Lost something in Denver? Report it once and we handle the rest.
One report gets routed to the Denver Police Department, RTD Transit, the Denver Animal Shelter, and all relevant local channels. Then we search the web continuously for your item so you don't have to.
What did you lose?
If there isn’t an adequate suggestion, select “Other – My item isn’t listed” and enter the item’s category. You can provide details later.
Publishing your report is free and your details stay private. The assisted search is a separate paid service, described in the Terms.

How ReportLost works in Denver
You submit one report
Tell us what you lost, where, and when. We gather the details we need to alert the right Denver agencies and services.
We route it to the right places
Your report goes to the Denver Police Department, RTD Customer Care, local animal services if applicable, and active lost item channels across Denver. You're covered without having to make multiple calls.
Automated monitoring finds matches for you
For months, we scan Facebook groups, Nextdoor, Craigslist, Marketplace, Reddit, and other public channels where Denver residents post found items. When a credible match appears, you get an alert instantly. No need to check these sites yourself every day.
Where lost items go in Denver
Here's what happens locally, and how ReportLost saves you time.
Denver Police Department
Lost items can be reported to the Denver Police via their online form or non-emergency line. Reports are filed and held at the relevant precinct, but you're responsible for following up. With ReportLost, we generate the exact information police need and let them know on your behalf.
RTD (Regional Transit District)
Lost something on an RTD bus or train? RTD holds items for 30 days. Call Customer Care or file a report online, but the process means separate contact and tracking. We know which RTD line and station to contact based on your details, and we follow up for you.
Denver International Airport (DEN)
If you lost something at DEN, the airport's lost and found desk is in Jeppesen Terminal Level 1 East. Items are held, but hours are limited and you must retrieve in person or coordinate by phone. ReportLost logs your loss and checks with DEN on your timeline.
University of Colorado Denver & Metro Area Campuses
Lost something at CU Denver or another local campus? Each has its own lost and found and security office, and calling the right desk is half the battle. We know which campus departments to contact and what details they'll need.
Lost Pets in Denver
A lost pet is a different kind of emergency. The Denver Animal Shelter holds unidentified pets for 5 days, and time matters. There's also the Humane Society of the South Platte Valley and community networks. Coordinating across all of them is critical. File a priority lost pet report to get your pet in front of shelters, vets, and thousands of local eyes immediately.

The sooner you report, the better
Items get found within the first week more often than not. Starting your ReportLost report right now means we can begin scanning and routing immediately. Once it's filed, the surveillance runs automatically in the background while you focus on the rest of your day.
Report my lost item →Losing something in Denver means contacting the police, checking RTD's lost and found, posting on Nextdoor or Facebook, and then refreshing all those channels for weeks. It's overwhelming, and items often slip through the cracks because the systems aren't connected. ReportLost simplifies this. One form, and we take it from there, routing your loss to all the places that matter and watching the web for you.
The difference is our continuous monitoring. Once you've reported, you can breathe. We're scanning marketplaces, social media, transit channels, and shelter databases throughout the Denver metro area for months. The moment your item surfaces online, you'll know about it. That peace of mind is worth the few minutes it takes to report.

What's the RTD lost and found holding period?

Does ReportLost replace calling the Denver Police or RTD?
ReportLost is an independent service that coordinates reporting on your behalf and monitors the web continuously. We notify the right agencies and channels so you don't have to call multiple places yourself. We're a bridge between you and local systems, not a replacement for them.
How does ReportLost know where to route my report?
You tell us the location and type of item you lost. Based on that, we route to the right police precinct, transit authority, airport, campus, or other facility. Our system knows Denver's geography and local holding policies, so the report goes to the right desk the first time.
