Where is area code 423?

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.

The first new area code, 423, was officially launched on September 11, 1995. It was created from a split of area code 615. In 1999, it was split to form area code 865. This prefix (423) covers 26 counties, including Bledsoe County, Bradley County, Campbell County, Carter County, Claiborne County, Cocke County, Greene County, Hamblen County, and Hamilton County, and 50 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.

How does a 423 business phone number work?

A 423 business phone number operates like any other phone number in the USA. It’s obtained through a telecommunications provider, routed to the business’s phone line when dialed and managed by a service provider for communication with customers. It enables global communication while facilitating local calls within the 423 areas. A 423 number can increase trust and establish a local presence even if your business operates virtually like other local numbers.

For example, to call the number 467-6460, you would dial 1-423-467-6460, where 1 is the country code for the USA. The 423 is an area code that directs the calls to the appropriate region, and the 467 is a central office code that routes calls to a specific carrier or service provider. The final 6460 is a subscriber number, identifying the specific business or individual being called.
