Neighborhoods & Local Coverage
Franklin’s 615/629 codes cover a city famous for its charming Main Street, a National Register historic district lined with 19th-century storefronts, restaurants, and the restored Franklin Theatre.

As part of Greater Nashville, Franklin shares the 615/629 codes with the capital and its suburbs.
Local Dialing Rules, Time Zone & International Format
Franklin and the 615 region have required 10-digit dialing since the 629 overlay launched — always dial the area code plus the 7-digit number. Neighboring Nashville and Murfreesboro share the same 615/629 codes.
A note on Tennessee time: Franklin sits in the Central Time Zone, like the rest of Middle Tennessee. The eastern third of the state — Knoxville, Chattanooga, and the Tri-Cities — is on Eastern Time, an hour ahead.
To call Franklin 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, +1 615 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 615 service area spans many of Franklin’s core ZIP codes, including 37064, 37067, 37069, and 37135.
Spam & Scam Call Warnings in Franklin
Franklin residents report neighbor-spoofing robocalls faking a local 615 prefix, plus tech-support and fake-investment scams targeting the area’s affluent households. Fake utility-shutoff and delivery scams are also common.
| Scam Type | What to Watch For |
|---|---|
| Neighbor Spoofing | Calls that mimic a local 615 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. |
