Area Code Breakdown & Regional Mapping
931 – Middle Tennessee (Outer) Code
Area code 931 was created in 1997 when it split from 615, serving the outer ring of Middle Tennessee including Clarksville, Columbia, Cookeville, and Tullahoma. It covers Clarksville and Montgomery County as a single, non-overlaid area code.
Neighborhoods & Local Coverage
Clarksville’s 931 code covers a city anchored by a historic Downtown around the Montgomery County Courthouse and the restored Roxy Theatre, near the confluence of the Cumberland and Red rivers. The campus of Austin Peay State University sits just west of the downtown core.
Beyond downtown, the same code reaches the fast-growing St. Bethlehem commercial district to the east, the residential Sango area to the south, and the neighborhoods tied to nearby Fort Campbell, the U.S. Army post straddling the Kentucky line that is home to the 101st Airborne Division. The 931 code ties Clarksville to the wider Middle Tennessee region.
Local Dialing Rules, Time Zone & International Format
Because 931 is a single area code with no overlay, Clarksville still permits 7-digit dialing for local calls, though 10-digit dialing (area code + number) always works. Nashville to the southeast uses 615/629.
A note on Tennessee time: Clarksville sits in the Central Time Zone, like the rest of Middle Tennessee. Only the eastern third of the state — Knoxville, Chattanooga, and the Tri-Cities — is on Eastern Time, an hour ahead.
To call Clarksville from outside the United States, dial your country’s exit code, then the U.S. country code +1, followed by the 10-digit number (for example, +1 931 XXX-XXXX). From inside the U.S. and Canada, simply dial 1 before the 10-digit number for long-distance calls.
Major ZIP Codes Covered
The 931 service area spans many of Clarksville’s core ZIP codes, including 37040, 37042, and 37043.
Spam & Scam Call Warnings in Clarksville
Clarksville residents report spoofed 931 robocalls impersonating utilities like CDE Lightband, the IRS, and delivery services. Military-targeted scams around Fort Campbell — including fake-loan and impersonation schemes — are also common.
| Scam Type | What to Watch For |
|---|---|
| Neighbor Spoofing | Calls that mimic a local 931 prefix to look familiar. |
| Utility / Toll Scams | Threats to shut off power or demand toll payment via gift cards. |
| IRS / Government | Robocalls claiming legal action — agencies never call to demand instant payment. |
Red flag: Any caller who pressures you to pay immediately with gift cards, wire transfers, or cryptocurrency is almost certainly running a scam. Hang up and verify through an official number.
