📝

You report your loss

Tell us what you lost, where, and when. We gather the details needed for Newark's police department and local transit systems in one go.

🚀

We connect it to the right places

Your report reaches Newark Police, AC Transit's lost and found, the TriCity Animal Shelter (if applicable), and gets posted to relevant community groups, so you're covered across all channels at once.

Your report keeps searching

For the full duration of your plan, your report automatically matches against new found items posted online and shared by local services. We alert you if a credible match appears, so your search continues even while you move on.

The Newark Police Department handles lost and found reports and holds items for a standard retention period. We identify which precinct covers your loss location and generate the exact details you'll need when you file. Contact them at the non-emergency number to check on an item or file a report directly.

Report my lost item →

Losing something in Newark means contacting the police department, checking AC Transit's lost and found, posting to Facebook groups, and monitoring local classifieds all separately. Each channel moves at its own pace, and if your item hasn't turned up in a few days, the trail grows cold quickly.

ReportLost simplifies this. One report reaches all the right Newark services at once, and stays active automatically, checking for matches continuously. Instead of refreshing multiple sites every day, you describe your loss once and let our system keep searching for you while you focus on what's next.

You're always welcome to file reports directly with the police or other agencies, and we recommend doing so for insurance and legal purposes if needed.
