How ReportLost Works in Centennial
You file your report
Tell us what you lost, where, and when. We'll help you describe it clearly and pinpoint the right location in Centennial.
We route to the right places
Your report goes directly to the Centennial Police Department, relevant city departments, and public transit lost and found (RTD). No back-and-forth calls.
Automated monitoring finds matches for you
Our system scans Centennial-area Facebook groups, Nextdoor, local marketplaces, and the web for 'found' posts that match your description. You get an alert the moment a credible match appears, so you can stop refreshing on your own.
Where Lost Items Go in Centennial
These are the places that hold or receive lost items in the area. We report to them on your behalf, but here's where to reach them directly if you prefer.
Centennial Police Department
Items found on city streets, in public spaces, or turned in by residents often end up at the police station. ReportLost notifies them with your full description and contact details so they can reach out immediately if someone brings in a match.
Centennial City Hall
City services, parks, and public facilities route lost items to City Hall's central office. We alert them with your report so staff can flag your item if it arrives and connect you right away.
RTD Lost and Found
Anything left on an RTD bus, at a transit stop, or in a station gets logged by RTD. We provide RTD with your description so staff can check their database and notify you if your item shows up.
Denver International Airport
If you lost something at DEN before traveling to or from Centennial, the airport's lost and found holds items by gate or terminal area. ReportLost can flag your loss if it involves airport travel, and you can also search DEN's system directly.
Lost Pet
If your cat, dog, or other pet is missing in Centennial, time is critical. Arapahoe County Animal Services maintains a database of found animals and posts alerts on 24 Pet Connect. Community groups on Facebook also share sightings. We recommend you file a priority lost pet report so you get specialized support and social amplification right away.

The sooner you report, the better your chances.
Every hour matters when something goes missing. The longer you wait to notify the right departments and community channels, the easier it is for a found item to be discarded or moved. A single report through ReportLost gets the ball rolling immediately across all the right places in Centennial, and activates our monitoring so matches come to you automatically.
Report my lost item →In Centennial, a lost wallet, phone, or bag can end up at the police station, City Hall, an RTD bus depot, or in the hands of a kind stranger posting on a local Facebook group. Without a single coordinated place to check, most people spin their wheels calling around or refreshing social media every few hours, hoping someone posts a photo of their missing item.
ReportLost consolidates that chaos. One submission reaches all the right departments and offices at once, and then our surveillance system keeps working for you, scanning public posts and listings across the web every day for months. You describe your loss once, and we do the heavy lifting of watching, matching, and alerting you so you can focus on your day.

Contact RTD Customer Care at 303-299-6000 (press 2 for Spanish, then Option 3 for lost and found) or report online at rtd-denver.com. We'll alert RTD as part of your report, but calling them directly can speed things up if your item is recent.
