The main types of criminal background checks are county court searches, state repository searches, federal court searches, fingerprint-based FBI checks, and commercial national database searches. Each pulls from a different source and covers a different slice of criminal history, so no single check captures everything. A county search misses federal crimes. A federal search misses local misdemeanors. A national database search can flag records that no longer exist at the courthouse. Which combination you need depends on the role, the industry, and how much risk you’re willing to accept from gaps in coverage.
Alongside these, several specialized registries track narrower categories of legal status, such as sex offender registration, federal sanctions, and healthcare program exclusion. Those are covered further down.
County Court Searches
Most criminal prosecutions happen at the county level, which makes courthouse records the richest source of detail on someone’s criminal history. A county search pulls directly from court dockets and typically reveals felony and misdemeanor convictions, pending cases, active warrants, and dismissed charges within that specific jurisdiction. The records often include sentencing details and case disposition information that broader searches miss entirely.
The obvious limitation is geographic. A county search only covers that one county. If someone committed a crime in a neighboring county or across state lines, it won’t appear. Employers who know where an applicant has lived tend to run county searches in each of those locations rather than relying on a single one. For positions where thoroughness matters more than speed, county-level checks remain the most accurate option.
State Repository Searches
State searches pull from a central repository typically maintained by a state’s department of public safety or law enforcement agency. These databases aggregate records from counties across the state into a single report, saving you the trouble of searching each county individually. Fees vary widely from state to state, ranging from free in some jurisdictions to over $100 in others.
The convenience comes with a trade-off. Smaller courts and rural jurisdictions sometimes lag in reporting to the state repository, so a recent arrest or conviction may not appear for weeks or even months. State databases also vary in what they include. Some contain only felonies, while others cover misdemeanors and traffic offenses. A state search works best as a complement to targeted county searches rather than a replacement.
Federal Criminal Record Checks
Federal courts handle a distinct set of crimes that never pass through state or local systems. U.S. District Courts have exclusive jurisdiction over federal offenses, which means a standard county or state search will not pick them up at all.1Office of the Law Revision Counsel. 18 U.S.C. 3231 – District Courts Tax evasion, securities fraud, immigration violations, and drug trafficking across state lines are all prosecuted in the federal system. So are crimes committed on federal property like military bases and national parks.
Investigators access federal court records through PACER (Public Access to Court Electronic Records), which provides case and docket information from federal appellate, district, and bankruptcy courts. PACER charges $0.10 per page with a $3.00 cap per document.2PACER. PACER Pricing: How Fees Work Federal checks are standard practice for positions involving government contracts, financial oversight, or security clearances.
Fingerprint-Based FBI Checks
The FBI’s Identity History Summary check uses fingerprints rather than names to match records, which eliminates the false-positive problem that plagues name-based searches. The FBI won’t run a name-based search for these requests. Fingerprint submission is the only option.3Federal Bureau of Investigation. Identity History Summary Checks Frequently Asked Questions Fingerprints are typically captured electronically at authorized collection sites through a process called LiveScan.
Because the FBI database draws on arrest data submitted by law enforcement agencies nationwide, it provides the broadest single-source criminal history available. The fee is $18.3Federal Bureau of Investigation. Identity History Summary Checks Frequently Asked Questions These checks are commonly required for professional licensing in healthcare, education, and finance, as well as for immigration applications and adoption proceedings. The main limitation is that the FBI database depends on agencies actually submitting their records, and not all do so consistently.
National Database Searches
National criminal databases are commercial products assembled by private companies, not government agencies. They compile records from state repositories, departments of corrections, and court systems across the country. A national search is useful for spotting records in unexpected jurisdictions where you wouldn’t otherwise think to look, but it’s only as current as the last time the vendor pulled data from each source.
This is where most screening mistakes happen. A national database might show a record that has since been dismissed, expunged, or updated because the vendor hasn’t refreshed that particular source recently. Any hit from a national database should be verified by going back to the original court of record before you act on it. Responsible screening companies treat national database results as leads, not conclusions. Consumer reporting agencies are also legally required to follow reasonable procedures to ensure “maximum possible accuracy” in the reports they produce.4Federal Trade Commission.

Specialized Registries and Watchlists
Some checks target narrow categories of legal status that a general criminal background check may not capture. Three are commonly bundled into employment and compliance screening.
Sex Offender Registries
The Dru Sjodin National Sex Offender Public Website (NSOPW.gov) aggregates registration data from every state, territory, the District of Columbia, and participating tribal jurisdictions into a single free search tool.5Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking. The National Sex Offender Public Website: Your Go-To Resource for Sex Offender Information Results include names, aliases, photographs, addresses, conviction details, and identifying features. Checking this registry is standard practice for roles involving children, vulnerable adults, or residential management.
OFAC Specially Designated Nationals List
The U.S. Treasury Department’s Office of Foreign Assets Control publishes the Specially Designated Nationals and Blocked Persons (SDN) list. It includes terrorists, narcotics traffickers, and entities controlled by or acting on behalf of sanctioned countries. U.S. persons are prohibited from conducting any transactions with anyone on the list, and their assets must be blocked.6U.S. Department of the Treasury. Specially Designated Nationals (SDNs) and the SDN List Financial institutions, companies with international operations, and organizations in regulated industries routinely screen against this list.
OIG Healthcare Exclusion List
The Department of Health and Human Services Office of Inspector General maintains the List of Excluded Individuals and Entities (LEIE). Anyone on this list is barred from participating in Medicare, Medicaid, and all other federal healthcare programs. If a healthcare employer hires an excluded person, no federal healthcare payment will be made for anything that person furnishes, orders, or prescribes, and the prohibition extends to the employer as well.7Office of Inspector General. Exclusions FAQs
How Far Back Each Check Can Reach
Federal law restricts how far back a background report can reach for most types of negative information. Under the Fair Credit Reporting Act, consumer reporting agencies cannot include arrest records older than seven years, unless the relevant statute of limitations is longer.8Office of the Law Revision Counsel. 15 U.S.C. 1681c – Requirements Relating to Information Contained in Consumer Reports The same seven-year ceiling applies to civil suits, civil judgments, and most other adverse items.
Criminal convictions are the major exception. Convictions can appear on a background report indefinitely under federal law. There is no time limit.8Office of the Law Revision Counsel. 15 U.S.C. 1681c – Requirements Relating to Information Contained in Consumer Reports A 20-year-old felony conviction is fair game federally, which is why state restrictions matter.
There’s also a salary-based exception that catches people off guard. The seven-year limit on non-conviction records does not apply to positions paying $75,000 or more per year.8Office of the Law Revision Counsel. 15 U.S.C. 1681c – Requirements Relating to Information Contained in Consumer Reports For higher-paying roles, screening companies can report the full history regardless of how old the records are. Some states impose stricter limits that override this federal exception, including a handful that cap conviction reporting at seven years regardless of salary, but federal law sets the floor.
What Rights You Have When a Check Is Run
Whenever an employer or other entity uses a third-party consumer reporting agency to run a check for employment purposes, the FCRA sets a required procedure. Before pulling the report, the requester must give you a clear written disclosure in a standalone document and obtain your written authorization.9Office of the Law Revision Counsel. 15 U.S.C. 1681b – Permissible Purposes of Consumer Reports If the report contains something that could cost you the job, the employer must send you a copy along with “A Summary of Your Rights Under the Fair Credit Reporting Act” before making a final decision, so you have a chance to review it and flag any errors.10Federal Trade Commission. Using Consumer Reports: What Employers Need to Know
If you find inaccurate information, you can dispute it directly with the consumer reporting agency. The agency must conduct a reinvestigation free of charge and resolve the dispute within 30 days of receiving your notice, extendable by up to 15 additional days if you submit new information during the initial period.11Office of the Law Revision Counsel. 15 U.S.C. 1681i – Procedure in Case of Disputed Accuracy If the disputed item can’t be verified, the agency must delete or correct it.
