📍 Johnson County WY Detention Center · Buffalo, WY

Johnson Co Jail in Buffalo, WY is a county detention facility operated by the Johnson County Sheriff's Office. Most people here are awaiting trial or sentencing - this is not a prison, and most stays are measured in days or months, not years. If someone you care about was just booked here, you have questions. Start with the one that matters most right now.

Is my family member at Johnson Co Jail?

If you are not certain they are there, the fastest way to confirm is the Johnson County inmate search or InmateAid's inmate locator, which searches across Wyoming facilities by name.

Booking takes time - sometimes several hours after arrest. If the search comes back empty, wait a few hours and try again before assuming they have been transferred somewhere else. You can also pull their arrest record and booking details to confirm the charges and facility assignment. For the most direct answer, call Johnson Co Jail at 307-684-5584.

How do I get them out on bail?

Most people booked at Johnson Co Jail appear before a judge within 24 to 48 hours. At that first appearance the judge sets the bail amount - or denies bail - based on the charges, the person's history, and whether they are considered a flight risk.

If bail is set, your family member can be released by paying the full amount or by using a bail bondsman, who typically charges 10 percent of the total as a non-refundable fee. If bail is denied or the amount is unaffordable, they remain at Johnson Co Jail until the case resolves. InmateAid's bail and bond guide walks through every option including what to do if you cannot afford a bondsman.

What is happening to them right now?

Right after arrest, your family member goes through intake at Johnson Co Jail - identity verification, medical screening, property inventory, and classification. Classification places them in a housing unit based on the charges, prior record, and intake behavior. It is not a punishment. It is how the facility manages a population that ranges from people picked up on minor warrants to individuals facing serious charges.

For the first 24 to 48 hours, phone access and visitation are typically unavailable while booking completes. Once they are assigned to a housing unit, those channels open up. InmateAid's what happens in jail guide covers the full intake process step by step so you know what to expect.

How do I talk to them by phone?

Your family member calls you - you cannot call them. Calls from Johnson Co Jail go through Global Tel Link (GTL) - ConnectNetwork and all calls are recorded except attorney calls. Set up a Global Tel Link (GTL) - ConnectNetwork account before the first call so the connection goes through without delay.

Phone contact is more important than most people realize going into this. A regular call - even a short one - makes a measurable difference in how someone holds up inside. Do not let the setup friction stop you. Visit InmateAid's jail calls page for step-by-step account setup, current rate information, and tips for keeping funds available.

When can I visit and what are the rules?

Visitation hours at Johnson Co Jail are set by the facility and can change without much notice. Before making the trip, call 307-684-5584 to confirm current hours, any advance registration requirements, and what you are allowed to bring.

The most common mistake families make is showing up without confirming first - and that results in a wasted trip and a missed visit for your family member. General rules across most Wyoming county jails: dress conservatively, avoid colors that resemble inmate uniforms, leave your phone in your car, and bring valid government-issued ID. Children may be permitted with specific requirements depending on the facility. InmateAid's visitation guide has a full checklist you can run through before you go.

An Inmate here can choose 5 adult visitors to visit them during the designated times. When an inmate chooses 5 visitors, Detention Staff will validate the approval of said visitors. Listed visitors will have to provide valid ID at the time of visitation. This facility utilizes a video visitation system.

All visitors will conduct themselves in a courteous, polite, and professional manner. Please be respectful of other visitors and their visitation time.

Any visitor that appears, or is found to be under the influence of anything, will immediately have to leave.

All visits will be monitored and recorded. No vulgar language or inappropriate behavior will be tolerated. If this is found to be breached, the visitation will be terminated for the session and can be indefinite.

Wednesday A and C Blocks, 7 pm to 9:30 pm
Thursdays B, D, and E Blocks 7 pm to 9:30 pm

How do I put money on their books?

Money on the books - also called the commissary or trust account - gives your family member access to hygiene items, snacks, phone time, and postage. It is one of the most practical things you can do and it has a direct effect on their daily comfort.

Johnson Co Jail accepts deposits through approved channels that typically include online deposit, phone deposit, or a kiosk at the facility. Use your family member's full legal name and booking number exactly as they appear in the jail's system - any error in the name or number will delay or reject the deposit. InmateAid's send money page lists the specific deposit methods accepted at Johnson Co Jail and walks through the process.

How do I send letters or photos?

A letter or a printed photo costs almost nothing to send and means far more than most people outside appreciate. Johnson Co Jail accepts incoming mail addressed to your family member at 639 Fort St. Put their full legal name and booking number on every piece of mail.

Standard rules at most Wyoming county jails: plain white paper only, no staples, no glitter, no stickers, no colored ink. Photos should be standard print size with nothing written on the back. Mail that does not meet the facility's standards will be rejected - and the facility may not notify you that it was. Keep it simple.

InmateAid's send mail service lets you write and send directly from your phone or computer. We print on approved stock and mail it for you, so rejection for formatting is not a risk.

Books and magazines must come new, ordered directly from the publisher or through an online retailer - not shipped from your home address. Facilities require this to prevent contraband. Order through Amazon or directly from the publisher. Anything shipped from a personal address will be turned away.

County jail time is hard in a way that is different from anything else. The uncertainty - not knowing how long, not knowing what comes next - wears on everyone. What you can control is the connection. Calls, letters, visits, money on the books. Every one of those things tells your family member that someone out here is paying attention and is not going anywhere.
