About ZIP 50320
ZIP boundaries are postal routes, not tax boundaries.
Iowa's local option tax is adopted city by city; the Des Moines metro passed a coordinated 1% LOST that applies across most of Polk County. For destination-based sourcing, Iowa 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.
