Woodbury County, Iowa, has about 107,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Woodbury County Sheriff's Office and two city agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the County Attorney files charges, a case in the Iowa District Court for Woodbury County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Woodbury County
The Woodbury County Sheriff's Office is the county agency that reports arrests to the FBI for Woodbury County. It reported 274 arrests for 2025.
Arrests inside two of the county's cities are reported to the FBI by an agency of the city's own, listed here with the Census population and what each reported:
- Sioux City, 86,875 residents: 3,478 arrests reported for 2025.
- Sergeant Bluff, 5,335 residents: 50 arrests reported for 2020.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
How Many Arrests Each Agency Reports in Woodbury County
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.
- Sioux City: 3,478 for 2025, 3,670 for 2024, 2,485 for 2023, 2,507 for 2022, 3,274 for 2021 and 3,526 for 2020.
- Woodbury County Sheriff's Office: 274 for 2025, 296 for 2024, 246 for 2023, 221 for 2022, 263 for 2021 and 598 for 2020.
- Sergeant Bluff: 50 for 2020 and 66 for 2019.
Together, the two agencies with all twelve months of 2025 on file reported 3,752 arrests that year. The same agencies with both 2025 and 2024 complete reported 3,752 in 2025 against 3,966 in 2024, down 5.4 percent.
Through August 2026, the two agencies with every month so far on file reported 2,792 arrests, against 2,478 in the same months of 2025.
Sergeant Bluff reported only part of 2025 (2 months) and is left out of the totals.
Booking: Where People Arrested in Woodbury County Are Held
The county jail is where a person arrested in Woodbury County 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 2023 the jail held about 190 people, down from about 210 in 2019. Its rated capacity in 2022, the last year with a capacity figure, was 234 beds, and it ran at 87 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Woodbury County
Whether someone was arrested in Woodbury County, and what came of it, shows up in two places: the case index of the Iowa District Court for Woodbury County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at iowacourts.gov/iowa-courts/district-court/judicial-district-3/distr..., phone 712-279-6611); the County Attorney, which decides whether an arrest becomes a charge (its page is at woodburycountyiowa.gov/attorney, phone 712-279-6516).

Iowa is one of the states that lets anyone look up another person's statewide criminal history: anyone can request a name-based criminal history check online, through the Iowa Division of Criminal Investigation. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Woodbury County
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 Iowa Open Records Law (Chapter 22) the agency must answer without delay; the law sets no fixed number of days, and a delay past 20 days must be justified, and it may charge the actual cost of copying and retrieval.
- An arrest by the Woodbury County Sheriff's Office: ask its records unit, reached through the office at 712-279-6040.
- An arrest in Sioux City or Sergeant Bluff: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- A defendant who has been charged gets the report through the case: the County Attorney, 712-279-6516, handles discovery for pending cases.
- The court file of a case that was filed: the Iowa District Court for Woodbury County, through the court records page at iowacourts.gov, phone 712-279-6611.
