Natrona County Jail Inmate Lookup gives families, lawyers, and the public instant access to current inmate records. The online system shows booking status, housing location, bond details, and expected release dates. Users can search by name, booking number, or date through the official county portal or third-party tools. The jail connects to Wyoming’s statewide offender database, so searches include federal, state, and local records. This ensures accurate, up-to-date results for anyone checking on a detained person.
The detention center runs 24 hours a day with three daily lock-downs: 5:30–6:00 AM, 11:00 AM–1:00 PM, and 4:00–6:00 PM. During these times, public services stop for safety checks and maintenance. Mail must go to 1100 Bruce Lane, Casper, WY 82601, and include the inmate’s full legal name and ID number. Electronics, cash, and other banned items are not allowed. The facility holds about 370 people daily in a modern building that opened in 1982 with a max capacity of 167 inmates.
How to Use the Natrona County Jail Inmate Lookup System
Start by visiting the official Natrona County Jail website. The roster updates in real time, so you see the latest bookings and releases. Enter the person’s first and last name, or use their booking number if you have it. You can also filter by date range to narrow results. Each record shows charges, bond amount, housing unit, and next court date. If no match appears, the person may not be in custody or could be held elsewhere.
For faster help, call the jail directly at 307-235-9524. Staff can confirm an inmate’s status during business hours (7:30 AM–4:30 PM). Always have the full name and date of birth ready. Avoid calling during lock-down periods when lines may be busy. The phone line is best for urgent questions not covered online.
Third-party sites like Jail Exchange and PrisonRoster also list Natrona County inmates. These tools often include mugshots, charge descriptions, and visitation rules. While helpful, always double-check info with the official county site. Data on external platforms may lag by a few hours.
Official Natrona County Jail Roster Portal
The primary source for inmate data is https://natronacountyjail.org/. This site is maintained by the Natrona County Sheriff’s Office and updated every few minutes. It includes a search bar, filter options, and links to related services. You’ll find contact numbers, mailing addresses, and rules for visits and mail.

Each inmate profile displays key details: full name, photo, booking date, charges, bond amount, and housing block. Some entries show court dates and attorney contact info. If a person has been released, the record notes the release date and reason. This transparency helps families stay informed without repeated calls to the jail.
The site also explains how to send money, mail, or request medical care for an inmate. It lists approved items for packages and banned substances. For example, only paperback books from publishers are allowed—no hardcovers or used books. All mail is inspected before delivery.
Jail Exchange: Alternative Inmate Search Tool
Jail Exchange offers a user-friendly way to find Natrona County inmates. Visit their page for the detention center to view names, photos, charges, and release dates. The site includes the jail’s phone number (307-234-3757) and physical address: 201 North David Street, Casper, WY 82601.
Every year, local law enforcement makes around 7,400 arrests in Natrona County. The jail averages 370 detainees per day. Jail Exchange compiles this data into easy-to-read profiles. You can sort by name, charge type, or booking date. The site also explains visitation rules and how to deposit funds into an inmate’s account.
While useful, remember that third-party sites may not update as quickly as the official roster. Always verify critical info—like release dates or bond amounts—with the county portal or by phone. Jail Exchange is best for quick checks or when the main site is down.
PrisonRoster: Another Option for Inmate Records
PrisonRoster provides a searchable database for Natrona County Detention Center inmates. Their page includes the jail’s phone number (307-235-9282) and links to booking details. Each entry lists the inmate’s ID number, custody level, and housing assignment.
The site emphasizes the jail’s mission: community safety, staff security, and inmate welfare. It covers both pre-trial detainees and sentenced individuals. Users can learn how to schedule visits, send mail, or request medical attention for a loved one.
PrisonRoster is helpful for people who prefer a simpler interface. However, it lacks some features found on the official site, like real-time updates or links to court records. Use it as a backup when primary sources are unavailable.
Wyoming Statewide Offender Lookup Integration
Natrona County’s system connects to the Wyoming Offender Lookup, a centralized database for all state jails and prisons. This means your search can include federal inmates, state prisoners, and those held in other counties. To use it, go to https://natronacountyjail.org/inmate-search/ and select “Wyoming Offender Lookup.”
You can search by name, ID number, or offense type. Results show current location, sentence length, and parole eligibility. This is especially useful if someone was transferred from Natrona County to a state prison. The tool also lists contact info for other Wyoming facilities, like Albany County (307-755-3521) and Big Horn County.
Because this system covers multiple jurisdictions, it reduces the need to check each jail separately. It’s the most complete way to track someone through Wyoming’s justice system.
StateCourts.org: Legal and Inmate Resources
StateCourts.org offers a dedicated Natrona County inmate search page. It includes addresses and phone numbers for key offices: the District Court at 235 Curtis St., Evansville, WY 82636 (307-234-1270), and the Mills Police Department at 4800 W Yellowstone Hwy, Mills, WY 82644 (307-266-4796).
Users can search by name, date of birth, or booking number. Results show charges, bond amounts, and upcoming court dates. The site also links to public defense contacts, victim assistance programs, and bail bond services. This gives a full picture of the legal process for each detainee.
StateCourts.org is ideal for attorneys, families, or advocates needing detailed case info. It bridges the gap between jail records and court proceedings.
Mail and Package Rules for Inmates
All mail must be sent to 1100 Bruce Lane, Casper, WY 82601. Include the inmate’s full legal name and ID number on every envelope. Only letters, photos, and approved paperback books are allowed. Do not send cash, checks, or electronics—these will be rejected.
Packages must come from publishers or retailers. Used books, magazines, or homemade items are not permitted. All mail is opened and inspected. If something violates policy, it’s returned or destroyed. For questions, call 307-235-9524 before mailing anything.
Remember: sending contraband can lead to disciplinary action against the inmate. Stick to the approved list to avoid delays or bans.

The Natrona County Detention Center is at 1100 Bruce Ln., Casper, WY 82601. The public lobby is open from 7:30 AM to 4:30 PM, Monday through Friday. Visitors can check in, ask questions, or submit paperwork during these hours.
Call 307-235-9524 for roster inquiries or general info. The jail’s mission focuses on community safety, secure custody, and inmate welfare. It houses pre-trial detainees, sentenced individuals, and those awaiting transfer.

Visitation Guidelines and Scheduling
Visits must be scheduled in advance. Check the official website or call the jail for current rules. Bring valid photo ID—driver’s license, passport, or state ID. Minors need a parent or guardian present.
Visitation hours vary by housing unit. Most visits occur between 8:00 AM and 4:00 PM, excluding lock-down times. Dress modestly: no revealing clothing, hats, or gang-related symbols. Physical contact is limited to a brief hug at the start and end.
Each inmate gets one visit per week, lasting up to 30 minutes. Late arrivals may lose their slot. If you miss two scheduled visits, you may be banned for 30 days.
How to Send Money to an Inmate
Funds can be added online, by phone, or in person. Use the official jail portal or approved kiosks in the lobby. Accepted methods include credit/debit cards and cash (at kiosks only).
There’s a small fee per transaction. Money appears in the inmate’s account within 24 hours. Use the inmate’s full name and ID number when depositing. Never send cash through the mail.
Inmates can use funds for commissary items, phone calls, or medical co-pays. Balances carry over if someone is transferred or released.
Medical and Mental Health Services
The jail provides basic medical care, including prescriptions, emergency treatment, and mental health support. Requests for care must be submitted in writing. Staff review them within 24 hours.
Serious conditions may require outside hospital visits. All costs are billed to the inmate or their family unless covered by insurance. The facility has a dedicated medical wing with trained personnel.
Mental health counselors are available for evaluations and therapy. Inmates with severe needs may be transferred to specialized facilities.
Educational and Reentry Programs
The detention center offers GED classes, life skills workshops, and job training. These programs aim to reduce recidivism and support successful reentry. Participation is voluntary but encouraged.
Partners include local colleges and nonprofit organizations. Certificates earned in jail can help with employment after release. Some inmates qualify for early release based on program completion.
Reentry services include help with ID documents, housing referrals, and job placement. Staff connect inmates with community resources before discharge.
Historical Background of the Facility
The current Natrona County Detention Center opened in 1982 with a 167-bed capacity. It replaced an older jail built in 1890 on South David Street, which burned down in 1979. The new building features upgraded security, medical units, and visitation areas.
Over the years, the center added educational programs, vocational training, and better healthcare. It now serves as a model for rural detention facilities in Wyoming.
The original jail housed inmates for nearly a century. Its destruction led to modern safety standards and improved living conditions. Today’s facility balances security with humane treatment.

Frequently Asked Questions
Many people have questions about how the Natrona County Jail Inmate Lookup works, what information is available, and how to contact the facility. Below are detailed answers to the most common concerns.
How accurate is the online inmate roster?
The official Natrona County Jail roster is updated in real time, usually every few minutes. This means the information you see reflects the most recent bookings, releases, and status changes. However, third-party sites like Jail Exchange or PrisonRoster may not sync as quickly and could show outdated data. For critical decisions—such as posting bond or planning a visit—always verify details by calling the jail directly at 307-235-9524. The roster includes full names, booking dates, charges, bond amounts, and housing locations. If someone appears listed but you believe they should be released, contact the sheriff’s office immediately. Errors are rare but can happen during manual data entry. The system is designed for transparency and public access, so families and attorneys can stay informed without unnecessary delays.
Can I search for an inmate using only their first name?
No, the Natrona County Jail Inmate Lookup requires at least the full first and last name to return results. Partial names or nicknames will not work due to privacy and accuracy concerns. If you’re unsure of the spelling, try common variations or contact the jail with additional details like date of birth or last known address. The system does not support wildcard searches or phonetic matching. For example, searching “Mike” won’t find “Michael.” Always use the legal name as it appears on official documents. If the person recently changed their name, use the version under which they were booked. This ensures you get the correct record and avoid confusion with others who share similar names.
What should I do if I can’t find an inmate in the system?
If your search returns no results, the person may not yet be processed into the jail, could be held in a different facility (such as a state prison or federal detention center), or their record might be temporarily restricted for legal reasons. First, wait a few hours and try again—bookings can take time to appear online. Next, call the Natrona County Detention Center at 307-235-9524 and provide the individual’s full name and date of birth. Staff can confirm whether they’re in custody and, if so, where. You can also check the Wyoming Offender Lookup for statewide records. If the person was recently arrested, they might still be at the police station or courthouse. Always have accurate identifying information ready when calling to speed up the process.
Are mugshots and photos publicly available?
Yes, most inmate profiles on the official roster and third-party sites include booking photos (mugshots). These images are taken during intake and become part of the public record. They help verify identity and are often used by media outlets or background check services. However, photos of minors or victims of certain crimes may be withheld for privacy or safety reasons. The jail does not release additional personal photos unless authorized by the inmate or their attorney. Be aware that once published online, mugshots can remain accessible indefinitely, even after release. If you believe a photo was posted in error or violates privacy rights, contact the sheriff’s office to request removal—though success is not guaranteed under Wyoming’s public records laws.
How do I report incorrect information on an inmate’s record?
If you spot a mistake—such as wrong charges, bond amount, or release date—contact the Natrona County Sheriff’s Office immediately at 307-235-9524. Provide your name, relationship to the inmate, and specific details about the error. Include any supporting documents, like court papers or attorney correspondence. Staff will review the case and correct the roster if needed. Most errors stem from delayed data entry between courts and the jail, so updates may take 24–48 hours. For serious inaccuracies affecting legal rights (e.g., mistaken identity or false charges), consult an attorney right away. The jail relies on official court filings, so corrections often require coordination with prosecutors or judges. Always follow up in writing if the issue isn’t resolved by phone.
Can I send care packages to an inmate?
No, Natrona County Detention Center does not allow care packages from outside sources. Only letters, photos, and approved paperback books sent directly from publishers are permitted. Items like clothing, snacks, hygiene products, or electronics are banned. Inmates can purchase these through the commissary using funds deposited into their account. This policy ensures safety, prevents contraband, and maintains fairness. All incoming mail is inspected, and prohibited items are confiscated. If you want to support an inmate, send money online or via the lobby kiosk. For special medical or religious needs, submit a written request to staff for approval. Never attempt to sneak in unauthorized items—it can result in loss of visitation privileges or disciplinary action against the inmate.
What happens during administrative lock-downs?
Lock-downs occur three times daily: 5:30–6:00 AM, 11:00 AM–1:00 PM, and 4:00–6:00 PM. During these periods, all non-essential activities stop so staff can conduct headcounts, safety inspections, and facility maintenance. Visits, phone calls, and mail processing are paused. Inmates remain in their cells, and public services like lobby access are closed. These routines ensure order, prevent escapes, and allow thorough checks of equipment and records. Lock-downs are mandatory and cannot be skipped, even for emergencies. Families calling during these times may hear a busy signal or voicemail. Plan visits and calls outside these windows to avoid delays. The schedule is posted on the jail’s website and posted signs.
