Frequently Asked Questions
How long does the Walnut Creek Police Department hold lost items?
The Police Department's Lost & Found holds items for a set period before disposing of or donating them. Contact them at (925) 943-5844 (option 2) to confirm how long your specific item will be retained and to check if it's currently in their custody.
What should I do if I lost something on a County Connection bus?
Call County Connection's Customer Service at (925) 676-7500 during business hours (Mon-Fri 6:30 AM to 6:30 PM) or visit their office at their main location. Have the route number and approximate time of your trip ready. ReportLost will monitor their channels and alert you if your item is reported as found.
Can I search for my lost item on Nextdoor or Facebook before filing a formal report?
Yes, it's a good first step to check Nextdoor and local Facebook groups to see if anyone has already posted a matching found item. However, filing an official report with ReportLost ensures continuous monitoring of all these channels over weeks and months, not just one-time checks.
What happens if my item is found after I've already filed a report with ReportLost?
Once you file a report, our system monitors the web continuously. The moment someone posts about finding an item matching your description on a local community channel, marketplace, or social media, we send you an alert so you can reach out and arrange recovery.
How long does ReportLost monitor for matches?
Our automated system monitors the web for 12 months, depending on your report. This means you're covered over an extended timeframe, catching matches that surface weeks or even months after your loss.
Is ReportLost.org official or does it replace the police?
ReportLost is an independent service that complements official channels like the Walnut Creek Police Department and local authorities. We do not replace police reports or official Lost & Found processes. Instead, we coordinate with them and add continuous web monitoring so you have the best chance of recovery. For lost items, you should always file a report with the Police Department; ReportLost amplifies and extends that effort.
