The sooner you file, the sooner our system can work for you. Once submitted, you can step back and let your report stay active while we keep matching it against new found items and community updates.
Report my lost item →Mount Prospect residents lose things everywhere: keys disappear in coffee shops downtown, phones slip out at the park, wallets get left on the Pace bus. The problem is that each place has a separate lost and found, each with its own phone number, hours, and procedures. Police handle some items, transit companies handle others, and local Facebook groups spread the word independently. It's exhausting to chase them all down.
ReportLost simplifies that chaos. File one report and we immediately alert the Mount Prospect Police Department, the village's lost and found systems, Pace transit, and the community groups where residents actually post found items. Better still, your report stays active for as long as you choose (12 months), so it continues matching your description against new found items and community posts without you having to revisit each channel every day.
