In most cases, yes — police can tell you if someone is in custody, because once a person has been arrested and booked, their name, charges, and holding facility become part of the public record. You can usually confirm custody by calling the arresting agency’s non-emergency line, searching an online jail roster, or using a federal locator tool. The main exceptions are active investigations, juvenile cases, and records a court has sealed.
How to Confirm Someone Is in Custody
The right starting point depends on who you think made the arrest.
Local Police and County Jails
Call the non-emergency line of the police department or sheriff’s office in the area where the arrest likely happened. Have the person’s full legal name and date of birth ready. Jail staff can usually confirm whether someone is currently booked, what they’re charged with, and where they’re being held. Many county jails and sheriff’s offices also publish searchable inmate rosters online, often updated within hours of booking. Those rosters typically return booking date, charges, and bail amount when you search by name.
If the jail roster comes up empty, try the county courthouse. Court clerks maintain records of criminal filings and can tell you whether charges have been filed, even if the jail’s system hasn’t caught up. In the first several hours after an arrest, records are still moving through the pipeline, so a blank result doesn’t always mean no arrest happened.
Federal Custody
For someone held in a federal facility, the Bureau of Prisons runs an online Inmate Locator covering anyone incarcerated in the federal system from 1982 to the present. You can search by name or by BOP register number, FBI number, or INS number, and results show the facility where the person is held. Release dates displayed there may not be fully current because of ongoing sentence recalculations under the First Step Act.1Federal Bureau of Prisons. Inmate Locator
A “Released” or “Not in BOP Custody” result isn’t the same as being free. The person could be in state custody, on supervised release, or held by a different agency.
Immigration Detention
If you think U.S. Immigration and Customs Enforcement detained the person, the Online Detainee Locator System can help. You’ll need their name, country of birth, and date of birth, or the 8- or 9-digit A-number from any Department of Homeland Security correspondence.2USAGov. Locate Someone Being Detained by ICE for Immigration Violation or Deportation If you already know which facility is holding them, calling that detention center directly is often faster.
Why This Information Is Public
Booking records sit in an unusual spot in privacy law. The federal Freedom of Information Act and equivalent state open records laws create a general presumption of transparency around government activity, and basic booking data falls on the public side of that line. Name, charges, date and location of arrest, and holding facility are all standard public information once booking is complete.
Federal law still lets agencies withhold law enforcement records when disclosure “could reasonably be expected to interfere with enforcement proceedings.”3Office of the Law Revision Counsel. United States Code Title 5 Section 552 – Public Information; Agency Rules, Opinions, Orders, Records, and Proceedings The default is disclosure; active cases can override it temporarily.
Getting Alerts About Custody Changes
If you need to track when someone’s status changes rather than just confirm a booking, VINE (Victim Information and Notification Everyday) is built for that. It runs in 48 states and covers roughly 2,900 facilities, sending real-time alerts when an inmate is released, transferred, or escapes.4VINELink. VINE
You can register for notifications by text, email, phone call, or through the VINELink app. There’s also 24/7 toll-free support at 1-866-277-7477 with live operators in over 200 languages.4VINELink. VINE The service was built for crime victims but is open to any member of the public. Personal information you submit stays confidential and is used only for notifications.
When Police Won’t Confirm Custody
There are situations where an agency will decline to say whether someone is being held, even to a close family member.
Active Investigations
Police can withhold custody information when releasing it might compromise an ongoing case. If confirming an arrest could tip off other suspects, endanger witnesses, or give someone a chance to destroy evidence, agencies have legal authority to stay quiet. Federal FOIA law specifically exempts law enforcement records whose disclosure could interfere with enforcement proceedings or endanger physical safety.5FOIA.gov. Freedom of Information Act – Frequently Asked Questions State open records laws contain similar exemptions. This is the most common reason for a “we can’t confirm or deny” response.
Juvenile Cases
Records involving minors are treated very differently. Federal law requires that juvenile delinquency records “be safeguarded from disclosure to unauthorized persons” during and after proceedings. Unless a juvenile is prosecuted as an adult, neither their name nor photograph can be made public in connection with the case. Records are released only to a narrow list of authorized recipients, including other courts, law enforcement investigating a crime, treatment facilities, national security agencies, and victims of the juvenile’s offense.6Office of the Law Revision Counsel. United States Code Title 18 Section 5038 – Use of Juvenile Records
Courts must inform the juvenile and their parent or guardian, in plain language, about rights related to the record. So a parent or legal guardian gets notified directly. A neighbor, teacher, or more distant relative will generally be turned away.
Sealed and Restricted Cases
A judge can issue an order restricting release of custody or case information. Sealed indictments, protective orders in domestic violence matters, and cases involving confidential informants all fall under this. Arrests that never led to charges, and charges that were later dismissed, may also carry restricted disclosure in many jurisdictions to protect the individual’s privacy.
What Information You’ll Actually Get
When you reach the right agency, they’ll typically confirm:
- Whether the person is currently in custody and at which facility
- The charges listed at booking, though these can change as the case develops
- Bail amount and any conditions, if bail has been set
- Which department made the arrest, which matters if the person has been transferred
- Upcoming court dates, particularly after the initial appearance
What you won’t get is investigative detail. Police don’t share evidence, witness statements, the substance of interrogations, or anything beyond the booking record. They also won’t release medical information about the person in custody or details about others involved in the same case. Confirmation is limited to where someone is and what they’re formally charged with.
The Person in Custody Can Usually Call You
One thing people trying to track someone down often overlook: the arrested person can typically call out. Most states guarantee at least some right to phone calls after arrest, though the strength of those protections varies widely. Roughly a third of states provide strong statutory protections for an arrested person’s right to communicate; about a fifth offer no clear protections at all.
At the federal level, the Bureau of Prisons requires wardens to allow inmates at least one phone call per month, with collect calls available for those without funds. New arrivals to a facility specifically qualify for collect call privileges as “good cause.”7Federal Bureau of Prisons. Program Statement 5264.08, Inmate Telephone Regulations Most local jails allow calls shortly after booking, though calls are almost always collect or require a prepaid account, and timing can stretch depending on how busy the facility is.
If you haven’t heard from someone you expected to be arrested, that alone doesn’t mean they’re being held. Booking can take hours, phones may not be immediately available, and the person may not have your number memorized.
