What is what area code is 606?

The 606 area code is a telephone area code in the North American Numbering Plan (NANP) that covers the eastern part of the state of Kentucky in the United States. It was established in 1954 as one of the original area codes assigned in Kentucky.

The 606 area code covers cities and towns such as Ashland, Morehead, Hazard, Pikeville, and Somerset. It serves counties in eastern Kentucky such as Boyd, Carter, Floyd, Johnson, Lawrence, Perry, and Rowan.

The 606 area code is located within the Eastern Time Zone and is bordered by area codes 859, 304, and 423. In 2014, due to increased demand for telephone numbers, the 606 area code was overlaid with area code 859. As a result, new telephone numbers in the 606 region may now be assigned with either the 606 or 859 area codes.
