How ReportLost Works
You Report Your Loss
Tell us what you lost, where, and when. We guide you through the details that matter most for recovery, so you don't have to guess what information to include.
We Route It to the Right Places
Your report goes straight to the Arvada Police Department, RTD transit lost and found (if applicable), Denver International Airport, and local community groups. You get one submission instead of calling five offices.
Automated Web Monitoring Finds Matches
We scan Facebook groups, Nextdoor, Reddit, classifieds, and lost-and-found marketplaces across the web for months, matching descriptions, location, and dates. You don't have to refresh pages every day, we alert you the moment a credible match appears.
Where to Report & Recover Lost Items in Arvada
Use these channels directly, or let ReportLost coordinate everything for you.
Arvada Police Department
The Arvada Police Department receives reports of lost property, but does not maintain an active lost and found service due to the volume of items turned in. If you've lost something and suspect it was turned in by someone, contact their Records and Evidence unit. We pinpoint the right precinct and department for your loss location, and provide the exact information they'll need to trace your item.
Non-Emergency: 303-980-7300|Records & Evidence: 720-898-6926
RTD (Regional Transit District)
If you left something on an RTD bus or at a transit center in the Arvada area, RTD's lost and found team can help track it down. They keep items for a period before they're cleared. We help you generate the route, date, and time details RTD needs to search their database.
Denver International Airport
Items lost at DEN are held at the lost and found near doors 111-113 on the Jeppesen Terminal Level 1 East. If your loss occurred at the airport, we'll send your information to DEN's team and help you file their online form to speed up the search.
DEN Lost and Found Hours: M-F 8 a.m.–7:30 p.m., Sat-Sun 8 a.m.–6 p.m.
City of Arvada
City Hall and various city departments may have information about lost items reported to municipal services. If your loss happened at a city facility or park, contact the main city line during business hours for direction to the right department.
Lost Pet
If you've lost a dog, cat, or other pet in Arvada, time matters. Local Facebook groups like Arvada Lost and Found Pets are monitored closely by residents and rescue volunteers who spot missing animals daily. We'll amplify your pet's information across these communities and scan for sightings continuously. For immediate help with your furry friend, file a priority lost pet report.

Start Your Report Today
The sooner you notify the right channels and start monitoring, the better your chances of recovery. Our system takes the coordination work off your shoulders, so you can act fast and then trust us to keep searching.
Report my lost item →Losing something in Arvada can feel scattered. The police department doesn't maintain a dedicated lost and found, transit items go to RTD, airport losses to Denver International, and community finds scatter across Facebook groups and Nextdoor. Most people end up calling multiple offices, posting in several groups, and checking back constantly, hoping someone will spot their item. ReportLost cuts through that chaos with one report that reaches all the right channels at once, and then keeps watching for you.
Once you file a report with us, your information goes where it needs to go: the Arvada Police Records and Evidence unit, RTD Customer Care, airport lost and found, and local social networks. But the real difference is our continuous automated monitoring. We scan the entire public web for weeks or months, looking for posts that match your lost item's description, location, and timeframe. The moment we find a credible match, you get alerted. You can focus on your day while our system works around the clock.
