American Canyon, California, in Napa County, has about 22,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Superior Court of California, County of Napa. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in American Canyon
The FBI lists American Canyon with an arrest reporting agency of its own, filed as American Canyon Police Department. It reported 518 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Napa County Sheriff's Office is the county agency. It reported 324 arrests for 2025.
The FBI's agency list also places these agencies in Napa County: Union Pacific Railroad in Napa County and the Napa Special Investigations Bureau (other); Napa State Hospital (state agency); the Highway Patrol's Napa Area Office (state police).
How Many Arrests American Canyon Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- American Canyon: 518 for 2025, 351 for 2024, 414 for 2023 and 904 for 2022.
American Canyon's 518 arrests in 2025 were up 48 percent from 351 in 2024.
Through August 2026, American Canyon reported 258 arrests, against 314 in the same months of 2025.
Across Napa County, the six agencies with all twelve months of 2025 on file reported 2,071 arrests between them.
Booking: Where People Arrested in American Canyon Are Held
The county jail is where a person arrested in American Canyon and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 220 people, down from about 250 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 275 beds, and it ran at 92 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Napa County Sheriff's Office at app.napacounty.gov/CJNet/Public/BookingReport (page title: Jail Booking Report | County of Napa), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the California Department of Corrections and Rehabilitation lists its inmates at cdcr.ca.gov/search.
How to Find Out About an Arrest in American Canyon
An arrest in American Canyon can be traced in two places, depending on where the case stands: the custody page of the Napa County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Superior Court of California, County of Napa, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at napa.courts.ca.gov/research-records, phone (707) 299-1140).
California does not let the public search another person's statewide criminal history. The record kept by the California Department of Justice goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in American Canyon
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the California Public Records Act the agency must answer within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time.
