Can You Find an Inmate Online?
Yes — finding an inmate in the United States is easier than most people think. Every state maintains a public Department of Corrections (DOC) inmate database, the federal government has the Bureau of Prisons (BOP) locator, and private services like TruthFinder can search criminal records across all 50 states in seconds.
The key is knowing which tool to use based on your situation. This guide walks through every method, starting with the fastest.
5 Methods to Find an Inmate
Search Criminal Records (Fastest — All 50 States)
TruthFinder searches public criminal records from every state simultaneously, including arrest history, court records, and current incarceration status. Best when you don't know which state the person is in.
Search Records on TruthFinder (Sponsored) →State DOC Inmate Locator (Free — If You Know the State)
Every state provides a free official inmate locator on their Department of Corrections website. These databases show current facility, sentence length, and anticipated release date for state inmates.
View All 50 State DOC Links →Federal BOP Inmate Locator (Free — For Federal Prisons)
The Bureau of Prisons maintains a free locator at bop.gov for anyone serving time in a federal prison. You can search by name, age, or BOP register number.
Search Federal BOP Locator →County Jail Roster (For Recently Arrested)
Someone recently arrested may be in a county jail before entering the state system. Check the county sheriff's website for the county where the arrest occurred — most publish daily updated inmate rosters.
Search County Jails by State →JailData Facility Search (Find the Facility First)
If you believe you know which facility someone is in, search our database of 14,000+ prisons and jails. Every listing links directly to that facility's official inmate search page.

Each state's Department of Corrections maintains a free public inmate database. Here's how to use them effectively:
- Go to the state DOC website — Use our complete directory of all 50 state DOC locators.
- Enter the person's full legal name — Use their legal name, not a nickname. Middle names or initials can help narrow results.
- Add additional details if available — Date of birth, inmate ID number, or approximate age dramatically improves accuracy.
- Review results carefully — Common names may return multiple results. Cross-reference age, location, and any known offenses.
- Note the facility information — The DOC record will show the current facility, mailing address, and sometimes phone information.
Finding Someone in Federal Prison
Federal inmates (those convicted of federal crimes like drug trafficking, bank robbery, or white-collar crimes) are housed in Bureau of Prisons facilities rather than state prisons.
The BOP Inmate Locator at bop.gov is free and shows:
- Current facility name and location
- Inmate's register number
- Age and race
- Release date (projected)
- Whether they are currently in custody or released
Finding Someone Recently Arrested
If someone was recently arrested, they may not yet appear in state DOC systems — the process of transferring from county jail to state prison can take days or weeks after sentencing.
Check the County Jail Roster
Most county sheriff's offices publish real-time inmate rosters online. Search for the county where the arrest occurred and look for an "Inmate Search" or "Jail Roster" on the sheriff's website.
Search Arrest Records
Criminal records searches like TruthFinder often capture recent arrest data before it appears in official DOC databases. This can be the fastest way to confirm a recent arrest.
Tips for a Successful Inmate Search
- Try variations of the name — Nicknames, middle names as first names, or slight spelling variations can help.
- Know whether it's state or federal — Federal crimes use federal prisons; state crimes use state prisons. When in doubt, check both.
- Have a date of birth ready — It's the single most useful piece of identifying information after a name.
- Check multiple states — Someone could be transferred to another state under an interstate corrections agreement.
- Results can lag — Official databases may take 24-48 hours to update after someone is admitted or transferred.
Once You Find the Inmate
After locating the facility, you can:
- Search the facility on JailData for visiting hours, mailing address, and inmate services
- Send mail using the correct inmate name + ID format
- Schedule a visit through the facility's official visitation registration
- Send money via the facility's approved commissary service
- Send books via Amazon directly to the facility
Frequently Asked Questions
The fastest method is to search criminal records through TruthFinder, which covers all 50 states simultaneously. For free official results, use your state's Department of Corrections inmate locator. For recently arrested individuals, check the county sheriff's website where the arrest occurred.
Yes — official state DOC inmate locators and the federal BOP locator at bop.gov are completely free. TruthFinder is a paid service that provides more comprehensive criminal history data including arrest records, court documents, and historical incarceration data beyond just current status.
Online criminal records searches return results in seconds. Official DOC database searches are also real-time for currently incarcerated individuals. Note that databases may take 24-48 hours to update after someone is newly admitted or transferred between facilities.
At minimum you need the person's first and last name. Having the state where they're incarcerated, date of birth, or inmate ID number significantly narrows results. For common names, more identifying information produces better results.
Recently arrested individuals appear on county jail rosters before entering state DOC systems. Check the county sheriff website for the county where the arrest occurred. Criminal records searches like TruthFinder also index recent arrest data.
Private prisons house inmates on behalf of the government — the inmate will still appear in the relevant state or federal DOC database. Search the state DOC or BOP as normal.
