You can run a free background check using public records by combining searches across several government databases: a national sex offender registry, federal court records through PACER, federal exclusion lists, and the court, licensing, and property record sites maintained by the state and county where the person has lived. No single free site covers everything, so a thorough check means running the same name through several systems and stitching the results together.
Gather Identifying Details First
A name by itself rarely produces useful results, especially for common surnames. Before opening any database, collect the person’s full legal name including middle name, any former names or aliases, date of birth, and a rough list of the counties where they’ve lived over the past seven to ten years. Most criminal and civil records sit in county systems, so knowing the geography tells you which local databases to search. Without it, you’re guessing, and guessing with a common name returns hundreds of irrelevant hits.
Date of birth is the single best filter. Two people named Michael Johnson in the same county is common; two with identical birthdays is rare. If you’re checking your own background, you already have everything. If you’re looking into someone else, old correspondence, social media, and shared contacts can fill the gaps.
Free Federal Databases to Search
A few federal systems are genuinely free and cover the whole country. Start here before moving to state and county sites.
National Sex Offender Public Website
The Dru Sjodin National Sex Offender Public Website, run by the Department of Justice, searches sex offender registries across all 50 states, D.C., U.S. territories, and tribal lands in a single query. It’s free, no account required, and you can search by name or location.1Dru Sjodin National Sex Offender Public Website. Home This is one of the rare databases where one search actually covers every jurisdiction.
PACER for Federal Court Records
PACER provides electronic access to federal court records: bankruptcy filings, federal criminal cases, and civil lawsuits filed in federal district courts. It’s not entirely free. Access runs 10 cents per page, capped at the equivalent of 30 pages per document, but no fee actually accrues until your account passes $30 in a quarterly billing cycle. Light users pay nothing. Judicial opinions are always free.2United States Courts. Electronic Public Access Fee Schedule For a quick check on whether someone has a federal bankruptcy or federal case, the quarterly threshold makes PACER effectively free.
OIG Exclusion List
The Office of Inspector General’s List of Excluded Individuals and Entities is a free searchable database of people barred from federal healthcare programs like Medicare and Medicaid.3Office of Inspector General. LEIE Database and Supplement Downloads Anyone hiring in healthcare should check it; employing an excluded individual can trigger significant penalties for the employer.
SAM.gov Exclusions
The System for Award Management lists individuals and companies debarred or excluded from federal contracts and certain government benefits. The search is free and public. It matters most when you’re vetting someone for a government contracting role or a business partnership.
State and County Court Records
Most criminal and civil case information lives at the county level, with the court where the case was heard. Most state court systems now offer free online case search tools, but quality varies sharply. Some states run a statewide portal that pulls from every county. Others make you search one county at a time. A few still require in-person requests for anything beyond bare-bones case data.
To find the right site, search for the county’s clerk of court or the state’s judicial branch website and look for a “case search” or “records inquiry” link. A typical result shows the case number, the charges or claims, filing dates, and the disposition (how the case ended). Viewing this basic information is usually free. Certified copies of documents usually cost a small fee per page.
State criminal records repositories, often housed inside the state police or department of public safety, may offer a separate name-based search for a small fee. These aggregate reports from courts across the state into one record, which is more efficient than checking each county in turn if the person has moved around.
Other Public Records That Fill in the Picture
Beyond criminal and civil cases, several other categories of public records help round out a background check.
County assessor and recorder offices maintain records of property ownership, transfers, tax assessments, and liens, and many counties offer free online search tools. These records show whether someone owns real estate, whether there are tax liens on that property, and the history of ownership transfers.
State licensing boards maintain databases showing whether someone holds an active license in fields like nursing, law, real estate, or construction. Most are searchable online at no cost and display the license status along with any disciplinary actions. Go to the state licensing board directly rather than through a third-party aggregator, which may show stale data.
Military service records become fully open to the public 62 years after the service member separates. For more recent records, the Freedom of Information Act and the Privacy Act limit what can be released without the veteran’s consent.4National Archives. Request Military Service Records You can verify limited details of recent service, but you won’t get a full file without authorization.
Running a Check on Yourself
If you want to see what a landlord or employer would find, you have access to resources that aren’t available when researching someone else.
Your Credit Report
Federal law entitles you to one free credit report every 12 months from each of the three major credit bureaus: Equifax, Experian, and TransUnion. The only authorized site for these free reports is AnnualCreditReport.com.5Federal Trade Commission. Free Credit Reports Your report shows open accounts, payment history, collections, and public records like bankruptcies. Employers who order background checks through consumer reporting agencies often pull credit information as part of the report, so seeing yours first lets you catch errors before they cost you a job or an apartment.
Your FBI Identity History Summary
You can request your own Identity History Summary from the FBI, which shows any criminal history the bureau has on file about you. The request requires fingerprints and costs $18, with fee waivers available if you can’t afford it.6Federal Bureau of Investigation. Identity History Summary Checks Frequently Asked Questions It’s the closest thing to a national criminal records check. State and county databases only see their own turf; the FBI aggregates reports from agencies across the country. The bureau’s underlying database is not publicly searchable, so an FBI check on someone else is not something you can run for free or otherwise.
What You Won’t Find for Free
Some information is simply not visible to public searches, and it’s important to know what you’re missing so you don’t misread a clean search as a complete one.
Federal courts require redaction of Social Security numbers, names of minor children, financial account numbers, and dates of birth from electronic case filings. In criminal cases, home addresses are also redacted.7United States Courts. Privacy Policy for Electronic Case Files State courts have their own redaction rules, generally along the same lines.
Sealed and expunged records don’t appear in any public database. When a court seals a case, the online systems no longer show it. Some states seal certain records automatically after a waiting period; others require a petition. If a search turns up nothing, that doesn’t guarantee nothing happened. The record may be sealed.
When a Free Search Isn’t Legally Enough
There’s a legal line between looking up public records for personal knowledge and using background information to make decisions about someone’s employment, housing, credit, or insurance. The Fair Credit Reporting Act draws that line.
Under the FCRA, background reports used for these “permissible purposes” must come from a consumer reporting agency, not a do-it-yourself search.8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports An employer or landlord who uses such a report to reject an applicant must follow a two-step adverse action process: give the applicant a copy of the report and a summary of their rights before making the final decision, then send a formal adverse action notice afterward identifying the reporting agency and explaining the right to dispute the information.9Federal Trade Commission. Using Consumer Reports: What Employers Need to Know The Consumer Financial Protection Bureau now holds FCRA rulemaking authority under the Dodd-Frank Act, and the Federal Trade Commission retains enforcement.10Federal Trade Commission. Fair Credit Reporting Act
A DIY search through court websites is legal for personal knowledge. The trouble starts when an employer runs their own court search, finds a conviction, and rejects an applicant without providing the required notices. Willful violations carry statutory damages between $100 and $1,000 per violation, plus potential punitive damages.11Office of the Law Revision Counsel. 15 USC 1681n – Civil Liability for Willful Noncompliance Even negligent violations can result in actual damages and attorney’s fees.12Office of the Law Revision Counsel. 15 USC 1681o – Civil Liability for Negligent Noncompliance
For personal vetting, free searches are fine. For formal decisions about employment, housing, or credit, go through a compliant consumer reporting agency and follow the notice requirements.
