Where to report in Rancho Cucamonga
Here's what happens behind the scenes when you file with ReportLost, and what you can do on your own if you prefer.
Rancho Cucamonga Police Department
The RCPD handles lost and found reports for items lost in public spaces and businesses across the city. You can call their non-emergency line or visit in person at Civic Center Drive. We file your report with them automatically and confirm receipt so you know it's in the system.
City Hall & Community Services
Rancho Cucamonga's City Hall coordinates lost and found inquiries across departments and can direct you to specific city facilities. We tell you which department handles your loss type and generate the exact details to include in your claim.
Omnitrans Bus Lost and Found
If you left something on an Omnitrans bus in Rancho Cucamonga, their lost and found office processes claims Monday through Friday. Items are typically held for a set period. We contact them on your behalf and track the status of your report with them.
Ontario International Airport
Ontario Airport (ONT), just 15 minutes away in Ontario, serves the Rancho Cucamonga area. Their Lost and Found office is located in Terminal 2 behind the Information Desk and holds items for an extended period. If your loss occurred at the airport, we file the report directly with their team and follow up on retrieval options.
Rancho Cucamonga Animal Center
The City's Animal Center receives lost pets, strays, and found animals daily. Call them immediately if you've lost a pet, and they'll check their current animals and add yours to their lost pet alerts. We notify the Animal Center of your missing pet and monitor their social channels and local alerts continuously to connect you with any matches. For a priority response, file a priority lost pet report.

Getting started is fast
A detailed report takes about three minutes to complete. Once submitted, you'll have confirmation that your information has been shared with the relevant local agencies and that automated monitoring has begun. From there, the process works quietly in the background.
Report my lost item →Losing something in Rancho Cucamonga means navigating separate systems: the Police Department handles lost property reports, the City's Animal Center covers pets, Omnitrans manages bus items, and Ontario International Airport (15 minutes away) has its own lost and found. Local Facebook groups and Reddit threads fill up daily with found items, but scanning them all takes hours you don't have.
ReportLost bridges that gap. One form, one submission, and we notify all the right channels at once. More importantly, we don't stop there, we keep watching the web for you. While you go about your day, our automated monitoring scans social media, community forums, and local networks continuously for the next six to twelve months, alerting you the moment a credible match appears. It's the shortcut that turns a stressful loss into a simple, managed process.
