Report your loss now
The sooner you submit a report, the sooner your item enters our active search. Every day counts when you've lost something valuable, and starting the process today means your report is working tonight. Once you've filed, you can step back. We'll monitor the channels and alert you if a match surfaces.
Report my lost item →Lake Oswego's downtown core, parks, and local transit routes see items left behind or misplaced every day. But finding help isn't straightforward when the Police Department, City services, local shops, and community groups each maintain separate channels. You end up juggling phone calls, emails, and social media searches instead of focusing on what matters.
ReportLost simplifies the whole process. One report, routed to every relevant local authority and community channel at once. Once submitted, your report works for you around the clock for up to a year, automatically comparing your description against newly found items and community posts. No more refreshing the same Facebook groups or calling back repeatedly. You report it once, and we keep searching.
