How ReportLost works
You report your loss
Tell us what you lost, where, and when. We gather the details that matter most to police and local services.
We route it to the right places
Your report goes directly to Greenwich Police, relevant Town departments, local lost pet groups, and community networks in Cos Cob. No runaround, no guessing which office handles what.
Your report keeps searching for you
While you move on, your report stays active. We cross-reference new found postings, marketplace listings, and community alerts with your description. When a credible match appears, you get an alert. Six to twelve months of automatic matching so you're not refreshing lost pet groups or police sites daily.
Where to report lost items in Cos Cob
Official channels you can contact directly, plus how ReportLost connects them for you.
Greenwich Police Department
Report lost items and property crimes to the police non-emergency line. They maintain records and can advise on next steps based on where your item was lost. ReportLost tells you the exact precinct and info to include, so your report is routed correctly the first time.
Greenwich Town Hall
Town departments coordinate with lost and found services for items turned in at public facilities. Reaching the right desk can take time if you're unsure which department handles your situation. ReportLost ensures your lost item report reaches the correct Town contact and stays in their system.
CTtransit Lost & Found
Items left on buses are held at the CTtransit Lost & Found office, open weekdays by appointment. They only take calls during limited windows, and you need to know exactly which route and date. ReportLost generates the specific details transit needs and flags your loss so it stays searchable across their system.
Lost Pets & Animal Control
Missing a dog, cat, or other pet? Report immediately to Greenwich Animal Control and post in local pet networks. Greenwich Animal Control responds to stray animals and maintains adoption records. The faster you get your pet's description circulating, the better. file a priority lost pet report with ReportLost to alert multiple pet networks and Animal Control at once.
Bradley International Airport
If you lost something at Bradley (about 40 minutes north), items are split between airport Lost & Found and Connecticut State Police depending on location. You'll need to call the right number for the right department. ReportLost helps you know who holds what and handles the follow-up.
⚠️ Spotted incorrect or outdated information? Let us know so we can review it.
Report now, let it search for you
The sooner you file, the better the chances your item circulates through official and community networks. Once your report is live, ReportLost handles the ongoing search. You can step back and we'll reach out the moment a credible match is found.
Report my lost item →Losing a ring, purse, phone, or beloved pet in Cos Cob can feel scattered, especially when local services don't talk to each other. The Greenwich Police handle reports, Town Hall has its own processes, lost pet networks rely on Facebook volunteers, and transit services keep separate logs. Most people end up calling multiple offices, reposting on multiple groups, and checking back constantly to see if anything turns up.
ReportLost simplifies that. One form tells Greenwich Police, Animal Control, and community channels at once. Better yet, your report doesn't expire after a day or a week. It stays active and keeps searching through matched postings for your entire search period, alerting you if a real lead emerges. You file once, then breathe; the network does the rest.
