A criminal background check works by having a screening company gather records tied to your identity from county courthouses, state criminal record repositories, and sometimes federal databases, then compile them into a report for an employer, landlord, or licensing body. How do criminal background checks work in practice? A screener starts with your name, date of birth, and Social Security number, traces the addresses you’ve lived at, searches court records in those places plus any relevant state and federal sources, and returns a report listing convictions, and in some cases pending cases, active warrants, and recent arrests. Federal law, mainly the Fair Credit Reporting Act, controls what can be reported, who can order the report, and what has to happen before it’s used against you.
Where the Records Come From
Criminal records start at the county level. When someone is arrested, charged, or convicted, the local courthouse creates and holds the official file. County clerks maintain detailed records of proceedings, charges, and dispositions, and in many places, older paper files have never been digitized. A check that only queries electronic databases can miss records sitting on paper in a county clerk’s office.
As cases move forward, the information typically flows from the county to a state-level central repository run by the state police or a state bureau of investigation. These repositories consolidate records from counties across the state, but the upload isn’t always immediate. If a county clerk hasn’t yet transmitted a recent arrest or disposition, that record effectively exists in only one place.
At the federal level, the National Crime Information Center, managed by the FBI, aggregates data from local, state, tribal, and federal criminal justice agencies.{1eCFR. 28 CFR Part 20 – Criminal Justice Information Systems The NCIC tracks offenses that cross state lines and maintains records on active warrants, stolen property, and missing persons. Direct access is restricted to authorized criminal justice personnel and specific government agencies.{2Federal Bureau of Investigation. Privacy Impact Assessment – National Crime Information Center Private employers and landlords can’t query it. When they run a check, they’re using commercial screening companies that search court records and state repositories.
Two consequences follow. First, the completeness of any check depends on which counties and states the screener actually searches. Second, an employer that only pays for a single-state database search may miss records in counties where you actually lived.
Name-Based vs. Fingerprint-Based Searches
Name-based searches are the standard method for most employment and rental screenings. The screening company uses identifiers like your full name, date of birth, and Social Security number to locate matching records in court databases and state repositories. Results usually come back within one to three business days, and the searches are inexpensive.
The tradeoff is accuracy. Two people can share the same name and a similar date of birth, so name-based searches occasionally produce false positives where another person’s record gets attributed to you. To reduce that risk, careful screeners run a Social Security number trace first to confirm your address history over the past several years, then search court records in every county where you’ve lived. Skipping that step is where cheaper background checks fall short.
Fingerprint-based checks use biometrics to match you against digitized records held by the FBI and state identification bureaus. Because fingerprints are unique, this method removes the false-positive problem. The FBI requires fingerprint submissions to go through the state’s central record repository, so you’re checked at both the state and federal level in a single process.{3Federal Bureau of Investigation. National Fingerprint Based Background Checks Steps for Success Fingerprint checks are standard for security clearances, professional licensing in fields like healthcare and law, and roles working with children or other vulnerable populations. You can request your own FBI identity history summary for $18, either electronically or by mail.{4Federal Bureau of Investigation. Identity History Summary Checks Frequently Asked Questions Results generally take longer than name-based searches because the prints run through both state and federal databases.
What Shows Up on the Report
The core of a criminal history report is conviction records, both felonies and misdemeanors. Felonies are the more serious category and generally carry potential sentences of more than one year of incarceration; misdemeanors are less severe offenses typically punishable by fines, shorter jail stays, or both.{5Office of the Law Revision Counsel. 15 USC 1681 – Congressional Findings and Statement of Purpose Each entry typically lists the date of the offense, the charge, and the final outcome.
Beyond convictions, reports may include pending cases that haven’t reached a verdict, active warrants, and in some situations, arrest records that didn’t lead to a conviction. If a case was dismissed or you were acquitted, the report should reflect that outcome, though the fact of the arrest may still appear within the allowed reporting window.
Convictions Have No Federal Time Limit
Federal law places no time limit on reporting criminal convictions. A felony conviction from 20 years ago can still appear on a background check. Some states impose their own limits, but the federal baseline allows convictions to be reported indefinitely.
Arrests Without a Conviction: the Seven-Year Rule
An arrest that didn’t result in a conviction, whether it was dismissed, dropped, or ended in acquittal, cannot be reported after seven years from the date of the arrest.{6Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports The Consumer Financial Protection Bureau has confirmed that because reporting a dismissal would necessarily reveal the underlying arrest, dismissals also fall within this seven-year restriction.{7Consumer Financial Protection Bureau. Fair Credit Reporting Background Screening
One important exception: if the position pays $75,000 or more per year, the seven-year cap on non-conviction data doesn’t apply, and older records can be included. Higher-earning applicants may see a more extensive history than someone applying for a lower-paying role. Many states have their own reporting restrictions that can be stricter than the federal baseline, so which rules apply depends on where the check is conducted.
Sealed and Expunged Records
Records a court has ordered sealed or expunged are supposed to be excluded from standard background reports. A screening company that reports expunged information risks violating federal accuracy requirements. In practice, expungement depends on courts updating their records and screening companies catching the change. Delays happen, and outdated records sometimes surface anyway.
Who Is Allowed to Run One on You
Not just anyone can pull your criminal history from a screening company. Under federal law, a consumer reporting agency can only furnish a report when the requester has a “permissible purpose.” The most common permissible purposes are evaluating you for credit, employment, insurance, or a business transaction you initiated, such as a rental application.{8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports A curious neighbor or an ex-partner has no legal basis to order your report.
The permissible purpose rule applies to consumer reports produced by screening companies. It doesn’t prevent someone from searching publicly available court records on their own. Most county courts maintain online dockets that anyone can browse. Those raw records lack the verification, formatting, and compliance safeguards a formal consumer report provides.
Consent, Notice, and Adverse Action
The FCRA, codified starting at 15 U.S.C. ยง 1681, is the primary federal law governing how background checks are conducted and how your information is handled.{5Office of the Law Revision Counsel. 15 USC 1681 – Congressional Findings and Statement of Purpose It applies whenever a third-party screening company produces the report.
Before the Search
For employment checks, an employer must give you a written disclosure, on a standalone document, stating that a background check may be obtained, and you must authorize the check in writing.{8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports The disclosure can’t be buried in the fine print of a job application; it has to be a separate document that serves no other purpose. For housing and other non-employment purposes, the FCRA still requires a permissible purpose but doesn’t impose the same standalone-disclosure requirement. Landlords typically obtain consent through the rental application itself, with the legal standard being that the screening relates to a transaction you initiated.{9Federal Trade Commission. What Tenant Background Screening Companies Need to Know About the Fair Credit Reporting Act
If the Report Is Used Against You
If an employer or landlord decides not to move forward with you based partly or entirely on your background check, federal law requires a two-step adverse action process.
First, they have to send a pre-adverse action notice that includes a copy of the report they relied on and a copy of the document titled “A Summary of Your Rights Under the Fair Credit Reporting Act.”{10Federal Trade Commission. Using Consumer Reports What Employers Need to Know The point is to give you time to review the report and flag errors before the decision is locked in. Most employers wait about five business days before proceeding, though the FCRA doesn’t specify an exact waiting period.
Second, if they move forward with the rejection, they must send a final adverse action notice. That notice has to include the name, address, and phone number of the screening company that produced the report, a statement that the screening company didn’t make the decision, and information about your right to a free copy of the report and to dispute its accuracy within 60 days.{11Office of the Law Revision Counsel. 15 USC 1681m – Requirements on Users of Consumer Reports
Free Copies of Your Report
You’re entitled to a free copy of your background report in several situations: when someone takes adverse action against you based on the report, when you’re a victim of identity theft, when your file contains fraud-related inaccuracies, when you’re receiving public assistance, or when you’re unemployed and expect to apply for work within 60 days. Beyond those triggers, every consumer can request one free disclosure per year from each nationwide consumer reporting agency.
How Long a Background Check Takes
Turnaround depends on the type of search and where the records sit. A standard name-based criminal check through a commercial screening company usually returns results in one to three business days. Multi-county or multi-state searches take longer, especially where jurisdictions still rely on manual courthouse searches.
Fingerprint-based checks through the FBI generally take longer because the prints run through both the state repository and the federal level, and delays are common when prints are rejected for image quality and have to be resubmitted. For applicants, the most frequent cause of a slow check is having lived in multiple jurisdictions. Each county search adds time, and some rural courthouses with limited staff can take a week or more to respond to a records request.
If the Report Contains Errors
Errors on background checks are more common than most people realize. Records get attached to the wrong person because of a shared name, expunged convictions still show up because the court’s update hasn’t propagated, and a dismissed charge sometimes appears as a conviction because the screening company pulled incomplete data.
Screening companies are required to follow reasonable procedures to ensure the maximum possible accuracy of the information they report. If you find an error, you have the right to dispute it directly with the reporting agency. Once you file a dispute, the agency generally has 30 days to investigate and correct any inaccuracies.{12Office of the Law Revision Counsel. 15 USC 1681i – Procedure in Case of Disputed Accuracy If the agency can’t verify the information within that window, it must be removed from your file.
If you receive a pre-adverse action notice and the report is wrong, move fast. Contact the screening company named in the notice and file a formal dispute. You can also contact the original source of the error, whether that’s a county court or a state repository, and ask for a correction at that level so the mistake doesn’t resurface on future checks. If you expect to be screened soon, requesting your own FBI identity history summary for $18 is a practical way to see what’s in your federal file and fix problems before an employer or landlord finds them.{4Federal Bureau of Investigation.
