How ReportLost Works
You tell us what you lost
Describe the item, where you left it, and when. We ask the right questions to capture details that matter: size, color, identifying marks, exact location.
We route your report to the right places
Your report reaches the Sammamish Police Department (206-296-3311), King County Regional Animal Services if it's a pet, Community Transit and Sound Transit lost and found if it's from a bus, and the relevant local channels automatically.
We search for matches while you move on
Our system scans social media, local Facebook groups, Nextdoor, community marketplaces, and online listings continuously for months. The moment we spot a credible match, you get an alert. No daily manual checking required.
Where to report your loss in Sammamish
Each of these channels can help, or let ReportLost coordinate the reporting for you.
Sammamish Police Department
Report lost property directly or file an online report for non-emergency incidents. The Sammamish Police Department partners with King County Sheriff's Office and can direct you to the appropriate lost and found if your item ended up at a local business or park.
City of Sammamish
City Hall can provide guidance on municipal property losses and connect you with relevant departments. We identify the right city contact based on where your item was lost.
Public Transit Lost and Found
Lost something on a Community Transit, Sound Transit, or other regional bus? Each transit agency maintains its own lost and found. We tell you which agency serves your route and what information to provide when you call.

One report, multiple agencies, continuous monitoring.
Getting your loss reported to the police, city services, transit, and community channels takes time and multiple calls. Let ReportLost handle the coordination and watch for matches across the web while you focus on other things.
Report my lost item →Sammamish residents know the sinking feeling: you realize you've left something behind at the park, on the bus, at a local business, or somewhere in town, and suddenly you're juggling calls to the police non-emergency line, transit customer service, animal control, and checking Facebook groups hourly. Each agency has its own process, its own hours, and the burden falls on you to follow up.
ReportLost simplifies that. One report gets your loss in front of all the right people and services at once, and then our automated monitoring takes over. We scan the web across social channels, community boards, and lost and found listings day and night for months, looking for posts that match your description. While you go about your day, we keep watch.
