How ReportLost Works
You report the loss
Tell us what you lost, where, and when. We confirm the right jurisdiction and gather the details needed for each recovery channel.
We route it to the right places
Your report goes to the Cupertino Police Department, City Hall lost & found, SamTrans (if applicable), and relevant local community networks all at once.
Automated monitoring finds matches for you
For months, we scan the web automatically, checking community posts, marketplaces, local social channels, and transit systems for credible matches. You get alerted instantly if something turns up.
Where to Report in Cupertino
Each channel below can help. ReportLost notifies them on your behalf and monitors their activity for you.
Cupertino Police Department
The West Valley Sheriff's Division serves Cupertino. You can file a report in person or by phone for lost property. We tell you which precinct covers your loss location and what details to have ready.
City Hall Lost & Found
Items turned in to City Hall are stored at the front desk in the lobby. If your loss occurred at a city facility or park, this is often where items end up. We generate the specific contact details and location info you'll need.
Transit Services
If lost on a bus, SamTrans and other local transit operators maintain lost & found offices. We point you to the right transit authority based on your route and ensure your description reaches their recovery team.
San José Mineta International Airport
Traveling through SJC? The airport lost & found office processes claims for items left in terminals, gates, or vehicles. We help you reach them with the right information.
Lost Pet Services
If your pet is missing, report it immediately to Santa Clara County Animal Services and local shelters. They maintain searchable registries and coordinate with nearby facilities. Then file a priority lost pet report with us for continuous web monitoring.
⚠️ Spotted incorrect or outdated information? Let us know so we can review it.
Don't wait to report
The sooner you file, the sooner our system starts scanning and the better your chances of recovery. Once the report is submitted, you can focus on other things while we keep watch.
Report my lost item →Cupertino spans a large footprint with scattered parking lots, shopping areas, tech campuses, and transit hubs. Losing something here means contacting police, city services, and multiple transit operators separately, each with their own forms and hold times. The process eats hours, and your item may be claimed by someone else before you even finish calling.
ReportLost consolidates everything into one streamlined workflow. We notify the right offices instantly and maintain ongoing surveillance of local lost & found channels, community posts, and marketplaces so you don't have to check every day. Once your report is filed, the hunt runs on its own.

Frequently Asked Questions
How long do police and city services hold lost items?

What if I lost something on SamTrans or another transit service?
Contact the specific transit operator's lost & found office. SamTrans holds items for a limited time. We identify which service you used based on your description and route, and notify them on your behalf.
Where do I reclaim a lost pet in Cupertino?
Lost animals found in Cupertino may be brought to Santa Clara County Animal Services (San Martin location) or the San José city facility. Check with both frequently, especially during the first few days. Register your pet as lost with local shelters and Petco Love Lost simultaneously.
Can I search for found items online?
Yes, you can check social media groups, Nextdoor, and local lost & found pages manually, but this is time-consuming. ReportLost automates this search across the entire web for months, so you don't have to.
What information should I include in my lost item report?
Provide a detailed description (color, brand, condition, distinguishing marks), the exact location where you last had it, the date and time, and any identifying details (serial numbers, photos). ReportLost guides you through this and generates the exact details each agency needs.
Is ReportLost official or affiliated with the police?
