How it works
You report the loss
Tell us what you lost, where, and when. We gather the details that matter for police, shelters, and transit recovery teams.
We route it to the right places
Your report goes straight to Fremont Police Property & Evidence, Tri-City Animal Shelter (if applicable), AC Transit Lost and Found, and gets posted to local found-item channels so recovery teams see it immediately.
Automated monitoring finds matches for you
We search public postings, marketplace listings, and local social channels continuously for 12 months. The moment someone posts "found" matching your description, location, and date, you get an alert—no need to check Facebook groups or Nextdoor daily.

Report my lost item →Losing something in Fremont means contacting the police department, checking transit databases, coordinating with animal services if it's a pet, and then manually scanning local Facebook groups and Reddit for weeks. That's fragmented, exhausting, and easy to miss a match buried in dozens of posts.
ReportLost simplifies it. One form, and we notify every relevant office and monitoring channel in Fremont at once. Then we do the heavy lifting: our system sweeps the web continuously, cross-referencing description, location, and timing against new "found" posts across social media, marketplace apps, and lost-pet networks. You report once and can breathe easy—the search runs 24/7 until we find a lead.
