Local Businesses & Public Spaces
Wallets, rings, and personal items are often found in shops, restaurants, parks, and community centers around Alamo and turned in to management. We can advise you on what details to include when you call ahead to check their lost & found.
Lost Pets
If you've lost a cat or dog in Alamo, time matters. Contact Contra Costa Animal Services immediately; stray animals are held a minimum of 3 to 4 business days. PawBoost and local shelter databases also post found animals in the area. To file a comprehensive lost pet alert that stays active across all channels, file a priority lost pet report.

Don't let a lost item slip away
The first 24 to 48 hours matter, but so does the follow-up. Report now and set up a search that works for you for months to come.
Report my lost item →Losing your wallet, phone, ring, or other personal item in Alamo can feel isolating, especially when you're not sure where to start looking. The Sheriff's office, transit lost and found systems, and local animal services all operate separately, and calling each one takes time you may not have. ReportLost bridges that gap, connecting your loss report to every relevant agency in one go.
The real difference: after you file, your report doesn't sit idle. It stays live and automatically cross-checks new found items, lost pet postings, and community alerts for the next 12 months, so you're not refreshing websites every day hoping for good news. Once you've reported, you can breathe, knowing your item is still being searched for.

Frequently asked questions
How long do the Sheriff and transit services keep lost items?
The Contra Costa Sheriff typically holds items for a set period; check directly at Valley Station (925-837-2902). AC Transit and County Connection hold items for 30 days. After that, unclaimed items may be donated or discarded, which is why fast reporting and an active search matter.
Which transit service should I contact if I'm not sure which bus I was on?
If you were in Alamo proper, AC Transit or County Connection is most likely. Call (925) 676-7500 for County Connection or use the AC Transit online search. ReportLost can help you identify the right service based on your route and time.
What if I lost my pet in Alamo?
Contact Contra Costa Animal Services immediately at 925-608-8400 or visit in person. Stray animals are held 3 to 4 business days. Also post on PawBoost, Nextdoor, and local Facebook groups right away, and file a priority lost pet report with ReportLost to ensure your pet stays in active search databases.
Do I need to file a police report to use ReportLost?
No. You can file independently with the Sheriff if you believe a crime was involved. ReportLost works in parallel, submitting your report details to the right agencies and keeping your search active even after official filing.
Can ReportLost search bus company databases for me?
We can point you to the exact database for AC Transit, County Connection, and Tri Delta Transit, and help you know what to say when you call. What makes ReportLost different is that your report stays active and automatically alerts you if a match appears for up to 12 months, so you don't have to check manually every week.
Is ReportLost official or affiliated with the Contra Costa Sheriff?
ReportLost is an independent service, not a government agency. We partner with and submit reports to official channels like the Sheriff, transit systems, and animal control, but we're a separate company. Think of us as your advocate who ensures every agency that could help actually gets your report, and who keeps searching on your behalf after you've filed.
