Contact MCTS Lost & Found at 414-937-3206 between 8 AM and 4:30 PM, Monday through Friday. Have your bus route and the approximate time ready. ReportLost ensures your report reaches transit services automatically, so they can flag your item if it comes in.
Can I file a report for an item lost at Mitchell Airport?

How does ReportLost keep my report searching if I don't do anything?
Once your report is filed, we automatically cross-check new lost and found postings, community marketplace listings, Facebook group posts, and local found-item announcements against your item description. If we spot a credible match, you get an alert. No manual checking required on your part, and the search continues for the full duration of your plan, typically 6 to 12 months.
What's the difference between filing with ReportLost and calling the police myself?
ReportLost is faster and more thorough. We file your report with the Greenfield Police Department and simultaneously route it to city departments, transit services, and local community channels. We also add the automated continuous search component, which most individual police reports don't include. Think of it as doing the legwork once so you don't have to chase multiple agencies yourself.
Is ReportLost.org official or does it replace calling the police?
ReportLost is an independent service, not part of any government agency. We work alongside the Greenfield Police Department and local services, not in place of them. Your report is filed with the appropriate authorities through us, so you're covered both ways. We're here to make the process less frustrating and add continuous background searching that official lost and found offices typically don't offer on their own.
