About ZIP 37912
ZIP boundaries are postal routes, not tax boundaries.
Knox County's local option rate matches Davidson's, so Knoxville and Nashville charge the same total despite very different budgets. 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.
