Where items go missing in Mountain Lakes
And where to report them
Mountain Lakes Police Department
The police non-emergency line handles lost and found reports for items lost in public spaces or to theft. They maintain records and can advise on recovery steps. We generate the exact information to include and point you toward the right desk if you need to file in person.
Borough Hall
Mountain Lakes Borough Hall can direct you to the right department for items lost in municipal buildings or at borough events. They keep lists of unclaimed items and can connect you with specific offices if needed. We tell you which department covers your loss location and what information to have ready.
NJ Transit Lost & Found
If you left something on a bus or at a transit stop, NJ Transit's centralized system tracks recovered items across the network. Report online, by phone, or at a customer service office. We help you complete the exact description and confirm the right contact method for your situation.
Newark Airport (EWR)
For items lost at Newark Liberty International Airport, submit a claim through the EWR virtual lost and found office. The airport ships recovered items directly to you. We provide the contact details and help you document your loss for their system.
Lost Pet? Priority Reporting
If your dog, cat, or pet went missing in Mountain Lakes, the Montville Animal Shelter, local animal control, and community pet networks need to know immediately. Time is critical, and a coordinated alert across all channels dramatically improves recovery odds. File a priority lost pet report.
