A little history about the 931 area code
The 931 area code came into being in 1997. It was created to provide additional phone numbers to the areas covered by the original 615 area code. So, you could say that 615 is the “parent” of the 931 area code.
Originally, 931 was designed as an “overlay,” meaning that both area codes would serve the same geographic region, and people might have either a 615 or 931 number. However, 931 has since become its own distinct area, and there are currently no active overlays for it.
Unlike some area codes, 931 is not in danger of running out of available numbers anytime soon.

Area code 931 serves Middle Tennessee, including cities like Clarksville, Cookeville, and Columbia. Understanding the location and demographics associated with this area code can be useful to businesses targeting the region, residents seeking to identify callers, and researchers studying population trends.
While we often take them for granted, area codes play a vital role in the North American Numbering Plan. They’re more than just a set of digits; they’re an essential part of how we connect with each other and facilitate communication across geographical boundaries.
