KNOXVILLE, Tenn. — A new 729 area code will be introduced in East Tennessee, including in the Tri-Cities region, officials announced Monday.
According to the Tennessee Public Utility Commission, the current 423 area code will run out of numbers by the end of 2025. They said that the commission approved the new area code on May 30.
Officials said existing customers will keep their current area code and phone number. New customers or additional lines may be assigned the 729 area code once it is activated. That specific date has not yet been announced.
People will also need to continue using ten-digit dialing, typing in the area code as well as the seven-digit phone number, to make calls.
