About ZIP 37409
ZIP boundaries are postal routes, not tax boundaries.
Chattanooga sits on the Georgia line, where the combined rate drops to about 8% — a meaningful gap on large purchases. For destination-based sourcing, Tennessee sellers should confirm the rate by full street address rather than ZIP alone — a single ZIP can cross a city limit or a transit-district boundary, and the rate follows the boundary, not the mail route.
