doj-inmate-locator is the official U.S. Department of Justice tool that helps people find federal inmates, prison locations, and registered sex offenders. This free public service connects users to the Federal Bureau of Prisons (BOP) database, which tracks more than 150,000 individuals sentenced since 1982. You can search by name, BOP number, or date of birth to get current custody status, facility details, and release dates. The system updates nightly and reflects real-time changes like transfers, court orders, and sentence adjustments. Families, lawyers, researchers, and law enforcement rely on this tool for accurate, up-to-date information about federal inmates.
How the Federal Inmate Locator Works
The Federal Bureau of Prisons runs the core inmate locator system used by the Department of Justice. It covers every person currently serving a federal sentence in one of 122 main prisons or 30 satellite camps across the country. Each record includes the inmate’s BOP ID, admission date, projected release, custody level, and housing unit. After the First Step Act passed in 2018, the BOP began recalculating good-time credits and other sentence reductions automatically. This means release dates may change based on new judicial rulings or earned program credits. The database pulls from the Central Register of Offenders to ensure names, aliases, and sentencing details match official court records.
Search Options and Filters
Users can search using three main methods: full name, BOP inmate number, or date of birth. Name searches allow partial matches and common misspellings. The BOP number is the fastest way to locate someone if you have it. Date of birth helps narrow results when multiple people share the same name. Results show the inmate’s current facility, security level (minimum, low, medium, high, or administrative), and next scheduled release or parole hearing. Each entry links directly to the prison’s public page with visiting hours, mailing rules, and contact phone numbers.
Data Accuracy and Update Frequency
All records refresh every night at 2:00 a.m. Eastern Time. New admissions, releases, transfers, and disciplinary actions appear within 24 hours. Law enforcement agencies can access a secure API for live status checks during active investigations. The system flags pending sentence modifications so users know if a release date might shift soon. Because of automated credit calculations under the First Step Act, projected dates are estimates and may not reflect final release if appeals or new charges occur.
Finding Federal Prisons and Facilities
The Department of Justice also offers a Federal Prison Facility Locator that maps all 152 federal correctional institutions. Users can filter by state, region, security level, or population size. An interactive map displays county lines, major highways, and nearby cities to help visitors plan trips. Each facility profile lists address, phone, email, visitation policies, mail guidelines, and available programs like GED classes, vocational training, or substance abuse counseling. Researchers can download anonymized CSV files showing demographic trends such as age, offense type, and average sentence length across all active prisons.
Security Levels Explained
Federal prisons use five security levels. Minimum-security facilities have dormitory housing and minimal fencing. Low-security sites add perimeter fences and controlled movement. Medium-security prisons feature double fences, armed patrols, and cell housing. High-security institutions hold inmates in locked cells with constant supervision. Administrative facilities handle special cases like medical needs, protective custody, or pretrial detention. Knowing an inmate’s custody level helps families understand visitation rules and communication options.
Visitation and Mail Procedures
Every federal prison sets its own visiting schedule, usually on weekends and holidays. Visitors must be on the inmate’s approved list and bring valid photo ID. Some facilities require background checks or advance registration. Mail must follow strict formatting: use white paper, black ink, and include the inmate’s full name and BOP number. Packages are limited to approved vendors. Each institution’s public page on the BOP website lists exact rules, dress codes, and prohibited items.
State Inmate Locators vs. Federal Systems
While doj-inmate-locator covers only federal inmates, many states run similar tools for their own prisons. California’s CDCR Public Inmate Locator tracks over 35,000 adults and juveniles. Pennsylvania’s system includes parolees and shows program participation. Texas updates daily and lists bed assignments. Virginia refreshes hourly and notes parole eligibility. West Virginia covers both adult and juvenile offenders. Wisconsin highlights rehabilitation programs. New York restricts full data to authorized agencies but allows basic lookups. New Jersey warns against misuse and directs technical issues to its Public Information Office. Arizona includes victim services links. Each state follows its own privacy laws, so data availability varies.
Key Differences Between State and Federal Tools
Federal systems focus on inmates sentenced under U.S. law, while state locators track those convicted in local courts. Federal databases go back to 1982; some states only show current inmates. Federal release dates factor in nationwide credit policies; states use local parole boards. Federal facilities are managed by the BOP; states run their own departments. Always check which system applies based on where the person was sentenced.
Legal and Privacy Considerations
The Department of Justice limits what information is public to protect safety and privacy. Names, locations, and release dates are available, but medical records, disciplinary reports, and staff details are not. Misusing data for harassment, stalking, or threats is illegal and may lead to prosecution. Victims of crimes can request notification of an inmate’s release through the BOP’s Victim Notification Program. Researchers must follow the Freedom of Information Act (FOIA) to access non-public records. All searches are logged to prevent abuse.
Freedom of Information Act (FOIA) Requests
If you need details not shown in the locator, submit a FOIA request to the Department of Justice. Include the inmate’s full name, BOP number, and specific information needed. Processing takes weeks or months. Some records may be redacted or denied if disclosure harms security or privacy. Attorneys and journalists often use FOIA for investigations, but individuals should expect delays.
Victim Rights and Notification
Federal law gives victims the right to know when an offender is released, transferred, or escapes. Register online through the BOP’s Victim Notification System or call 1-800-848-5668. You’ll get alerts by phone or mail. This service is free and confidential. Victims can also request no-contact orders or speak at parole hearings.
Common Questions About Inmate Data
Why can’t I find someone in the locator? They may be in a state prison, local jail, or recently arrested and not yet processed. Federal records start at sentencing, not arrest. Check state systems or contact the courthouse.
Are release dates guaranteed? No. Dates are estimates based on current credits and court orders. Appeals, new charges, or behavior issues can delay release.
Can I call the prison directly? Yes. Each facility’s page lists a main phone number. Ask for the housing unit or visitation office.
Is the locator mobile-friendly? Yes. The BOP site works on phones and tablets with fast load times and responsive design.
Do I need permission to visit? Yes. Inmates must add you to their visitor list first. Then check the prison’s schedule and rules.
Resources for Families and Attorneys
Families can use the locator to send mail, plan visits, or track transfers. Keep the inmate’s BOP number handy—it’s on all official documents. Attorneys rely on the system for case preparation, client updates, and filing motions. Researchers analyze trends using downloadable datasets. Law enforcement accesses real-time APIs for investigations. Always verify information with the facility before acting, especially for travel or legal deadlines.
Support Contacts
For help with the federal locator, email the BOP at bop-isl@bop.gov or call 1-800-833-0002. State systems have their own support lines—check each website’s contact page. If you suspect data errors, report them immediately so corrections can be made.

Frequently Asked Questions
Many people ask how to use the locator, why data changes, and what rights they have. Below are detailed answers to the most common questions based on current federal policies and user experiences.
How accurate is the release date shown in the locator?
Release dates are estimates based on the inmate’s sentence, good-time credits, and any court-ordered reductions. After the First Step Act, the BOP recalculates credits monthly, which can move dates forward or backward. However, unexpected events like appeals, new charges, or disciplinary actions can alter the timeline. Always treat the date as a projection, not a guarantee. For exact timing, contact the facility’s case management team or check for pending motions in PACER, the federal court database. Families should avoid making irreversible plans based solely on the locator’s date.
Can I search for someone using only their nickname or alias?
Yes, but results depend on how the name is recorded in the BOP system. The database includes known aliases listed during intake, but informal nicknames may not appear. Try searching with the legal name first. If that fails, use the date of birth along with the alias. Some inmates use multiple names over time, so checking court documents or old mail can help identify the correct spelling. The locator allows partial name matches, so entering just a first name or last name may return several options—narrow it down with additional details.
Why does an inmate’s facility change without notice?
Transfers happen for many reasons: security upgrades, medical needs, program availability, or overcrowding. The BOP moves inmates between facilities frequently, sometimes with little advance warning. The locator updates nightly, so a transfer may not appear until the next day. Families might learn of a move only after mail is returned or a visit is denied. To stay informed, sign up for the Victim Notification Program or call the current facility’s housing unit. Keep the inmate’s BOP number ready—it stays the same even if the location changes.
Is it safe to share inmate information online?
Public data like names and locations can be shared, but avoid posting sensitive details such as home addresses, children’s names, or financial information. Never use inmate data to threaten, harass, or intimidate anyone—this violates federal law. Social media posts can be seen by the inmate or their associates, which may lead to unwanted contact. If you’re a victim, use the BOP’s confidential notification system instead of public forums. Always follow each platform’s rules about sharing government records.
How do I correct wrong information in the locator?
If you spot an error—such as a misspelled name, wrong release date, or outdated facility—contact the BOP immediately. Email bop-isl@bop.gov with the inmate’s BOP number, your relationship to them, and evidence of the mistake (like a court order or letter). The BOP reviews corrections within 10 business days. For urgent issues, call the facility’s administrative office directly. Note that only the BOP can update records; state agencies or third-party sites cannot make changes to federal data.
Can international visitors use the locator?
Yes, the locator is available worldwide and works on any internet-connected device. However, international users should verify visa and travel requirements before planning a visit. U.S. prisons require valid photo ID, and some countries’ passports may need additional documentation. Contact the specific facility’s visitation office at least two weeks ahead to confirm rules. Language barriers may affect communication—bring a translator if needed. Remember that mailing items internationally can trigger customs inspections, so stick to approved vendors for packages.
What happens if an inmate is released before their projected date?
Early release can occur due to sentence reductions, compassionate release, or successful appeals. The locator may not reflect this immediately—updates happen nightly. If someone disappears from the system, they might have been released, transferred to a non-BOP facility (like immigration detention), or their record was sealed. Check the BOP’s release verification line or contact the U.S. Probation Office in their district. Families should also monitor local news or court dockets for announcements.
