You file your report
Tell us what you lost, where, and when. We gather all the details needed to contact the right offices in Chelsea without you having to make multiple calls.
We route it to the right places
Your report goes directly to the Chelsea Police Department's lost & found desk, the MBTA if it's transit-related, shelters if it's a pet, and onto local social networks where people are already posting finds.

Report my lost item →Losing something in Chelsea can feel like navigating a maze. Whether it was left on a bus, dropped in a shop on Broadway, or mislaid at a local business, the item could end up in any number of different places, each with its own lost & found system. The Chelsea Police Department keeps items, the MBTA has its own recovery process, individual stores and restaurants handle their own, and community members post finds on social media. Making all those calls and checking all those channels takes time and energy you might not have.
ReportLost simplifies that. File one report with us, and we connect you to the Chelsea Police, the MBTA lost & found hotline, local animal shelters, and the active Facebook and Nextdoor communities where Chelsea residents are already looking and posting. More importantly, once your report is filed, you don't have to keep checking back every day. Your report stays active and continues to search for a match for up to a year, alerting you if something credible turns up, so you can focus on other things while we help bring your item home.
