About ZIP 80011
ZIP boundaries are postal routes, not tax boundaries.
Aurora spans three counties — Arapahoe, Adams and Douglas — so the county component depends on which side of the city line an address sits. For destination-based sourcing, Colorado 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.
