Humboldt County Detention Center Overview
The Humboldt County Detention Center is the primary local jail for Humboldt County. The official county FAQ identifies the detention center as managed by the Humboldt County Sheriff's Office and says booking information is available by calling 775-623-6423 or online through the sheriff's website. The jail is the correct source for people recently arrested in Humboldt County, people waiting for court, people held on local warrants, misdemeanor-sentence prisoners, and other short-term detention handled by the sheriff.
The sheriff administrative office is at a different address than the jail. The Sheriff's Office page identifies Sheriff Angel Cardenas and lists the main office at 50 W. Fifth Street in Winnemucca, while the detention center is listed at 801 Fairgrounds Road. Visitors should confirm the correct jail entrance before traveling.
The Detention Division page lists jail command staff and the detention phone: source page.

That page is the county source for detention contacts, while the FAQ is the source for booking and visitation instructions.
Humboldt County Detention Center Population
County sources reviewed did not publish a rated capacity, current daily population dashboard, annual bookings, pod layout, or average daily population for the detention center. The best located count is the Prisoners of the Census 2020 Nevada correctional-population table, which counted 53 people at Humboldt County Detention Center for its 2020 vintage data. That is a population count, not an official jail capacity.
| Measure | Figure | Source |
|---|---|---|
| Correctional population count | 53 | Prisoners of the Census Nevada 2020 vintage table |
| Rated capacity | Not located | Official county detention pages reviewed |
| Current ADP | Not located | No official county dashboard located |
Look Up Humboldt County Detention Center Inmates
The correct online lookup for this county jail is the sheriff-linked CrimeGraphics portal. Use the Incarcerated People tab for current jail custody. Arrests and Warrants tabs may provide event context, but they are not the same as confirmed current custody. If a person has been sentenced to NDOC or transferred to Humboldt Conservation Camp, switch to the state offender search.
- Open the CrimeGraphics portal linked from the sheriff page.
- Select Incarcerated People for the jail roster.
- Search by name or use the available Show filters.
- Review booking number, booking date, arresting agency, arrest location, and status.
- Call 775-623-6423 if the person is not visible or the status needs confirmation.
For a broader explanation of current and past custody lookups, use the Humboldt County inmate records page.

Visiting Humboldt County Detention Center
The county FAQ says visiting is scheduled based on the detained person's name and instructs callers to contact the detention center. It also says the visit will likely occur in a secure setting. No official public schedule, dress code, child rule, visit duration, remote-video provider, or holiday rule was located in the county sources reviewed.
| Topic | Official Detail Located | Action |
|---|---|---|
| Scheduling | Scheduled based on the detained person's name. | Call 775-623-6423. |
| Published hours | Not located. | Confirm before travel. |
| Visit setting | FAQ says likely secure setting. | Ask what ID and property rules apply. |
| Calls | Calls are monitored and recorded and may create evidence. | Do not discuss case facts on recorded lines. |
The county FAQ gives the official booking and visitation channel: source FAQ.

Because the FAQ does not publish all visitor rules, phone confirmation is part of the visit process.
Mail, Phone, and Money at Humboldt County Detention Center
Official county pages reviewed did not publish a jail mail format, publications rule, commissary vendor, money-deposit vendor, phone pricing, video provider, or fee table. Do not send money, books, or packages based on third-party instructions without confirming directly with the jail. Attorney-client visits and legal mail should be coordinated through counsel and the jail.
| Service | Official Status | Safe Next Step |
|---|---|---|
| Personal mail | Not located | Call the jail before mailing. |
| Commissary | No official vendor found | Ask 775-623-6423. |
| Money deposits | No official kiosk or online provider found | Confirm accepted methods first. |
| Phone calls | Monitored and recorded per FAQ | Avoid case facts on calls. |
Booking at Humboldt County Detention Center
Humboldt County did not publish a detailed intake manual. A typical local intake includes transport, jail acceptance, identity verification, search, property inventory, fingerprints and booking photo when required, medical or mental-health screening, classification, and housing assignment. NAC Chapter 211 provides Nevada jail standards for classification, separation, sanitation, medical space, and facility conditions.
After booking, Union Township Justice Court handles many arraignments, misdemeanor matters, bail and probable-cause determinations, and felony or gross misdemeanor preliminary stages. The roster is a jail record; the formal case proceeds through the court and prosecutor path.
For families, the timing can be confusing. A person may be in the building before a public row appears online, or a public row may remain visible after release while the portal refreshes. The safest sequence is to check the sheriff roster, call the jail, and then contact the court if the question is about filed charges or hearing dates. A detainer, which is a hold or request from another jurisdiction, can also affect release even when a local bond appears available.
About Humboldt County Detention Center
County-published building details are limited. The research did not locate an official year built, rated bed count, pod layout, work-release unit, medical unit layout, parking map, accreditation note, or visitor lobby hours. The strongest official description is functional: it is the Sheriff's Office detention facility for Humboldt County, with booking and visitation information available at 775-623-6423.
The jail also sits apart from several offices users may need after an arrest. The sheriff administrative office is downtown on W. Fifth Street, the District Attorney is listed on S Bridge Street, and the Justice Court and District Court use their own court contacts. Going to the wrong building can delay a visit, records request, or hearing question, so confirm the destination before leaving.
Note: Confirm custody, visitation, and accepted property or money rules with the jail before traveling or sending funds.
