Butte Jail Roster: Butte-Silver Bow Inmate Search & Booking

A person can also be arrested by one agency, housed at the detention center, appear before a different court and have another agency’s hold. Do not assume the arresting agency, jail and court are interchangeable.

• Correct legal first and last name
• Possible middle initial or middle name
• Former, maiden or hyphenated surname
• Approximate age or date of birth
• Approximate arrest or booking date
• Arrest location or law-enforcement agency
• Known court or case number
• Whether state or federal custody is possible

No fixed “roster updates every X minutes” interval is stated on the official detention page reviewed for this update, so this guide does not invent one.

Adults arrested and delivered to the Butte-Silver Bow Detention Center go through intake and booking. The county says booking includes questions from booking staff, photographs and fingerprints. After booking, an arrestee is allowed to use the phone to contact a bondsman, family member or friend.

If the person cannot bond out or the matter is not bondable, the facility uses its classification process to determine housing. The county describes that process as a risk assessment that can consider history, conduct in custody and physical or mental disabilities.

The county says bond amounts for misdemeanor matters are determined by the court. Felony charges and some “no bond” matters require the defendant to see a judge before a bond amount can be set.

The official page currently lists cash, credit card, cashier’s check and a surety bond through a licensed bonding agent as accepted forms. Cash bonds may be posted at the detention center. The county also states that a person age 18 or older may post a bond on behalf of the arrestee.

Montana Court Public Access Portals

The Montana Judicial Branch provides separate public-access portals for District Courts and Courts of Limited Jurisdiction. These portals are searchable case indexes; they should not be confused with the jail roster or with the complete official case file maintained by the court.

Open Montana Public Access Portal information.

Justice Court records fees

Butte-Silver Bow Justice Courts currently publish a $10 search fee per name. The court also publishes copy charges and says original records cannot be removed from the office. Review the live court page before ordering because fees can change.

What about warrants?

A warrant is not proof that a person is currently incarcerated. During this source review, a clearly identified current standalone Butte-Silver Bow public warrant-search portal was not found on the county’s official website. For a warrant question, use the appropriate court or Butte-Silver Bow Law Enforcement rather than interpreting absence from the jail roster as proof that no warrant exists.

The county says inmates are responsible for setting up visitation on their assigned day. Visitors must have photo identification. Cell phones are not allowed, and the county states that the visitor’s vehicle key is the only item allowed in.

Because housing, restrictions or facility operations can change, verify the inmate’s current housing and visit availability before traveling.

The current county mail/money page states that inmates cannot receive ordinary incoming phone calls. It says inmates can make collect calls and/or purchase prepaid calling cards from commissary.

The county’s inmate communication page links users to NCIC for account setup. NCIC offers correctional calling, messaging and related communication services. Check the facility inside the provider system before funding an account because provider options and charges can change.

Butte-Silver Bow’s mail guidance says the new non-legal mail process took effect June 1, 2025. Ordinary personal mail is routed to a processing location where it is scanned and delivered electronically to the inmate.

Published non-legal mail limits

• Include the inmate’s name and Sheriff’s Office inmate number.
• Include the sender’s return address.
• Mail must fit within 8.5 × 11 inches.
• No more than five pages per mailing.
• Only the front side is scanned, so writing on the back may not reach the inmate.
• A maximum of one photo is allowed per mailing under the published guideline.
• Items sent to the processing address are scanned for electronic delivery and the physical items are destroyed rather than returned.

Legal and medical mail

Legal and medical mail should not be sent to the Texas scanning address. The official guidance directs those categories to the facility at 155 W Quartz St, Butte, MT 59701.

Packages and publications

The county says packages must come directly from the manufacturer or company. It publishes the detention facility address for packages and requires the inmate’s first and last name plus sender identification and return address.

Before mailing anything, review the current official Inmate Mail, Money and Phone page because mail rules are especially sensitive to security-policy changes.

The county says inmate funds first satisfy the booking fee and any medical copay fees owed. Only remaining money is available for commissary purchases.

The county currently says commissary money can be mailed directly to the detention center in the form of cash or cashier’s check only. It specifically warns not to place a personal letter in the same mailing as commissary funds because the letter will be destroyed.

Butte-Silver Bow says health services are available to inmates and identifies a mental-health therapist, registered nurse and medical doctor as part of care. Emergency dental care is also available.

The facility states that medical services and prescription medication can carry a copay of up to $10. It says there is no copay for mental-health services.

For an urgent medication or health concern, contact the detention center and ask how current medical information should be communicated to the appropriate staff. Do not mail medication or assume family members can directly obtain protected medical information.

Mugshots and booking photos

Official roster documents may display a booking photograph. A photo can help distinguish people with similar names, but it does not establish guilt, conviction or final case outcome.

Do not rely on copied mugshot websites for current legal status. If the question is what happened in court after the arrest, use the official court record.

Background and criminal-history checks

Butte-Silver Bow’s official background-check guidance explains that public criminal-history information can be limited by Montana privacy rules and that some records—such as police reports, court transcripts, warrants and probation/parole information—should be requested from the appropriate local agency or court.

Review Butte-Silver Bow background-check guidance.

Evidence property is a separate process

Property held as law-enforcement evidence is not the same as an inmate’s personal jail property. The Butte-Silver Bow Evidence Unit publishes its own release requirements, identification rules and pickup process.

• Opening Butte County, California instead of Butte-Silver Bow, Montana.
• Opening an old dated roster PDF from search results instead of the newest county link.
• Assuming a matching name alone confirms identity.
• Treating a booking charge, mugshot or warrant as a conviction.
• Using the jail roster as a substitute for the controlling court record.
• Posting bond before confirming the current amount and additional holds.
• Using pre-2025 personal-mail instructions instead of the current scanning process.
• Sending personal mail to the jail address when the current non-legal mail rule requires the Texas processing address.
• Sending commissary funds with a personal letter.
• Assuming the first published jail phone number is correct for every task.
• Assuming “not on roster” means the person has no case, warrant or other custody status.

• An arrest is not a conviction.
• A booking charge can later be amended, dismissed or resolved differently in court.
• A warrant does not establish current incarceration.
• A roster screenshot can become stale quickly.
• A booking photograph does not show the final legal outcome.
• Do not use jail information to harass, threaten, shame or stalk a person.
• Do not publish sensitive victim, witness, family or medical information found through other records.
• Use official court records when the question is guilt, dismissal, plea, sentence or final disposition.
