How ReportLost works in Martinez
You submit your loss
Tell us what you lost, where, and when. We gather the details needed to alert the right places in Martinez and Contra Costa County.
We route it to the right channels
Your report reaches the Martinez Police Department, animal shelters if needed, County Connection and other transit systems, and local Facebook groups and community forums where people report found items.
Automated monitoring finds matches
Our system scans the web daily, searching community posts, marketplace listings, animal registries, and local groups for matches. As soon as a credible "found" posting appears that fits your description, location, and timeline, we alert you. No need to refresh pages or check groups yourself every morning.
Where to report a lost item in Martinez

Martinez Police Department
File a lost property report with the Martinez PD. Non-emergency calls are best; dispatch is available 24/7, though the front desk is open Monday to Friday, 8am to 4:30pm. We determine which precinct covers your location and generate the specifics you'll need when you call or visit.

The City of Martinez front desk can direct you to the right department or confirm lost-and-found procedures. Many small items found on city property end up logged here or at the Police Department.
County Connection & Transit
