How it works
You report your loss
Tell us what you lost, where, and when. We gather the details that matter and prepare them for the right channels.
We route it to the right places
Your report goes to Adams County Sheriff's Office, local business lost and founds, and relevant community groups all at once. No need to call around yourself.
Your report keeps searching
For 12 months, your report stays active and searches for matches as new found items come in. We alert you if there's a credible lead, so you can focus on your day.
Where to report a lost item in Derby
These are the official channels. ReportLost coordinates them for you.
Adams County Sheriff's Office
Report stolen or lost property directly to the sheriff's office. They maintain a record and can help coordinate with local police. We tell you which precinct covers your loss location and generate the exact information to include in your report.
City and County Services
Derby is an unincorporated community governed by Adams County. City offices and county departments may hold items found on county property or in public spaces. We point you to the right desk and help you phrase your inquiry so they understand what you're looking for.
Shops, restaurants, and local businesses
If you lost your item at a specific store, restaurant, or venue in Derby, call them first. Items are usually kept for 30 to 90 days before disposal. ReportLost helps you draft a clear description so staff know exactly what to look for in their lost and found.
Denver International Airport
If your loss happened at DEN while traveling through Denver, the airport's lost and found operates separately. Items are held for extended periods. File a claim online or visit the office on Level 1 East.
RTD (Regional Transportation District)
If you lost something on a bus or at an RTD station in the Denver metro area, RTD's lost and found handles inquiries. Items are retained for a set period. Report online or by phone and describe your item clearly.
Lost or found pet
Pets missing in the Derby area should be reported to Adams County Animal Control immediately. Check local shelters, vets, and community lost pet groups. The sooner you file, the sooner volunteers and shelter staff can help reunite you. File a priority lost pet report to boost visibility across Colorado networks.

Get ahead of the search
The first hours and days matter most when something goes missing. Filing a report early with accurate details gives the right people the right information from the start. Once your report is live, the work of connecting with local channels and keeping an eye out continues automatically—you can breathe easier knowing the search is active.
Report my lost item →Losing something in Derby means contacting multiple places: the sheriff's office, shops and restaurants where you've been, community groups online. Each channel has its own process, timing, and gaps. By the time you've called the third place, details blur together.
ReportLost simplifies that. One detailed report reaches Adams County authorities, local lost and found desks, and the neighbors and groups most likely to spot your item. And because your report stays active, you're not refreshing Facebook groups or checking Craigslist every evening. The search continues automatically for months while you move forward.
