How ReportLost Works in Kirkland
You describe your loss
Tell us what you lost, where, and when. We gather the details that matter to each agency in Kirkland.
We route to the right places
Your report goes straight to Kirkland Police's Property & Evidence unit, King County Animal Services if it's a pet, Community Transit if it's on a bus, and other relevant local channels—all at once.
We search for it continuously
Our automated system scans Kirkland community groups, Buy Nothing pages, Nextdoor, Facebook Marketplace, and local social media daily for months. You get an alert the moment a credible match appears, so you never have to manually check the same sites over and over.
Where to Report a Lost Item in Kirkland
These are the official channels. ReportLost files with them and monitors for you.
Kirkland Police Department
Kirkland Police handles lost property reports and holds items at their Property & Evidence unit. If you find an item with a Kirkland license tag or suspect foul play, they're your first contact. We tell you which department to reach and generate the information they'll need.
Kirkland City Hall & Services
City Hall can direct you to specific departments if your loss occurred at a city facility or park. We ensure your report reaches the right desk so you're not transferred multiple times.
Community Transit & Sound Transit
Lost something on a bus in Kirkland? Community Transit and Sound Transit each manage their own lost-and-found systems. Our team contacts them directly and describes your loss so they know exactly what to look for in their warehouses.
Seattle-Tacoma International Airport
If you left an item at SEA during travel to or from Kirkland, the airport's Lost & Found on the Baggage Claim Level holds it temporarily. We ensure your description reaches them and they retain it for the right amount of time.
Lost Pets in Kirkland
Stray animals in Kirkland are reported to and held by King County Animal Services. We get your pet's details to the right animal control office immediately, and we monitor PawBoost, Nextdoor pet alerts, and local Facebook groups to catch posts from people who've spotted your pet. If you've lost a pet in Kirkland, file a priority lost pet report with us right away.

The sooner you report, the better your chances
Items found in Kirkland are often held for a limited time before being discarded or donated. Once your loss is filed with the right agencies and our monitoring begins, you can focus on other things—we'll be watching for your item across the web.
Report my lost item →Losing something in Kirkland—whether at one of the downtown parks, on the waterfront, during a commute on Community Transit, or at home—puts you in touch with several separate agencies and platforms. Kirkland Police handles property reports, King County Animal Services manages stray pets, and transit has its own lost-and-found process. Most people end up calling around and checking Facebook groups repeatedly, hoping someone posts their item.
ReportLost simplifies this. One report reaches all the right channels at once. But the real difference is the waiting: instead of you refreshing lost-and-found pages and Kirkland community groups every day, our system does it for you. We monitor the web in the background, watching for your item across marketplaces, Nextdoor, Buy Nothing, and local social channels for months. The moment someone posts 'found' and it matches your loss, you'll know.
