How it works
You report your loss
Fill out a simple form with details about what you lost: description, where and when, and how to contact you. We ask for the specifics that matter most in searches.
We connect you to the right places
Your report goes to Belmont Police, town services, and the MBTA if applicable. We tell you exactly which office covers your loss, provide their contact details, and guide you through next steps if you want to follow up yourself.
Your report stays active and searching
For 12 months, your description is automatically matched against items turned in locally and posted in community groups. You'll get an alert as soon as a credible match appears, so you don't have to check back every day.
Where lost items go in Belmont
Each service handles items differently. Here's what to know and where ReportLost can help.
Belmont Police Department
The Police Department at 460 Concord Ave is the main point of contact for most lost items found in town. Items are logged and held at the station. We identify the correct precinct and provide you with their direct line and hours so you can inquire or arrange pickup.
Town Offices & Services
Belmont Town Hall (455 Concord Avenue) oversees town services and venues. Items lost at public facilities or town events may be held here. We generate the exact department to contact and their phone number so you know who to call and what to ask for.
MBTA Transit (Bus & Subway)
If you lost an item on the bus or during your commute through the MBTA system, the transit authority holds items separately by route. We point you to the MBTA's lost and found phone line and explain how to describe your item so they can search their records.
Boston Logan Airport
Items lost at Boston Logan International Airport are held by the airport's Lost and Found office, which serves all four terminals. The process is free and straightforward. We provide the contact details and explain what information you'll need when you call.
Lost Pets
If you've lost a cat, dog, or other pet, contact Belmont Animal Control immediately at 617-993-2724 (24-hour line). They coordinate with local shelters and can help spread the word through local networks. File a priority lost pet report to get faster, specialized assistance.

Your report does the searching for you
Once you've filled out your report, our team routes it to the right Belmont services and keeps it active. You won't have to call around or refresh community pages every day—we notify you the moment a matching item turns up.
Report my lost item →Losing something in Belmont leaves you juggling calls to the Police Department, Town Hall, and transit services, each holding items separately and for different periods. It's easy to miss where your lost wallet, passport, or watch ends up, and harder still to keep searching across all these channels once weeks pass.
ReportLost simplifies that. One report reaches all the relevant services at once. We tell you which office holds items and for how long, guide you through the process if you need to claim something yourself, and keep your report active for a full year, automatically watching for matches so you can move on while the search continues.

Frequently asked questions
How long does the Police Department hold lost items?
The Belmont Police Department's retention period varies by item type. Contact them at 617-993-2501 (non-emergency) to ask about your specific item. Once an item is logged, they can tell you how long they'll keep it before disposal.
Can I file a report if I'm not sure exactly where I lost my item?
Yes. Even if you're unsure about the exact location, provide as much detail as you can: the general area (downtown, near the MBTA stop, at a specific store), the approximate time, and a complete description of the item. We'll route it to the services that cover that area.
What if I find my item after I've made a report?
Great news. Contact us to let us know, and we'll note your report as resolved. You can also cancel your report or ask for it to be taken offline if you'd prefer.
Are items at Belmont Town Offices held for a specific amount of time?
Retention periods depend on where the item was found and what type it is. Check with Town Offices at 617-993-2600 to ask about your specific case. We'll provide you with the right department to contact.
How does ReportLost's 12-month report work if the Police Department only holds items for 30 or 60 days?
Police and other services hold physical items for a limited time. Our report stays active longer because we're also monitoring community posts, local networks, and platforms where found items are shared. Even after an item leaves official custody, people often post about found items in local groups and social media. Your report continues to match against those posts.
Is ReportLost.org an official Belmont service?
No. ReportLost is an independent service that works alongside official channels like the Belmont Police Department, Town Offices, and the MBTA. We're not affiliated with any government agency, but we connect you to them and keep your report active longer than they hold items themselves.
