Area code 615 covers Nashville and surrounding areas in Middle Tennessee. Established in 1954, it originally served a large portion of Tennessee before splits and overlays reduced its territory. Today, it’s synonymous with the country music industry, state government, and Nashville’s rapid urban growth. 615 is frequently used in entertainment branding and tourism. The overlay with area code 629 requires ten-digit dialing. As Nashville thrives, 615 retains its cachet as a code linked with culture, creativity, and commerce.
