File a Police Report Online 

If this is an emergency, call 9-1-1 immediately.  Do not use this system. 

Welcome to the Alameda County Sheriff’s Office (ACSO) Online Police Reporting System. This service allows you to submit certain types of police reports and print a free copy for your records.

You may use this system to report the following incident types:

  • Lost Property
  • Theft – Under $950 (excluding firearms, vehicles, and license plates)
  • Vandalism
  • Vehicle Tampering – No damage occurred
  • Hit-and-Run
  • Harassing Phone Calls
  • Civil Matters
  • Supplemental Reports – Additions to an existing report

Note: If your incident involves known suspects or evidence, it cannot be filed online and will be denied, even if it falls under one of the above categories.

Before You Begin:

You may proceed with your report only if you answer NO to all of the following:

  1. Is this an emergency?
  • If yes, call 9-1-1.
  • Are there known suspects or items of evidentiary value?
  • If yes, call our non-emergency number at (510)667-7721 to speak with staff.
  1. Did the incident occur outside the areas served by the Alameda County Sheriff's Office?
    • If yes, contact the appropriate law enforcement agency where the incident occurred.
    • Did the incident occur on a state highway or freeway? 
    • If yes, contact the California Highway Patrol at 1-800-TELL-CHP (1-800-835-5247)

After You Submit Your Report:

  • A confirmation message will appear, “Your online police report has been submitted.”
  • You will receive a temporary report number (this is NOT your official report number).
  • Your report will be reviewed by Sheriff’s Office personnel for approval.
  • If denied, you will receive an email explaining the reason(s).
  • If approved, you will receive a confirmation email with your official report number.
  • You may print a copy for your records.

 

Important Reminders:

  • All reports are reviewed by ACSO personnel.
  • You may be contacted for additional information or follow-up, so it's important that we have your correct and current contact information.
  • Knowingly filing a false police report is a crime under Penal Code § 148.5(a) PC).
