History of 423 Area Code
Area code 423 started serving Tennessee on September 11, 1995, and is the only one that serves this area. It was one of 14 area codes introduced that year.
423 is Tennessee’s third area code, which currently has seven. It was created to relieve the pressure on the 615 area code, as its numbers were insufficient to meet the demand for new numbers.
Moreover, the 615 phone area code was split in 1999, requiring some phone numbers to be updated to area code 865.
Additionally, area code 729 has been proposed as an overlay for the 423 area code, which is expected to go into service on March 5, 2025. However, future plans may change.
