Get ready for the 629.
Nashville and Middle Tennessee will add a second area code, state officials announced Thursday, with the new set of phone numbers rolling out once the existing supply of 615 numbers runs out in about two years.
The Tennessee Regulatory Authority voted unanimously to create the overlay, which will let present customers keep their current numbers. The agency said the decision reflected the results of a survey, which found that 83 percent of respondents favored an overlay over splitting the 615 into two regions.
The switch will require all Middle Tennessee phone users to dial 10 digits, even when calling within the 615 area code. But calls placed to either area code will be considered local, TRA said.
The TRA projects that the first 629 numbers will be issued in spring 2015.
