931 Area Code Details

931 Area Code Details

The 931 area code was created in 1997 due to growth of the Middle Tennessee region.

The 615 area code which once was all of middle Tennessee, was retained to be just around the greater Nashville locale.. Thus the newly created 931 area code is shaped like a U surrounding the greater Nashville region.  You can think of the area now as most of middle Tennessee except the Nashville area.

Where Is The 931 Area Code?

See the updated map below covering different counties in middle Tennessee.    You can see the light blue "U" shaped new region that corresponds with the area code 931 that is broken out  --  this region right above and within the "U" is the greater Nashville region .

Why Was the 931 Area Code Created?

The 931 area code was created due to the growth of the region.  The below Bellsouth advertisement documents that the growth of both computer modems and fax machines (fax machines needed their own phone numbers) as well as overall population growth had driven the need for expanding the 931 Area Code.

Who Was BellSouth That Created 931 Area Code?

BellSouth, a prominent telecommunications company, played a pivotal role in the telecommunications landscape of the United States, particularly in the Southeast including the 931 area code.. Founded as part of the break-up of the original AT&T in 1984, BellSouth quickly established itself as a leader in the industry. The company was responsible for the introduction and management of various telephone numbering plans, including the one for the 931 region in Tennessee. 

This specific numbering plan was created to meet the growing demand for telephone services and to ensure efficient and organized telecommunications infrastructure. BellSouth's legacy in shaping the communication networks is still evident today, even after its eventual merger with AT&T in 2006, which marked a significant moment in telecommunications history, combining the strengths of two industry giants.

Further expanding out from the baby bells, Verizon is one company that came after a new merger of GET and Atlantic Bell.  The circle comes back around.

Will the 931 Area Code Be Broken Apart just like 615 was?

Currently, there are no publicized plans or announcements regarding any type of split or break apart the area code 931 within Tennessee.  The absence of news or discussions about changes to the region suggests that it will continue to serve its designated region as is, without being broken apart or overlaid code. This situation is subject to change based on future decisions by telecommunications authorities or due to shifting demands in telephone numbering resources

However, given the rapid growth of not only the Greater Nashville region but also the advent of the 2,000 acre "Megasite" in Manchester TN which will drive substantial population growth as well, the future at some point may lead to something new.
