How it works
You report your loss
Tell us what you lost, when, and where in Dardenne Prairie. We gather the details we need to alert the right people.
We route it to the right places
Your report goes to St. Charles County Police, City Hall, animal control if it's a pet, and key community channels. You don't have to call around.
Your report keeps searching for you
For your entire search period, your report automatically matches against new found items, lost pet posts, and local activity. We alert you instantly if something credible surfaces.
What to do after you've reported with us
These are the official channels where your item might turn up. ReportLost alerts them for you, but here's where you can follow up or search yourself:
St. Charles County Police
If you lost something in a public space or on county property, St. Charles County Police may have it in their lost and found. We identify which station covers your loss location and send them your report. You can also call them directly at (636) 949-3000 during business hours (Monday–Friday, 8 a.m.–5 p.m.) or text 233733.
Dardenne Prairie City Hall
Lost items found in city parks, municipal buildings, or public spaces may end up at City Hall. We make sure they know what you're looking for. Stop by during business hours (Monday–Friday, 8 a.m.–4:30 p.m.) at 2032 Hanley Road, or call (636) 561-1718 to ask if something matching your description has been turned in.
Lost pet? Take priority action
If your pet is missing, time matters more than anything. St. Charles County Animal Services keeps records of found pets and can help you search. Call (636) 949-7387 or visit during business hours (Monday, Tuesday, Thursday, Friday 10 a.m. onwards). Beyond official channels, community posts get results fast. File a priority lost pet report with us to maximize your reach.
Shops, restaurants, and public spaces
Wallets, rings, phones, and bags are often turned in at the place where they were lost. If you remember where you think you lost your item, call that business directly. Many keep items in a back office for 30 days or more, so even if it's been a week, it's worth checking.
⚠️ Spotted incorrect or outdated information? Let us know so we can review it.
Getting ahead of the search
The sooner you report, the sooner we can start looking. Once your report is filed, the hard part is done. We handle the notifications and the ongoing search, and you hear back from us the moment something matches.
Report my lost item →Losing something valuable or irreplaceable in Dardenne Prairie can feel isolating, especially when you don't know whether to call the police first, check with City Hall, contact animal control, or post in a dozen different Facebook groups. Each service keeps its own records, and nothing talks to everything else, so your missing item can slip through the cracks.
ReportLost bridges that gap. One report covers all the official channels and community spaces that matter in St. Charles County. Better yet, your report doesn't stop searching after the first day. It stays active and continues matching your description against new found items and local posts for as long as you need, so you can stop refreshing the internet every morning and let our system work for you.
Where people lose things in Dardenne Prairie
Most losses happen in and around these neighborhoods and zones:
Bainbridge Subdivision
A residential pocket where pets and personal items go missing most often. Easy to lose something while walking, and easy for pets to slip away from their familiar area.
Hanley Road & City Center
The heart of Dardenne Prairie, home to City Hall and local businesses. Wallets, keys, and glasses are frequently left behind in shops and at municipal offices.
Ogden Road Bus Stop & Routes
Public transit hubs are classic loss hotspots. Phones, bags, and wallets left on buses or at shelters turn up in lost and found offices, but only if someone reports them.
St. Charles County Parks
Open green spaces are places where rings, bracelets, and other items slip off during activity. City Hall can help connect you with parks-specific lost and found.
Nearby O'Fallon & St. Peters
If your loss happened just outside Dardenne Prairie, you may need to loop in O'Fallon or St. Peters police. We can route reports across county lines.
Community channels that help
Lost and found items are shared constantly on these platforms. ReportLost alerts the right groups for you:
Facebook group where pet owners post sightings and recoveries across the county
Regional Facebook community dedicated to reuniting lost and found pets with their owners

Questions about losing something here
How long do St. Charles County Police and City Hall keep lost items?
Most police departments and municipal offices hold lost items for 30 to 90 days before disposal. City Hall keeps some items for extended periods, especially if they're valuable. Once you report with ReportLost, we'll follow up on your behalf, but it's smart to call City Hall at (636) 561-1718 directly if your loss is recent.
What if I lost something on a bus or at a bus stop?
Items left on the Ogden Road bus route or other Dardenne Prairie transit stops are sometimes collected and held at City Hall. Call City Hall at (636) 561-1718 to ask about bus-related lost and found, or contact the county transit service. ReportLost will make sure the right people know.
My pet is missing. What's the fastest way to search?
Call St. Charles County Animal Services immediately at (636) 949-7387. Also post in the Lost/Found/Sightings of Missing Pets in St. Charles County Facebook group and STL MO Lost Found Paws. File a lost pet report with ReportLost to amplify your reach across multiple channels at once.
Do I need to file a police report to use ReportLost?
No. ReportLost works independently. We file the report and alert police and other services on your behalf, but if you prefer to file directly, you can always call St. Charles County Police at (636) 949-3000 (Monday–Friday, 8 a.m.–5 p.m.) or text 233733.
How does ReportLost keep my report active for 12 months?
Your report description stays in our system and is continuously matched against new found items posted by individuals, shelters, police, and community members. If a credible match surfaces, we notify you immediately. You don't have to check back yourself every day.
Is ReportLost.org official or connected to the police?
ReportLost is an independent service. We're not part of St. Charles County Police or Dardenne Prairie City government, but we work with them. Think of us as a coordinator that simplifies the process and keeps your report active longer than you could on your own. We're not a replacement for police or official channels, but a way to make sure your loss gets to the right people and stays in the search.
