How ReportLost Works
You file your report
Tell us what you lost, where, and when. We guide you through the details we need to send to the right local agencies and post on community channels.
We route it to the right places
Your report goes directly to the San Bernardino County Sheriff's Department, local lost and found offices, and active Mentone community groups. You don't have to make multiple calls or figure out which precinct covers your area.
Your report keeps searching
For your entire search period, your report stays active and continues matching against new found items, community posts, and local marketplace listings. You'll get an alert if a credible match appears, so you don't have to check every day.
Where to Report in Mentone
Local channels and what to know about each
San Bernardino County Sheriff
Mentone is unincorporated, so the Sheriff's Department handles lost property reports. The nearest patrol station is in Yucaipa. You can report a lost item by calling their non-emergency line. We make sure your report reaches the right desk and includes all the details they need.
San Bernardino County Services
For general lost property inquiries in unincorporated areas, you can also reach San Bernardino County's main lost property line. We point you to the exact department that handles your situation so you're not transferred between extensions.
Local Businesses & Public Spaces
Lost a wallet or ring at Stater Bros, a local restaurant, or another Mentone business? Many keep found items for 30 to 90 days. We help you generate the exact information to include when you call, so you get answers faster.
Lost Pets
If your cat or dog is missing, time is critical. Contact the San Bernardino County Animal Care facility and post to the Redlands Lost & Found Animals Facebook group, which covers Mentone, Loma Linda, and Yucaipa. For faster coverage and a coordinated search, file a priority lost pet report with us.
Ontario International Airport
If you lost an item while traveling through Ontario (the nearest major airport), contact their Lost & Found office in Terminal 2. They hold items for a set period, so report quickly if you left something behind during your trip.
