To find out if someone was arrested, start with a phone call to the county jail or local police non-emergency line where you think the arrest happened, then check that agency’s online jail roster. For federal arrests, use the Bureau of Prisons Inmate Locator. If those come up empty or you need ongoing updates, VINE alerts, court docket searches, and public records requests fill the gaps. Have the person’s full legal name and, ideally, date of birth before you start; every search runs faster with both.
Call the Jail or Police Department
A phone call is the fastest way to confirm a recent arrest. Every county jail and city detention center keeps a log of people currently in custody, and staff can usually tell you over the phone whether a specific person is booked there. Call the non-emergency line for the local police department or the county sheriff’s office in the area where you believe the arrest happened. You don’t need to explain your relationship to the person or your reason for asking. Booking information is public in the vast majority of jurisdictions.
Have the person’s full legal name ready along with a date of birth if you know it. Nicknames and partial names slow the process and increase the chance of a wrong match. If the facility can’t find anyone under that name, ask whether the person might have been transferred elsewhere or released on bail. Recent arrests sometimes take a few hours to appear in the system, so if you’re checking within the first hour or two after a suspected arrest, expect to call back.
Check the Online Jail Roster
Many county jails publish their booking logs online, sometimes called a “jail roster” or “who’s in custody” list. These pages are updated throughout the day and typically show the person’s name, booking date, charges, and bail amount. A web search for the county name plus “jail roster” or “inmate search” will usually lead you to the right page.
State departments of corrections run their own searchable databases for people in state prison. You can search by name, date of birth, or booking number and see the current location, charges, booking date, and expected release date. Larger jurisdictions update in near-real time. Smaller facilities may lag by a day or more, and each database only covers its own facilities. If you don’t know where someone was arrested, you may need to check multiple counties. Starting with the county where the person lives or was last seen is usually the most productive first move.
Use the Federal Bureau of Prisons Inmate Locator
For federal arrests and inmates in federal prison, the Bureau of Prisons runs a free Inmate Locator that covers everyone incarcerated in the federal system from 1982 to the present. You can search by name or registration number, and results include the person’s age, facility location, and projected release date.1Federal Bureau of Prisons. Inmate Locator
If the search returns “Released” or “Not in BOP Custody” with no facility listed, the person is no longer in federal custody but may still be on supervised release or held by a state or local system. The federal locator won’t show anyone in a state prison or county jail, so a “no match” result there doesn’t mean the person hasn’t been arrested.
Sign Up for VINE Notifications
If you need to track someone’s custody status over time rather than answer a one-time question, the Victim Information and Notification Everyday system, known as VINE, is a free nationwide service that sends automatic alerts when an offender’s custody status changes. You can register for notifications by phone, email, text message, or through the VINELink mobile app, and the system operates around the clock.2Office for Victims of Crime. Victim Notification
If someone is arrested, released on bail, transferred between facilities, or escapes custody, VINE sends an alert. Not every county participates, but coverage is extensive. You can also search VINELink’s online database for free without registering for notifications.
Search Court Dockets
Court records pick up where jail records leave off. Once charges are filed, the case enters the court docket system, which tracks everything from arraignment through sentencing or dismissal. Docket entries show the charges, hearing dates, plea information, and case outcome. This is the tool to use when you want to know what happened after an arrest rather than just confirm that one occurred.
Many state and county courts have digitized their dockets, and a growing number offer free online searches by name or case number. Access policies vary. Some courts let anyone search for free, while others charge for detailed records or certified copies.
Federal court records are available through PACER, the Public Access to Court Electronic Records system. PACER charges ten cents per page with a cap of three dollars per document. If your account accrues thirty dollars or less in a given quarter, the fees are waived entirely, which makes casual searches effectively free.3PACER.

File a Public Records Request
When phone calls and online tools come up empty, a formal public records request can shake loose arrest information that isn’t available through self-service channels. Every state has an open records or “sunshine” law that gives the public a right to request government-held documents, including arrest reports and booking records. The request doesn’t have to follow a specific form. A written letter or email identifying the records you want is enough in most places.
Include as much detail as you can: the person’s full name, approximate date of arrest, and the agency that made the arrest. The more specific you are, the faster the agency can locate the records. Response deadlines vary by state, ranging from as few as three business days to twenty or more, and roughly a quarter of states have no fixed deadline at all. Processing fees for paper copies are common but usually modest, a few dollars for a standard arrest report.
Federal Arrests and FOIA
If the arrest involved a federal agency like the FBI, DEA, or U.S. Marshals, file a request under the Freedom of Information Act instead. FOIA requests must be in writing and should reasonably describe the records you want. Most federal agencies accept requests electronically by web form or email. The process is decentralized, so direct your request to the specific agency that made the arrest. There’s no single clearinghouse.4FOIA.gov. How to Make a FOIA Request
If you’re requesting your own arrest records, expect to verify your identity with a signed, sworn statement. Federal agencies have twenty working days to respond, though complex requests can take much longer. Agencies won’t create new records or do research on your behalf. They only search for and produce existing documents.
Be Careful With Commercial Background Check Sites
Dozens of websites offer instant background checks and arrest record searches for a fee, and they often dominate the first page of search results. These services aggregate data from public records databases and can be a convenient starting point, but their accuracy is poor. A University of Maryland study found that more than half of participants had at least one false positive on their background checks, meaning the report included charges that didn’t belong to them, and about ninety percent had at least one false negative, where real charges were missing entirely.
The core problem is that commercial services match records using names, aliases, and birth dates rather than fingerprints. That approach lumps together people who share similar identifying information. If you use one of these sites and find an arrest record, treat it as a lead to verify through official channels, not as confirmed fact.
If You Find Nothing
An empty result doesn’t always mean the arrest never happened. Records involving ongoing investigations, juvenile proceedings, and cases under seal won’t appear in any public search. Virtually every state now allows people to petition for the sealing or expungement of arrest records under certain circumstances, and juvenile arrest records generally receive stronger protections and are often sealed automatically once the person turns eighteen. If you need access to sealed records for a legitimate legal purpose, a court order is typically required, and an attorney is the most reliable path when the stakes are high.
