How it works
You tell us what you lost
Describe your wallet, ring, phone, or pet in a few details. We gather exactly what the right offices need to hear.
We notify the right channels
Your report reaches Southampton Town Police, the local animal shelter, Flanders community groups, and broader social networks in your area. No need to call each one yourself.
Your report keeps searching for a match
For your entire search period, we continuously match new found posts, shelter intake lists, and local announcements against your description. You'll get an alert if a credible match appears, so you don't have to check every day.
Where to report a loss in Flanders
Know your options. We'll handle routing your report to the right one.
Southampton Town Police
File a lost property report with the department that covers Flanders. Police can issue an official report and store information for items turned in to their lost and found. We connect you to the right precinct and help you draft the details they need to hear.
Southampton Animal Shelter (SASF)
If you've lost a dog, cat, or other pet, contact the Southampton Animal Shelter immediately. They receive reports of stray animals and can check whether your pet has been brought in. We help ensure your lost pet report reaches them and stays in their system.
Local community and social networks
Flanders residents actively share lost and found posts on Facebook groups and Nextdoor. We broadcast your report across these channels so neighbors see it quickly. Many lost items and pets are recovered through community tips.
If you lost something on a bus
Lost an item on a Suffolk County transit bus? Call the driver's dispatch or contact the transit authority directly. We can guide you to the right phone number and what info to provide.
If you lost something at a regional airport
Lost something at LaGuardia, JFK, or another airport serving the New York area? Each airport runs its own lost and found office. We point you to the right airport's claim process.
⚠️ Spotted incorrect or outdated information? Let us know so we can review it.
The sooner you report, the better your chances.
The first few hours matter. Once your report is filed and routed to the right places, you've done the hard part. We take it from there, keeping your case active in the background while you explore other options.
Report my lost item →Losing something valuable in Flanders, whether it's a personal item at the beach, in a local shop, or a beloved pet, means contacting multiple places: the police non-emergency line, the animal shelter, Facebook groups, Nextdoor, and more. Each organization runs its own system, and nothing ties them together. By the time you've called everyone, hours or even days have passed.
ReportLost simplifies that chaos. One report, filed once, reaches all the right places at once and stays active for months. We handle notifying Southampton Town Police, the local animal shelter, and community channels, then continue monitoring for matches automatically so you can focus on other leads or simply have peace of mind knowing your case is still actively being searched.

Frequently asked questions
How long will Southampton Police keep my lost item if someone turns it in?
Police lost and found departments typically hold items for 30 to 90 days before disposal. File your report promptly so they have your description on file, and follow up every 2 to 3 weeks to check status. We help you track this.
What if my pet was found and brought to the animal shelter? How do I know?
Call the Southampton Animal Shelter at 631-728-7387 and ask if any pets matching your description have arrived. You can also visit in person with a photo. Check their social media daily for posted strays. Our report ensures your pet's details are in their system.
Do I need to file a police report to use ReportLost?
No. We file your report independently and route it to the police, animal shelter, and community channels in one go. You don't need to call 911 or visit the station yourself unless you prefer to file an official police report as well (which is useful for some insurance claims).
How often are lost and found items posted on Flanders Facebook groups and Nextdoor?
Multiple times a day, especially for pets and wallets. Neighbors are active in sharing sightings. Our service broadcasts your report to these groups so you reach that audience instantly, and we continue watching for new found posts that match your description.
What happens after 12 months? Does my report expire?
Yes, at the end of your chosen search period (12 months), your report stops being actively monitored for new matches. Most items and pets are recovered within the first few weeks or months. You can renew your report if you wish to continue searching.
Is ReportLost official or does it replace calling the police?
ReportLost is an independent service, not affiliated with any government agency. We complement official channels, not replace them. We route your report to the Southampton Police, animal shelter, and community networks, but we don't have access to their internal systems. Think of us as your coordinator, making sure your case reaches everyone who can help.
