Getting Your Report Out Faster
The sooner you file, the sooner automated monitoring kicks in. Once your report is submitted, we handle coordination with the police department, transit, airport, and local social channels. You can move forward knowing the system is working around the clock.
Report my lost item →Green Bay sees items left behind every day, on Metro Transit buses, in shops and restaurants along Main Street and downtown, at the airport, and around the neighborhoods where residents gather. Each place has its own lost and found system, and reaching them all separately takes time, repeated calls, and weeks of self-monitoring web pages and social posts.
ReportLost simplifies that. One submission reaches the right desks at the police department, sheriff's office, and transit authority in Green Bay, gets posted to local community groups, and triggers automated monitoring of the entire public web. You report once, stay informed automatically, and the community's resources work for you in the background.
