Report my lost item →Losing something in Belmont can mean navigating separate lost and found systems across the police department, city services, transit providers, and scattered community posts. Each place operates independently, and items can slip through the cracks while you're left contacting them repeatedly.
ReportLost eliminates that friction. A single report reaches the Belmont Police Department, San Mateo County Animal Control, local transit lost and founds, and the community groups where residents post discoveries. Better yet, your report stays active for months, automatically hunting for matches as new items surface, so you can focus on other things while the search continues in the background.
