About ZIP 85018
ZIP boundaries are postal routes, not tax boundaries.
Phoenix applies a higher city rate to some categories, including a separate rate tier on retail sales of single items above a threshold. For destination-based sourcing, Arizona 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.
