How it works
You submit your loss
Tell us what you lost, where, and when. Include any identifying details that would help someone recognize it. The more specific, the faster we can work.
We route it to the right places
We file your report with the Arlington Police Department and other relevant local services. We also generate the exact details you'll need if you want to contact transit, the airport, or other venues directly.
Your report stays active and searching
For 12 months, your report keeps matching against items turned in to local services, posts in community groups, and other found reports. You'll get an alert if a credible match appears, so you don't have to monitor sites yourself every day.
Where lost items end up in Arlington
Local channels and what to do if you want to follow up yourself
Arlington Police Department
The police department holds lost and found items at their main station and welcomes walk-ins to check for property. They also accept reports by phone through the non-emergency line. ReportLost files your report with the police department so you don't have to make the call yourself.
MBTA Bus Transit
If you left something on an MBTA bus serving Arlington, each route has its own lost and found line. Call the number for your specific route to describe what you lost and ask if it's been turned in. We identify which MBTA routes serve your location and provide the exact contact numbers.
Boston Logan Airport
Arlington residents flying out of or arriving at Boston Logan should check the Lost and Found Office on the Arrivals level between Terminals C and E. Items left on aircraft or at security also have dedicated channels. We provide you with the phone numbers and location details for Logan's lost and found office.
Lost Pet
If your dog or cat is missing, call Arlington Animal Control right away. They coordinate with local shelters and maintain records of lost and found animals in the area. Time matters for lost pets, and Animal Control can alert other facilities and help identify your pet if it's been brought in. For a lost pet, file a priority lost pet report.
Shops, Restaurants, and Public Places
Items lost in stores, restaurants, libraries, or parks are typically held by the business or venue itself. Call ahead to describe what you've lost. If you're not sure which business to contact, your credit card or phone company's location history can help you pinpoint where you were.

Report your loss now
Filing a report takes just a few minutes. Once submitted, your details reach the right Arlington services and stay active in the search for a year.
Report my lost item →Arlington sits six miles northwest of Boston and shares transit and airport access with the broader region. A lost item in town might end up with the Arlington Police Department, the MBTA if you lost it on a bus, Boston Logan if it went missing at the airport, or local businesses and venues. Each system operates independently, and tracking down the right desk can take time.
ReportLost simplifies that. One report reaches the relevant Arlington services and continues searching for you automatically. If your watch, keys, wallet, or passport turns up, the match happens without you having to retrace your steps or refresh lost and found pages every morning.
