Lost something in Fort Collins? Here is where to report it.
One report triggers alerts across Fort Collins Police, CSU Campus Lost & Found, Larimer County Sheriff, and active local community channels. We then monitor the entire web for matches, so you don't have to refresh Facebook and Nextdoor every day.

How ReportLost works in Fort Collins
You describe your lost item
Tell us what you lost, where you last had it, and when. We'll ask for details that matter most for recovery, whether it's a wallet near Old Town, keys at a campus building, or a piece of jewelry lost downtown.
We route your report to the right places
Your report goes directly to Fort Collins Police Department, CSU Police if it involves campus, Larimer County Sheriff if needed, and the right lost & found desks at local businesses. We handle the legwork of knowing who covers what area.
We scan the web continuously for your item
While you go about your day, our system searches Facebook groups, Nextdoor, local marketplace listings, and community posts repeatedly over months. The moment a credible match appears, you get alerted. No more checking 10 different pages yourself.
Where to report a lost item in Fort Collins
Each office below accepts reports, but ReportLost files and monitors them all simultaneously.
Fort Collins Police Department
The main office for non-emergency lost property reports in the city. Call their non-emergency line or visit in person to file a report. We contact them directly and provide the exact information they need to process your case.
Non-emergency line: 970-419-3273|Visit fortcollins.gov for hours
CSU Police Lost & Found
If your item went missing on Colorado State University's campus or nearby student areas, CSU Police operates their own lost and found at Green Hall. We flag CSU-relevant reports so they receive your details immediately.
CSU Campus Lost & Found: (970) 491-6444|police.colostate.edu/lost-found
Larimer County Sheriff's Office
For losses in unincorporated areas around Fort Collins or if your item involves an incident outside city limits, the Sheriff's office handles the report. We determine jurisdiction and ensure the right county office receives your case.
Local businesses & public venues
Old Town shops, The Foothills Mall, restaurants, libraries, and recreation centers often hold lost items in their own lost and found. We help you identify which business your loss occurred at and provide the contact details you'll need. We also monitor their social channels for 'found item' posts.
Lost a pet?
If your companion animal is missing, the approach is different and more time-sensitive. The Northern Colorado Humane Society and local animal rescues are your first contacts, plus community pet alert networks. We have a dedicated process built for pets that coordinates with shelters and search groups. File a priority lost pet report instead.

The faster you report, the better
Every hour counts when an item is lost. The sooner your report enters the system, the sooner our monitoring begins and the more likely someone who found your item will cross our alerts. Once you've filed with ReportLost, you've done the hard part, and the search network takes over from there.
Report my lost item →Fort Collins spreads across multiple jurisdictions: the city police handle most areas, CSU Police manage campus and the surrounding student neighborhoods, and Larimer County Sheriff covers unincorporated zones. When you lose something, figuring out which office to call, what to include in your report, and whether anyone's found it often means piecing together scattered lost and found pages and hoping someone posts about it. ReportLost simplifies that chaos by filing your report once and routing it to every relevant office and channel at the same time.
More importantly, we don't stop at the initial report. We monitor Fort Collins' Facebook groups, Nextdoor, local Buy/Sell/Trade pages, and other community platforms 24/7, scanning for posts about found items that match your description. You report, and then our system works in the background for months, so you're not the one spending your evenings scrolling through dozens of local pages hoping someone recognized your lost item. Once the report is submitted, you can take a breath and let the network do the heavy lifting.

Frequently asked questions about lost items in Fort Collins
How long do Fort Collins Police and CSU Police keep lost items?
Fort Collins Police typically hold items for 30 to 90 days depending on the item's nature and value. CSU Police maintains a similar timeline but may release items sooner if space is needed. We advise claiming items as soon as you're notified of a match, as policies can vary. Check with the specific office holding your item for their exact retention period.
What if my item was lost at a business or mall?
Each business maintains its own lost and found, usually at the customer service desk or front office. We help you identify which location has jurisdiction and provide their contact info. After you report through ReportLost, we also scan those locations' social pages and community posts for found item announcements.
Can I file a report online with Fort Collins Police?
Fort Collins Police accepts online reports for non-emergency matters through their website. However, calling the non-emergency line at 970-419-3273 (Monday to Friday, 8 a.m. To 5 p.m.) often gives you real-time guidance on how to report your loss. ReportLost handles the filing for you and routes it to the right desk.
How often does ReportLost scan for matches?
Our system runs continuous searches across Facebook groups, Nextdoor, marketplace listings, and other public community channels multiple times daily. If a matching 'found item' post appears, you'll receive an alert within hours. We continue scanning for 12 months after your initial report.
What if my lost item is on CSU campus?
CSU Police maintains a dedicated lost and found at Green Hall. Call them at (970) 491-6444 or visit their office to report or claim items. If you report through ReportLost, we ensure CSU Police receives your report directly and monitor student Facebook groups and Nextdoor pages where campus-related lost items are often posted.
