Frequently asked questions

How long will the Monroe County Sheriff's Office hold a found item?

The Sheriff's Office typically holds found property for 30 to 90 days, depending on the item type and value. This is why filing your report early matters: the sooner you're in their system, the higher the chance a match is recorded while the item is still in custody.

What if I lost my item at the airport?

Call the airport lost and found at 305-809-5200 immediately. The Monroe County Sheriff's Office manages the airport's system. When you file a report with ReportLost, we ensure your item is flagged in both the airport database and the general Sheriff's system.

Can I report a lost pet with ReportLost?

Yes, and we recommend it. Contact the Marathon Animal Shelter right away at 305-743-4800, then file a priority lost pet report with us to activate emergency protocols and connect with local animal control, shelters, and pet-focused community networks across the Keys.

How do I search for a found item myself while my report is active?

Check the Monroe County Sheriff's Office lost property database online or call 305-289-2430. Follow the Facebook groups listed above, especially Lost and Found Pets Florida Keys and local Nextdoor boards. Your ReportLost report continues running in the background, so you don't have to do this daily.

What if my item turns up on a marketplace or a Facebook post?

You'll receive an alert as soon as our system finds a credible match based on your description. You can then contact the seller or poster directly. Our team can also help you verify the match before you commit to recovering it.

Is ReportLost.org an official government agency?

No, ReportLost is an independent service. We're not part of the Monroe County Sheriff's Office or the City of Marathon. We help you file reports more efficiently and keep your search active longer, but we work alongside official channels, not instead of them.
