The 423 area code covers Chattanooga and a wide swath of East Tennessee, including Johnson City, Kingsport, Morristown, Bristol, Sevierville, Greeneville, and Seymour. It's the number people across this stretch of the state recognize as local.
423 stands on its own as the area code for these cities. The neighboring 931 code serves a separate part of Tennessee, so calls within the 423 region don't overlap with it.
This part of Tennessee sits mostly in the Eastern time zone, though some nearby areas run on Central time, so it's worth checking the local time before you call. Standard calling and texting rates and hours apply as with any other US number.
