Where Items Turn Up in Northglenn
Know where to report and how ReportLost bridges the gaps
Northglenn Police Department
The Northglenn Police holds found items and maintains a property database. Call their Property Evidence Technician at 303.450.8849 to check if your item has been turned in. We automatically notify them of your report and provide the exact details they need to log it properly.
RTD Lost & Found
If you lost something on RTD transit in the Denver metro area (including services through Northglenn), RTD's central lost & found is your repository. Call Customer Care at 303-299-6000 (Option 3 for lost & found) or report online. We'll alert RTD to monitor for your item across their fleet and facilities.
Denver International Airport
Traveling through DEN? The airport's lost & found (Level 1 East, Jeppesen Terminal, near doors 111-113) receives items from terminals and baggage areas. Hours are 8 a.m. to 7:30 p.m. weekdays, 8 a.m. to 6 p.m. weekends. We'll ensure your report reaches them if your loss happened at the airport.
Retail & Community Venues
Northglenn's shopping centers, restaurants, libraries, and the Community Center often hold lost items for a limited time (typically 30-60 days). Call directly if you know the business. ReportLost posts your report to local lost & found community groups, multiplying your chances someone spotted it and will connect with you.
Lost Pet
If a pet is missing, time matters. Contact the Denver Animal Shelter (720-913-1311) immediately to check their intake, and post in the Tri-County Colorado Lost and Found Pets group. Get your pet's details on PawBoost and contact local veterinary clinics and animal rescues. For dedicated support throughout your search, file a priority lost pet report.

The sooner you report, the better your odds
Items left unclaimed in Northglenn move through the system quickly. Filing your report now creates a record that stays active across multiple channels and keeps searching for months, even if you can't spend hours refreshing websites every day.
Report my lost item →Northglenn's spread-out neighborhoods, shopping areas, and transit connections mean a lost item can land in a dozen different hands. You might need to call the Northglenn Police Department's property technician, check RTD's lost & found, post in the Tri-County Facebook groups, and call local shops all separately. Each channel works independently, and items disappear quickly if no one's actively searching for them.
ReportLost simplifies the hunt. File one report and we notify the right local authorities and community networks on your behalf, then keep your report active and scanning for matches across platforms for months, so you can move forward while the search continues behind the scenes.
