Hamilton County Jail Roster Overview
No confirmed public Hamilton County web roster was found on the official sheriff or jail pages during the research pass. The official Hamilton County Sheriff IA mobile app is the Hamilton-specific digital path that advertises an inmate-search feature, with listings at the Apple App Store and Google Play. The Apple listing names Hamilton County Sheriff's Office, IA as developer and shows version history in 2025; the Google listing names OCV, LLC as developer and shows 500+ downloads. Because the in-app roster form was not inspectable from web listings, Hamilton County pages should not promise specific search fields, booking-photo displays, bond fields, or release-retention rules.
Hamilton County Jail records are local custody records. They are not the same thing as Iowa DOC prison records, federal Bureau of Prisons records, ICE detention records, or court dockets. A person arrested in Webster City or elsewhere in Hamilton County may start at the county jail, appear later in Iowa Courts Online, move to Iowa DOC after a prison sentence, or be held under U.S. Marshals authority while physically housed at the jail.
How Do I Find Someone in the Hamilton County Jail?
Start with official Hamilton County channels before using statewide or federal locators. The Hamilton County Jail page gives the jail phone, visitation, commissary, and communication rules, while the mobile app listings advertise inmate search. If the app does not show the person or cannot be checked, call the jail rather than relying on unofficial inmate sites.
- Open or install the Hamilton County Sheriff IA app and look for the advertised inmate-search feature.
- Search using the identifying information the app requests. The field labels were not visible from public web sources.
- If the person is not found, call Hamilton County Jail at 515-832-8629 with the full legal name, date of birth or age, and approximate arrest date.
- For copies or older booking information, contact the Sheriff's Office at 515-832-9500 or make an Iowa Code chapter 22 public-records request.
- If the person was sentenced to prison, check the Iowa DOC Offender Search instead of the county jail.
- For federal sentenced custody or immigration detention, use the BOP locator or ICE detainee locator.
- For custody or case alerts, use Iowa VINELink.
Hamilton County Roster Search Fields
The Hamilton County Sheriff IA app listings say the app includes inmate search, but the in-app search form, buttons, filters, and result layout were not available from public web pages. Treat the table below as a field inventory of what was and was not confirmed, not as a claim that the app accepts a particular name, booking number, or date filter.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| App inmate-search fields | Not inspectable from web | Not inspectable | Official app-store listings advertise inmate search, but field labels were not visible. |
| Last name / first name | Not confirmed | Not confirmed | Do not assume a name-only interface until the app is inspected directly. |
| Booking number | Not confirmed | Not confirmed | No Hamilton County web roster or booking-number search field was confirmed. |
| Release, mugshot, bond, or charge filters | Not confirmed | Not confirmed | The research did not inspect app result fields, mugshot display, release display, or roster retention. |
What Does a Roster Record Show?
No field-level Hamilton County public web roster profile was confirmed. For Hamilton County inmate records, ask whether the app, jail staff, court docket, or a written records response can provide the following items. A jail record documents custody and booking. A court record documents filed charges and case progress, so the two may not match at every point in the process.
| Field | What It Shows |
|---|---|
| Custody status | Whether the person is currently held, released, transferred, or subject to a hold, if releasable. |
| Booking date or time | The intake date or approximate booking event, if available in the releasable record. |
| Arresting or booking agency | May identify Hamilton County Sheriff's Office, Webster City Police, Iowa State Patrol, another local agency, or a federal/state authority. |
| Charges or arrest allegations | Booking allegations are accusations only; defendants are presumed innocent unless and until proven guilty in court. |
| Bond or hold status | May show bond amount, bond type, no-bond status, warrant hold, detainer, or other release limits if releasable. |
| Court case number or date | Use Iowa Courts Online as the court fallback once a case is filed. |
| Housing or visitation schedule | Call the jail because visitation depends on housing assignment and the inmate's scheduled time. |
| Booking photo | Not confirmed on an official Hamilton web roster; request through sheriff/public records if not visible in the app and if releasable. |
Finding County, State, Federal, and ICE Inmates
Hamilton County Jail can hold prisoners for Hamilton County, the U.S. Marshals Service, the Federal Bureau of Prisons, the State of Iowa, and surrounding counties as needed. That local housing role does not make the county app a complete prison, federal, or immigration locator. Use the county path for recent local custody, Iowa DOC for sentenced state custody or supervision, BOP for federal sentenced custody, and ICE for immigration detention.
| Custody | Where to Look |
|---|---|
| Pretrial or short local sentence | Hamilton County Sheriff IA app, then Hamilton County Jail at 515-832-8629. |
| Booking record copy or older jail record | Hamilton County Sheriff's Office at 515-832-9500 or an Iowa Code chapter 22 records request. |
| Filed criminal case | Iowa Courts Online for public docket information. |
| Sentenced state prisoner or supervision | Iowa Department of Corrections offender search, which includes County of Commitment as a field. |
| Federal sentenced inmate | Federal Bureau of Prisons inmate locator. |
| Federal pretrial detainee | Call the jail for local housing, then use federal court or U.S. Marshals channels for case details. |
| Immigration detention | ICE Online Detainee Locator by A-number or biographical information. |
| Notifications | Iowa VINELink for custody and case notifications. |

Official Jail Page Reference
The county's official Hamilton County Jail page is the source for the jail phone, capacity, visitation window, commissary vendor, and Reliance phone/video information.
The page supports the local contact chain, but it does not replace the app's advertised inmate-search feature or statewide systems such as Iowa DOC, BOP, ICE, Iowa Courts Online, or VINELink.
Booking Process in Hamilton County
Hamilton County does not publish a detailed booking manual, so the safest description is a practical custody flow built from local jail facts and Iowa jail standards. A person may be arrested by the Hamilton County Sheriff's Office, Webster City Police, Iowa State Patrol, another local agency, or an outside authority. The confirmed local intake location is Hamilton County Jail at 2300 Superior Street, Suite 8, Webster City.
During intake, jail staff verify identity, booking reason, warrants, holds, and court paperwork. Iowa jail standards require admission, classification, security, property, and search procedures. The 2025 PREA audit describes six housing units and minimum, medium, and maximum custody/security levels. Youthful inmates are not held at the jail, so juvenile matters should not be treated as a Hamilton County jail roster search.
If a new arrest does not appear in the app, call the jail at 515-832-8629. No official Hamilton source gave a roster refresh rate, app visibility timing, or release-retention period. For filed charges and hearing information after booking, use Iowa Courts Online once the criminal case appears.
Public Records Requests for Jail Records
Iowa Code chapter 22 generally gives people the right to examine and copy public records unless a confidentiality exception applies. Iowa Code section 22.7(5) can affect peace officer investigative reports, while section 22.7(9) addresses criminal identification files and public arrest or criminal-history information. For a Hamilton County jail-record request, contact the Sheriff's Office and ask for releasable booking information under chapter 22.
A focused request can ask for the booking record for a named person, approximate booking date, booking agency, charges or arrest allegations, bond or hold status, court case numbers, release status, and any booking photo if releasable. If a portion is withheld, ask the custodian to identify the Iowa Code basis for withholding or the correct agency if Hamilton County is not the record holder.
Visitation Hours and Rules
Hamilton County Jail visitation depends on the inmate's housing assignment and approved visitor list. The inmate must submit each visitor's name, date of birth, address, Social Security number, and relationship 24 hours before the scheduled visit. Call the jail before travel because approval does not guarantee a visit if the inmate is in court, moved, disciplined, in medical care, or affected by a lockdown.
| Visit Type | Schedule / Availability | Approval | Cost / Notes |
|---|---|---|---|
| Inmate visiting hours | 1:30 p.m.-5:30 p.m., Monday-Friday | Depends on inmate housing and jail schedule | Call 515-832-8629 for the inmate's scheduled time. |
| Onsite video visitation | One hour once weekly at the inmate's scheduled time/day | Approved list required 24 hours ahead | Free onsite hour. |
| Remote video calling | 8:00 a.m.-10:00 p.m. | Reliance wallet/communicator setup | $0.25 per minute. |
| Attorney visits | Not published in the jail page schedule | Contact jail | Call the jail for attorney visit handling. |
How to Contact a Hamilton County Inmate
Jail staff are not permitted to deliver personal messages unless an emergency condition exists. Inmates may make collect calls or use phone cards through Reliance. The county page lists phone cards at $10 for 20 minutes or $20 for 40 minutes, text messages at $0.09 per message, voice calls at $0.25 per minute, video calls at $0.25 per minute, and video-call availability from 8:00 a.m. to 10:00 p.m. The voicemail number for inmates is 515-209-2393 and is available 24 hours a day.
Mail and money sent by mail should be addressed to the inmate name at Hamilton County Jail, 2300 Superior St. Suite #8, Webster City, IA 50595. Envelopes must include a complete return address. People who have been transferred to Iowa DOC should use DOC mail, money, phone, and visitation rules instead of the Hamilton County Jail address.
Commissary and Inmate Funds
Hamilton County Jail uses TurnKey Corrections / Inmate Canteen for commissary. The jail page says an Inmate Canteen kiosk is available at the Sheriff's Office 24/7 and accepts cash and debit or credit cards. Online access is available through Inmate Canteen from a phone, tablet, or computer. Inmates who follow jail rules may order commissary, including phone cards and other needs, with order deadlines listed by the county as Monday and Wednesday by 10 p.m.
Note: Confirm custody with Hamilton County Jail before sending funds, and do not assume the commissary kiosk can post bond.
