931 Area Code: Clarksville, Tennessee

The 931 area code covers central and southern Tennessee outside the immediate Nashville metro, with Clarksville as the primary city in the directory's records. Clarksville sits along the Cumberland River in northern middle Tennessee, immediately adjacent to Fort Campbell — one of the largest Army installations in the country, home to the 101st Airborne Division and straddling the Tennessee–Kentucky line. The military presence shapes a substantial slice of the local population and economic profile alongside Austin Peay State University and a long-running role as the regional commercial center for the surrounding counties. The 931 footprint extends through Cookeville (Tennessee Tech), Columbia, Tullahoma, and the surrounding cluster of small cities and rural counties of central and southern Tennessee.

Records linked to 931 numbers in the directory often include Chattanooga, Jackson, Knoxville, and Memphis — Tennessee cities outside the 931 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Tennessee and addresses linked across multiple cities. The directory currently documents 355 distinct prefixes within 931 in detail, a working subset of the prefix population the code carries.

Clarksville's median age sits well under the US figure, at roughly thirty, a pattern shaped heavily by the substantial military and military-family population at Fort Campbell. Median household income runs below the national reading, home values come in close to the US median, and population places Clarksville among the larger cities in Tennessee — substantial enough to anchor a regional economy organized around the military installation, the university, and the surrounding small cities and farming counties.
