Explore Law Enforcement Survey Responses

To determine the nature and extent of law enforcement agencies' ALPR programs across the State, we surveyed 391 police and sheriff departments. The interactive map and graphics below present the survey responses. Select a county, state assembly district, or state senate district on the map to view a list of the region's agencies and their usage of ALPR systems. When you select a region, a summary graphic shows the retention periods and ALPR vendors the agencies within that region reported that they use. The survey responses were self-reported, and we did not verify their accuracy. The following 10 agencies did not respond to our survey: Anderson Police Department, Barstow Police Department, Del Norte County Sheriff's Office, Lakeport Police Department, Lodi Police Department, Mendocino County Sheriff's Office, Mount Shasta Police Department, Oceanside Police Department, San Francisco Sheriff's Department, and Siskiyou County Sheriff's Department.

Note: Police and sheriff departments may use more than one ALPR vendor. Three responding agencies that use ALPR systems did not indicate a retention period for their information: Bakersfield Police Department, Fountain Valley Police Department, and Pasadena Police Department. Further, Pasadena Police Department did not indicate which vendor provides its ALPR services.
