How ReportLost works in SeaTac
You submit your loss details
Tell us what you lost, where, and when. We pull together everything we need to alert the right offices across SeaTac and the airport.
We route to the right places
Your report goes to SeaTac Police, the Port of Seattle's Airport Lost & Found, Sound Transit, and local community channels, so you don't have to call each one yourself.
Your report keeps searching for you
We continue to match your loss against new found items and posts in local networks for your entire search period. You get an alert the moment a credible match shows up, so you can stop checking every day.
Report your loss to these channels
ReportLost connects you to all of them at once. Here's what each offers if you go solo.
SeaTac Police Department
The city police handle lost and found reports for items lost in SeaTac itself, outside the airport. Non-emergency dispatch is open 24/7 to take your report, and we generate the exact details they'll need to file and track your case.
Seattle-Tacoma Airport Lost & Found
If you lost an item at SEA airport, the Port of Seattle Police operates a dedicated lost and found office on the Baggage Claim Level across from Carousel 13. Items are held and searchable. We tell you exactly how to describe your loss so they can locate it faster.
Sound Transit & Metro Bus
Lost something on a Sound Transit or King County Metro bus in the SeaTac area? The transit system maintains a central lost and found office and accepts reports online or by phone. We point you to the right number and help you describe your item for their system.
City of SeaTac
SeaTac City Hall can point you toward local resources and may have additional lost and found contacts for community spaces and businesses. We handle the coordination so you don't have to.
Lost or Found Pet
If you've lost a dog, cat, or other animal in SeaTac or King County, contact Metro Animal Control immediately and check with King County Regional Animal Services. We also handle pet reports differently because time matters even more. File a priority lost pet report.
