Area code 423 is located in Tennessee which is in the Eastern and Central time zone. It is the area code for central Tennessee, north and south of Knoxville. This area code covers two separate regions, northeast and southeast. In the northeast, you’ll find cities like Bristro, Johnson City, and Kingsport, whereas in the southeast, you’ll find cities including Chattanooga, Cleveland, and McMinnville. Officially introduced on September 11, 1995, area code 423 was created by splitting area code 615. In 1999, it was further divided to form area code 865. The 423 area code now covers 26 counties such as Bledsoe, Bradley, Campbell, Carter, Claiborne, Cocke, Greene, Hamblen, and Hamilton, serving major cities including Johnson City, Kingsport, Cleveland, Morristown, and Bristol. The Tennessee Public Utility Commission has approved area code 729 as an all-services overlay for area code 423, with an implementation date of March 5, 2025. Area code 729 will become available to subscribers once all assignable central office codes in area code 423 have been assigned. More importantly, ten-digit dialing (area code + seven-digit number) will be necessary for the 423/729 overlay because different homes in the same geographic area can have the same seven-digit phone number, but each would have a different area code.
