How ReportLost works in Sioux Falls
You report your lost item
Tell us what you lost, where, and when. We gather all the details needed to route your report to the right offices and search channels.
We route to the right places
Your report goes to the Sioux Falls Police Department, relevant transit systems, airport lost & found if applicable, and active community groups where locals share found items.
Automated monitoring finds matches for you
For 12 months, we scan Facebook groups, Nextdoor, local marketplaces, and community posts for items matching your description, location, and timeline. You get alerts as soon as a credible match appears, so you don't have to check every day.
Where to report lost items in Sioux Falls
These are the main channels. ReportLost handles the coordination and ongoing search for you.
Sioux Falls Police Department
The primary place to file a lost & found report. They maintain records of items turned in and can note your loss in their system. We route your report directly to them and provide you with the exact information needed for their intake process.
Sioux Area Metro (SAM Transit)
If you lost something on a bus, SAM Transit maintains a lost & found. Items are checked in at their dispatch office. We identify which transit lines cover your route and ensure your report reaches the right dispatch desk.
Sioux Falls Regional Airport (FSD)
Traveling through FSD? Lost items in the terminal are held by airport lost & found. Contact them directly if your item was left in a gate area or bathroom, or we can flag it in your report for automated airport monitoring.
Lost pets
If you're missing a cat, dog, or other animal, the Sioux Falls Area Humane Society and Sioux Falls Animal Control are your first stops. Call them immediately, and then file a priority lost pet report with us for continuous social monitoring and community alerts.
City of Sioux Falls
For items lost in municipal buildings or public spaces managed by the city, you can contact City Hall. We route your report with all relevant location and description details so staff know exactly what to look for.
⚠️ Spotted incorrect or outdated information? Let us know so we can review it.
The sooner you report, the better your chances
Early reports give the system time to flag your item across all channels before it gets misplaced or sold. Once you submit, you can rest easy, knowing our automated search is working for you.
Report my lost item →Losing something in Sioux Falls means navigating separate systems: the police department, transit lost & found, airport services if you were traveling, animal control if it's a pet, and scattered community posts across Facebook and Nextdoor. Tracking down the right office takes time, and many people miss potential matches because they can't monitor every channel constantly.
ReportLost simplifies this. A single report triggers a coordinated search across all the places that matter in Sioux Falls, and our system watches the web for you around the clock. Once you report, your job is done, the automated monitoring takes over, and we notify you the moment something that matches your item surfaces.
