Area code 606

Area code 606 serves Kentucky, including Corbin, Pikeville and Ashland (Eastern and Central time). It has been in service since January 1, 1955.

Numbers starting with 606 drew 1,042 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 320 complaints to the FCC since November 2023. The number on your screen can be faked, so a 606 number proves nothing about where a call came from.

Phone companies holding 606 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 62% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
