Why can't I just use the ZIP code?

  • There are often multiple sales tax rates per ZIP code, county, and city.
  • ZIP codes often overlap, or become subsets of other ZIP codes, or represent no geographic region at all.
  • ZIP codes aren't stable. In any given year, the USPS makes numerous boundary changes to ZIP code areas.

For the most accurate sales tax rate, use an exact street address.
