code 364

Area code 364 entered service on March 3, 2014 as Kentucky's first overlay area code, covering western and south-central Kentucky over the existing 270 territory. Originally planned as a geographic split in 2007, the plan was repeatedly delayed by number conservation measures, suspended in 2010, and ultimately replaced by an overlay decision in December 2012. The full regulatory process spanned over six years. Source: NANPA PL-449.

Key milestones:

  • 1947: Kentucky was assigned area code 502 as one of the original 86 North American area codes.
  • 1954: Eastern Kentucky split from 270 to receive area code 606.
  • 1999: Western Kentucky split from 270 to receive area code 270.
  • 2007: The Kentucky PSC decided to split 270 on May 31 (Case 2006-00357). NANPA selected 364 as the new area code on June 12. On the same day, the FCC authorized mandatory thousands-block number pooling in the 270 NPA, freeing hundreds of thousands of numbers. Source: KY PSC
  • 2010: The PSC suspended the split in August and vacated the decision entirely on December 13. Relief was believed to be dead. Source: KY PSC Order
  • 2012: NANPA projected 270 exhaustion by Q1 2014. On December 17, the PSC selected an all-services distributed overlay of 364 on 270, the first overlay in Kentucky history. Source: KY PSC Case 2012-00129
  • 2013: NANPA issued Planning Letter PL-449 on January 29 with the implementation schedule. Permissive 10-digit dialing began August 3.
  • 2014: Mandatory 10-digit dialing began February 1. Area code 364 entered service March 3. Source: NANPA PL-449

Area code 364 shares the same geographic footprint as 270, serving cities including Bowling Green, Owensboro, Elizabethtown, Hopkinsville, Henderson, and Paducah. The code spans both the Central and Eastern time zones.
