We notify the right places

Where to Report Your Loss in Rialto
Here's how the system works, and what ReportLost does to save you time.
Rialto Police Department
The Rialto Police Department handles lost and found reports for items lost on public property or in connection with an incident. You can call the non-emergency line, visit in person, or ask about filing a report online. We make sure your report reaches the right desk and confirm the correct precinct and details.
City of Rialto
Rialto City Hall can assist with items lost in municipal buildings or provide guidance on local lost and found protocols. Contact the main number or visit during business hours. We help you identify whether your loss should be reported to City Hall or another department.
Public Transit
If you lost something on a bus or at a transit station, Riverside Transit Authority (RTA) operates in the region and maintains a lost and found office. Items are held for a set period. We connect you with the correct transit authority and provide them with your report details.
Ontario International Airport
The nearest major airport is Ontario International Airport, about 20 miles from Rialto. If you lost an item at the airport, their dedicated lost and found office can assist. We provide you with their direct contact information and the proper reporting procedure.
Lost Pet
If you've lost a pet in Rialto, time is critical. San Bernardino County Animal Care and Rialto-area community groups on Facebook mobilize quickly to help reunite animals with their families. We help you post alerts and contact the right shelter immediately. File a priority lost pet report.

Ready to get your report in motion?
The sooner you file, the sooner our team starts monitoring and routing to local services. Most cases see activity within the first few hours of posting.
Report my lost item →Losing something in Rialto can feel overwhelming, especially when you're not sure which office to contact or how often to check online groups. The police handle certain items, the city may maintain records, transit systems have their own lost and found processes, and community groups post findings constantly. Without a central point, you can spend hours on the phone and refreshing screens with no guarantee of success.
ReportLost simplifies that mess. One form, one submission, and we handle routing to every relevant Rialto authority and channel. Then our monitoring team watches the web continuously, cross-referencing descriptions, dates, and locations across dozens of local and regional sources for months. You report once and let us search for you.
