Here's where to report and what ReportLost does for you.
Monrovia Police Department
The Monrovia Police handles property found at crime scenes and accidents, and also operates the city's lost and found for items turned in by residents and businesses. You can report in person or call the non-emergency line. We automatically notify the right department and provide your case details.

City Hall & City Services
Monrovia City Hall handles lost property reports related to city services and public spaces, and can direct you to the right department depending on where you lost your item. We generate the exact information you need to include when you call or visit.
Public Transit
If you lost an item on GoMonrovia or regional transit (Foothill Transit, Riverside Transit), separate lost and found systems handle each service. We tell you which carrier operates your route and what information they need.
Lost Pet
Monrovia's animal control partners with Pasadena Humane for lost and found pets. Pasadena Humane serves Monrovia daily, and community groups like 'Lost and Found Pets of Arcadia-Sierra Madre-Monrovia' on Facebook are active for quick reunions. We connect you immediately and help you post across all channels. If you've lost a cat or dog, file a priority lost pet report.

Getting ahead matters.
The sooner you report a loss, the better your chances of recovery. Once your report is in our system, the searching happens for you. Over the next 12 months, your item description stays active and matches against new found postings automatically.
Report my lost item →Losing something in Monrovia means dealing with separate systems, scattered phone numbers, and checking multiple Facebook groups every day hoping someone found your item. Between the police property room, animal shelters, transit services, and community posts, it's easy to miss the right channel or fall through the cracks.
ReportLost simplifies that. One report reaches the Monrovia Police Department, Pasadena Humane, local transit, and active community networks all at once. And because your report stays active and searchable for months, you're not starting from scratch each time you check a new source. Our system keeps matching your description against incoming found items and alerts so the legwork continues without you.

Can I report a loss that happened a few days or weeks ago?
Yes. While reporting soon improves chances, we can file reports for older losses as well. Your report stays active for 12 months, so items found later can still match. Check with the relevant venue or police to see if your item may still be held.

Is ReportLost.org official? Does it replace calling the police?
ReportLost is an independent service, not a government agency. We don't replace the police or other authorities. We're a platform that consolidates your report and sends it to the right places so you don't have to call each one separately. You can always report directly to police or a lost and found yourself, but using ReportLost saves time and keeps your report actively searching.
