How ReportLost works in Alameda
You file your loss
Tell us what you lost, where, and when. Include details like color, brand, or serial number. We generate the exact information to share with the right local authorities and channels.
We route it everywhere that matters
Your report goes to the Alameda Police Department, AC Transit (if it was on a bus), the animal shelter (if it's a pet), and relevant local groups. We handle the footwork so nothing falls through the cracks.
Automated monitoring finds your item
Our system scans Facebook, Nextdoor, local buy/sell groups, and community posts for months. The moment a credible match appears, we alert you. No need to refresh search results every day, refresh social feeds, or check marketplaces by hand.
Where to report lost items in Alameda
The official channels and what to expect from each
Alameda Police Department
Report lost or stolen property directly to the Alameda PD. You can file online for documentation, but we'll tell you exactly which precinct covers your loss location and generate the details to include.
AC Transit Lost & Found
Left something on a bus? AC Transit keeps recovered items for a holding period. You can search their inventory online or call to check. We'll make sure your report reaches their system so they're actively looking for your item.
Oakland/SFO Bay Area Airports
If your loss happened at Oakland International (OAK), items go to the airport lost & found on the 2nd floor. We'll point you to the right terminal office and escalate your report so airport staff prioritize the search.
Lost & Found Pets
If you've lost a pet, contact the Alameda Animal Shelter immediately and check their found pets list. Community groups like Alameda Lost Pet Alert also help reunite animals with owners. We can file a priority lost pet report that reaches all local animal services at once.
City of Alameda & Community
For lost items at city facilities or public spaces, the City of Alameda and local community groups can help amplify your search. We'll notify the relevant channels and monitor social media posts about found items in real time.
