How ReportLost works in Longmont
You file one report
Tell us what you lost, where, and when. We collect all the details needed for police and local services in one place, so you don't have to repeat yourself across multiple channels.
We route it to the right places
Your report goes directly to Longmont Police Property & Evidence, the city's lost & found listings system, and relevant local businesses or services. We handle the coordination; you hear back from us with confirmation.
Automated monitoring finds matches for you
For months after your report, we scan Facebook groups, Longmont community boards, RTD channels, Nextdoor, and online marketplaces for posts matching your item. The moment a credible match appears, you get an alertâno need to refresh pages or check groups yourself every day.

The city's main repository for lost items turned in to police. Items are held at the Property and Evidence office, which answers questions about what's been brought in and coordinates pickup. We automatically flag your item with them so they watch for it.
City of Longmont Lost & Found Listings
The city maintains a published list of items currently in custody. Check the online listings, or contact the main information line. We ensure your lost item is added to these lists and monitor them continuously for matches reported by finders.
RTD (Regional Transit District)

Longmont Humane Society
If you've lost a dog, cat, or other pet in Longmont, the Humane Society is the first stop. They operate a shelter, lost & found service, and post animals online. Report immediately so they can watch for your companion and alert you if someone brings them in. File a priority lost pet report with ReportLost to also trigger alerts across local shelters and pet networks.
Local shops & public spaces
Lost something at a restaurant, coffee shop, mall, or community venue in Longmont? Businesses often hold found items in their own lost & found for a limited time before discarding them. We contact relevant businesses near where you lost your item and ask them to keep an eye out, plus track online posts where finders describe what they've found.

The sooner you report, the better your chances
The first few hours and days after a loss are criticalâitems move fast, and memory fades. Getting your report into the system immediately means Longmont Police, the city, RTD, and our monitoring all start working for you right away. Once it's filed, you can exhale. We take it from there.
Report my lost item âLongmont residents juggle several channels when something goes missing. The police property room, the city's lost & found listings, RTD if it happened on a bus, Longmont Humane Society if it's a pet, plus scattered Facebook groups and Nextdoor posts from neighbors. Without a central hub, items slip through the cracks, and you end up making the same phone calls and searches repeatedly.
ReportLost streamlines the whole process. File once, and we notify the right local authorities and services, then keep watching the webâmarketplaces, community boards, and social channelsâevery day for weeks or months until your item surfaces. You focus on your day; we focus on bringing it back to you.
