How ReportLost Works in Riverside
You file your report
Tell us what you lost, where, and when. We generate a detailed description ready to send to every relevant office in Riverside.
We route it to the right places
Your report goes directly to Riverside Police, RTA Transit Lost & Found, the Animal Shelter if it's a pet, and all active local channels. No more bouncing between phone numbers.
Automated monitoring finds your match
For months after your report, we scan Facebook, Nextdoor, Craigslist, OfferUp, local Reddit threads, and every public post in the Riverside area. When someone posts "found," we cross-check location, description, and timing. The moment a credible match appears, you get an alert.
