Don't let your lost item fade into the system.
The sooner you file a report, the sooner all channels start looking. Once your report is submitted, your part is done—our team and their systems take it from there, and your report keeps working for you.
Report my lost item →Losing something in Clayton—whether at home, work, in a local shop, on the way to Lambert Airport, or while using Metro Transit—means hunting across multiple channels: the police department, animal shelters, transit customer service, and scattered Facebook groups. Each has its own process, phone number, and timeline. It's fragmented and exhausting.
ReportLost simplifies it. One report, one submission. We notify all the right Clayton authorities and services at once, then keep your report actively searching for a match throughout your chosen search period. No daily monitoring on your part, no calling back repeatedly to check. You file once, and the system works for you.
