About ZIP 73103
ZIP boundaries are postal routes, not tax boundaries.
Oklahoma cities depend on sales tax for general operations because they cannot use property tax for it, which is why municipal rates are unusually high. For destination-based sourcing, Oklahoma 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.
