About ZIP 92504
ZIP boundaries are postal routes, not tax boundaries.
Riverside's Measure Z is a one-cent general tax renewed by voters; without it the city would sit at the county's 7.75%. For destination-based sourcing, California 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.
