The sooner you report, the better your chances.
Items move quickly. A lost wallet found on a bus gets turned in and held for a window of days. A lost pet found in a neighborhood gets posted to social media and shared among neighbors fast.

Once your report is live, you can breathe easy. The system is searching.
Report my lost item →In Newcastle, lost items can scatter across multiple agencies: the police department handles reports, King County Regional Animal Services manages stray pets, Community Transit holds items left on buses, and Seattle-Tacoma Airport processes luggage if you're traveling through. Local Facebook groups and Nextdoor fill gaps, but there's no single place where all those channels talk to each other. If you're searching for a wallet, phone, ring, or pet, you end up making the same calls and posts repeatedly.
ReportLost cuts through that fragmentation. You file once, we notify all the right local contacts, and your report stays live in the background, automatically watching for your item as new found posts go up across the community. Once you hit submit, you can stop searching. Your report works for you.
