Don't wait to start your search
The sooner you file a report, the sooner we route it to the people who can help and the faster your search can begin. Once your report is in, our system takes over the legwork of keeping your information active across all channels.
Report my lost item →Losing something valuable in Calimesa can feel isolating. Your wallet might be turned in to the Sheriff's Department, your pet might show up in a community Facebook group, your keys could be with a local business, but no single place tracks them all. The different systems don't talk to each other, and if you try to cover all the bases yourself, you end up making the same calls and posting the same description over and over.
ReportLost simplifies that. File one report with us, and we make sure the Riverside County Sheriff, Calimesa City Hall, local lost pet networks, and active community channels all get the right information. Then, your report stays active and continues to search for a match automatically for 12 months, matching new found items and posts against your description while you focus on other things. It's the peace of mind that comes from knowing someone's actively looking, not just hoping.
