Who is reading your plate?
County by county.

Wisconsin has no state law governing plate readers, and Attorney General Josh Kaul called on the Legislature in September 2026 to pass one; of the 89 Wisconsin agencies on this map with documented programs, 33 have ended them and 9 have paused them.

How this map is built

We start with each county’s sheriff’s office and its largest city police departments, then work outward. Each agency’s entry says whether it comes from agency records or from news reports, and links every source. Companies are tracked separately, so the map can show one company’s customers or all license-plate readers together.
