About ZIP 83702
ZIP boundaries are postal routes, not tax boundaries.
Idaho permits local option sales taxes only in designated resort cities; Boise is not one, so the state rate stands alone. For destination-based sourcing, Idaho 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.
