How ReportLost Works
You submit your loss
Describe what you lost, where, and when. We gather all the details we need to route your report correctly.
We alert the right places
Your report goes directly to Millbrae Police, relevant city departments, transit authorities, and the local community channels that matter for your situation.
Your report keeps searching
For your entire search period (12 months), your report remains active and matches against new found items posted by individuals, businesses, and local services. You get alerted if a credible match appears, so you don't have to check Facebook groups and lost & found pages every day.
Where Your Lost Item Might Be
Report it to the official channels, or let us handle the coordination.
Millbrae Police Bureau
The Millbrae Police Bureau maintains a lost and found for items turned in by residents and businesses. You can file a report online or visit in person. We generate the report and tell you exactly which precinct to follow up with and what case details to reference.
Millbrae City Hall
City Hall can direct you to the right department depending on where your loss occurred, whether it's a public facility or city property. We point you to the exact office and contact to reach.
SamTrans Lost & Found
If you left something on a bus or SamTrans vehicle in the area, submit a lost item report. The service typically locates items within 48 hours. We make sure your item description matches what SamTrans is expecting.

Millbrae is minutes from SFO. Items left in terminals, gates, or baggage can be reported through the airport's lost and found service. If your loss happened during travel, we clarify which airport facility to contact.

Report my lost item →Losing something in Millbrae means navigating several separate channels, each with its own hours and procedures. A lost wallet might end up with the Police Bureau on Magnolia Avenue, a set of keys in a shop's drawer, and a lost pet at the San Mateo Animal Control facility. Without a clear way to coordinate reports across all these places, items can slip through the cracks.
ReportLost bridges that gap. One form, sent to all the right local services and community networks at once. Then your report stays in the system, actively matching new found postings against your description for months, while you focus on your day. No need to refresh community boards or call back repeatedly, we handle the ongoing search for you.
