How to Find an Inmate in Arizona
If someone you love was just arrested or sent to prison in Arizona, the first thing you need is also the hardest to get: a straight answer about where they are. Arizona does not have one single database that lists everyone in custody. The person you are looking for could be in a county jail, a state prison, a federal facility, or immigration detention, and each of those is searched a different way. Arizona also has two features that shape almost every search here: an enormous county jail system in Maricopa County, and one of the heaviest immigration-detention footprints in the country. This guide walks you through all of it, in the order most families need, and tells you what to do when someone does not show up at all.
Start here: figure out which system is holding them
Before you search anything, answer one question, because it tells you which tool to use.
How long ago were they taken into custody, and what happened? Someone who was arrested in the last few days is almost always in the county jail for the county where the arrest happened. They stay there through booking, first appearance, and often through their entire case if it is a local charge. People do not go to "state prison" when they are arrested. They go to state prison only after they have been sentenced to more than a year and physically transferred into the custody of the state prison system, which can take weeks after sentencing.
So the rule of thumb is simple. Recently arrested, case still pending, or a short sentence: look in the county jail. Sentenced to state prison time and transferred: look in the Arizona Department of Corrections, Rehabilitation and Reentry. Federal charge: look in the federal system. Immigration hold: look in ICE custody. Most families searching for someone newly arrested waste time on the state prison site when their person is sitting in a county jail.
Maricopa County jails (where most Arizona searches start)
More people are searched for in Maricopa County than anywhere else in Arizona, because it contains Phoenix and is home to one of the largest jail systems in the United States. The Maricopa County Sheriff's Office runs this system, and it operates several separate facilities that families search by name: the 4th Avenue Jail, Lower Buckeye Jail, Towers Jail, Estrella Jail, and Durango Jail, among others. A person booked into the Maricopa system may be moved between these facilities, so the Sheriff's Office runs a single inmate lookup that covers all of them at once.
If your person was arrested anywhere in the Phoenix metro area, start with the Maricopa County inmate search rather than the state prison system. You generally need the full name, and a booking number finds the record immediately. You can also reach the specific facility through its page on InmateAid.
If the arrest happened elsewhere in Arizona, find that county's jail instead. The next largest county systems are Pima (Tucson), Pinal, Yavapai, and Mohave. Each county runs its own roster, so you search the one where the arrest happened.
Searching the Arizona state prison system (ADCRR)
The state prison system is the Arizona Department of Corrections, Rehabilitation and Reentry, abbreviated ADCRR. The "Rehabilitation and Reentry" part is a relatively recent renaming, so older guides and even some official-looking pages still call it ADOC or the Arizona Department of Corrections. It is the same system.
ADCRR holds everyone serving an Arizona state prison sentence. Its public inmate search lets you look up a person by name or by their ADC number (the state inmate identification number) and returns their current unit and basic custody information. To search, you generally need the person's first and last name, and the ADC number narrows it when the name is common.
What the ADCRR results will not tell you is anything about a county case. If your person was arrested recently and has not been sentenced and transferred, they will not be in ADCRR at all. That is normal, not a dead end. It means they are still in the county system, most often Maricopa.
Federal inmates in Arizona (BOP)
If the charge was federal, the person is in the custody of the federal Bureau of Prisons, not the state, and you search the BOP's own national inmate locator rather than any Arizona tool. It covers everyone in federal custody from 1982 to the present and searches by name or by federal register number.
Arizona holds federal facilities including the FCI Phoenix and FCI Tucson complexes and the United States Penitentiary at Tucson. A person arrested on a federal charge may first sit in a county jail under a federal contract before being moved to a federal facility, so if the BOP locator does not show them yet, check the county jail where the arrest happened.
ICE detainees in Arizona
Arizona has one of the largest immigration-detention footprints of any state, so this section matters more here than in most. ICE detainees are not criminals serving sentences; they are held in civil custody while their immigration cases are decided. Arizona's immigration detention is concentrated in large dedicated facilities in and around Eloy and Florence, in the desert between Phoenix and Tucson, most of them operated by private contractors such as CoreCivic and GEO Group under contract with ICE.
You search for an immigration detainee using the federal ICE Online Detainee Locator, which works by the detainee's A-Number (a nine-digit immigration identification number) or by their full name, country of birth, and date of birth. Because so much Arizona detention runs through a handful of large facilities, and because detainees are transferred between them and to other states, the A-Number is by far the most reliable way to track someone. If you have it, use it.
When you cannot find them anywhere
If you have searched and your person is not turning up, work through these explanations before assuming the worst.
You searched the wrong system. In Arizona this usually means searching the state prison site for someone who is actually in the Maricopa County jail. If the arrest was recent and in the Phoenix area, search Maricopa first. The booking is not complete yet. Newly arrested people can take hours to appear on a roster. Try again later the same day. They were released, transferred, or moved between systems. Someone can bond out, be moved between Maricopa facilities, or be handed from county to federal or immigration custody, and during a handoff they may briefly appear nowhere. The name does not match the record. People are booked under legal names, middle names, maiden names, or misspellings. Try variations, and search with less information rather than more. They are a minor. Juveniles are not listed in public adult locators at all, regardless of facility.
When the online tools fail, calling works. Call the jail or facility you believe is holding them, give the full name and date of birth, and ask the booking desk to confirm custody status. That is often faster than any website.
Get notified automatically: VINELink
Rather than checking rosters over and over, you can register with VINE, the free victim and family notification service Arizona participates in. It lets you look up a person's custody status and sign up for automatic alerts about changes such as transfer or release. It is the simplest way to stop refreshing a website every day, and it is especially useful in the Maricopa system, where people are frequently moved between jail facilities.
Once you have found them
Finding the person is the first step. Staying connected is the next, and it matters more than most families realize for how someone gets through their time.
The best place to start is mail. Letters and photos reach almost everyone in custody, they are the most reliable form of contact, and a person who hears from home regularly does easier time. Phone calls are the next layer, and the cost of calls dropped sharply under the federal rate caps that took effect in April 2026, so calling is more affordable now than it has been in years. You can also send money to most facilities so your person can cover phone time, commissary, and basic needs.
To set any of this up for the specific facility holding your loved one, find that facility on InmateAid and follow the instructions on its page, since the rules, the phone carrier, and the mailing address are different at every facility. In the Maricopa system this matters especially, because the mailing address and phone setup change when a person is moved between the 4th Avenue, Lower Buckeye, Towers, Estrella, and Durango facilities.

Frequently asked questions
How do I find an inmate in Arizona?
Decide which system holds them first. Recently arrested people are in a county jail, most often the Maricopa County system in the Phoenix area. People serving state prison time are in ADCRR. Federal charges mean the Bureau of Prisons, and immigration holds mean ICE.
Is there one website for all Arizona inmates?
No. Arizona has no single combined database. County jails, the state prison system, the federal Bureau of Prisons, and ICE each maintain separate searches, and you have to use the one that matches the person's situation.
How do I find someone in a Maricopa County jail?
Use the Maricopa County Sheriff's Office inmate search, which covers all of its jail facilities (4th Avenue, Lower Buckeye, Towers, Estrella, Durango) at once. You generally need the full name, and a booking number finds the record immediately.
Where is someone who was just arrested in Phoenix?
In the Maricopa County jail system, not the state prison. People only enter the state system after sentencing and transfer, which can take weeks.
What is ADCRR, and is it the same as ADOC?
ADCRR is the Arizona Department of Corrections, Rehabilitation and Reentry, the state prison system. It is the same agency older guides call ADOC; the name was changed to add "Rehabilitation and Reentry."
How do I search the Arizona state prison system?
Use the ADCRR public inmate search with the person's name or ADC number. It returns their current unit and custody information for people currently in state prison.
Why can't I find my inmate in the state system?
The most common reason is that they are not in state prison. They may be in a county jail (most often Maricopa) awaiting trial, in federal or immigration custody, or already released. Each is searched separately.
How do I find a federal inmate held in Arizona?
Use the federal Bureau of Prisons inmate locator, which is national and searches by name or federal register number. It is separate from any Arizona state tool.
How do I find someone in ICE custody in Arizona?
Use the ICE Online Detainee Locator, searching by the detainee's A-Number or by full name, country of birth, and date of birth. Arizona's immigration detention is concentrated around Eloy and Florence.
Can I get alerts when an inmate's status changes?
Yes. Register with VINE, the free notification service, to get automatic alerts about transfers and releases. It is especially useful in Maricopa, where people move between jail facilities.
What if no search finds the person?
Make sure you searched the right system (Maricopa jail, not the state prison, for recent Phoenix arrests), try again later in case booking is not complete, and try name variations. Minors are never listed publicly. If the websites fail, call the facility directly. ===================================================== PRE-PUBLISH VERIFICATION (remove before publishing - dev/editor checklist) ===================================================== State-specific items to confirm before this goes live: 1. ADCRR - confirm the current name (Arizona Department of Corrections, Rehabilitation and Reentry), the inmate search URL, and the ADC-number label. Insert the live link on "ADCRR public inmate search." 2. Maricopa County - confirm the MCSO inmate search URL and that the named facilities (4th Avenue, Lower Buckeye, Towers, Estrella, Durango) are current and active. Confirm whether Watkins should be included. Link each to its InmateAid facility page. NOTE: these are the exact pages flagged in the GSC desktop study and ticket I312 - coordinate so this guide links to them as they are fixed. 3. Other large counties - confirm Pima, Pinal, Yavapai, Mohave as the next-largest systems; link each. 4. BOP locator - confirm URL; link "Bureau of Prisons inmate locator." 5. Federal facilities in AZ - confirm FCI Phoenix, FCI Tucson, USP Tucson are current and complete. Link to InmateAid facility pages. 6. ICE in AZ - confirm the current major immigration facilities around Eloy and Florence (e.g. Eloy Detention Center, Florence, La Palma, Central Arizona Florence Correctional Complex) and operators (CoreCivic, GEO). This is a heavy-ICE state and the roster shifts; verify before naming any specific facility, then link. 7. VINE - confirm Arizona's current VINE URL and link "register with VINE." 8. Internal links - wire /prisons/arizona, the FCC 2026 calls guide (canonical path), and the Arrest Record Search affiliate with I239 honest-label language. State-specific elements that make this page unique (not a clone): - Maricopa County as the dominant search cluster gets its own dedicated section ahead of the state system, with the named MCSO facilities - directly funnels the I312 / GSC-flagged pages. - ADCRR vs ADOC naming correction (recent rebrand) with its own FAQ. - Heavy ICE footprint (Eloy/Florence corridor, private operators) treated as a major section rather than a minor note. - Maricopa inter-facility transfers woven into the connect section and VINE section (address/phone changes on move). - Free-call status: not a free-call state (caps apply, not free).
