Types of Criminal Record Checks: A Complete Hiring Guide

Criminal record checks are defined as formal background screening processes that search criminal history databases at the federal, state, county, or commercial level to verify whether an individual has a documented offense. Whether you are a police chief vetting a new recruit, an HR director screening a job applicant, or a nonprofit coordinator clearing a volunteer, the types of criminal record checks you choose determine the accuracy, scope, and legal defensibility of your hiring decision. The FBI Identity History Summary, state repository searches, county courthouse records, and commercial database aggregations each serve distinct purposes. Selecting the wrong type for your context creates liability. Selecting the right combination protects your organization and the people it serves.

1. What are the main types of criminal record checks?

Criminal record checks fall into four primary categories: federal (FBI), state, county, and commercial. Each category differs in jurisdiction, data source, verification method, and acceptable use case. No single check covers every record in every jurisdiction, which is why high-stakes roles in public safety, government, and licensed professions typically require more than one type.

The industry standard term for this process is “background investigation” when conducted at a professional or investigative level. The phrase “criminal record check” is widely used in HR and compliance contexts to describe the same process at varying depths. Both terms appear throughout this guide because both reflect real-world usage across hiring, licensing, and legal compliance.

Understanding the distinctions between check types is not optional for organizations with public trust responsibilities. A law enforcement agency that relies solely on a commercial database check for a sworn officer candidate is operating below the standard of care the profession demands.

2. FBI Identity History Summary checks

The FBI Identity History Summary is the gold standard for criminal background verification in the United States. It is fingerprint-based and nationwide, covering all 50 states plus federal records. No other single check matches its geographic scope or biometric accuracy.

The cost is $18 for the FBI processing fee, plus fingerprinting fees that typically range from $10 to $50 depending on the provider. Processing takes 3–5 business days electronically, or up to 12–16 weeks if submitted by mail. Electronic submission through an FBI-approved channeler is the standard choice for time-sensitive hiring.

FBI checks are required or strongly preferred in several specific contexts:

  • International visa and immigration applications
  • Federal employment and security clearance processes
  • Professional licensing in healthcare, law, and finance
  • Adoption proceedings
  • Firearm purchase eligibility determinations
  • Certain public safety and law enforcement hiring programs

The accuracy advantage of the FBI check comes from biometric verification. Fingerprints uniquely identify individuals and eliminate the false positives and false negatives that plague name-based searches. A candidate named “John Smith” in a name-based system could return dozens of irrelevant records or miss a conviction filed under a slightly different spelling.

Pro Tip: If your organization hires for roles that involve access to vulnerable populations, federal facilities, or classified information, treat the FBI Identity History Summary as a non-negotiable baseline, not an optional upgrade.

3. How state criminal record checks differ and who orders them

State criminal background checks search the criminal history repository maintained by an individual state’s law enforcement or court administration agency. They cover only offenses recorded within that state’s jurisdiction. An applicant who committed a felony in Texas will not appear on a California state check.

State rules vary widely across jurisdictions. Some states require fingerprint submission for official checks, while others permit name-based requests from employers or individuals. This variability directly affects reliability. A fingerprint-based state check is significantly more accurate than a name-based one from the same state.

Common use cases for state criminal background checks include:

  • State government employment and contractor vetting
  • Professional licensing at the state level (nursing, teaching, real estate)
  • Local law enforcement hiring where state law mandates a specific repository search
  • Volunteer screening for state-regulated programs
  • Tenant screening in jurisdictions that permit it

State checks are faster and less expensive than FBI checks in most cases, but their limited jurisdiction is a real constraint. An applicant who lived in three states before applying to your agency requires three separate state checks to achieve equivalent coverage. That is why combining FBI and state checks is often necessary for comprehensive background screening in public safety roles.

4. What county and local criminal record checks cover

County criminal record checks search the court records of a specific county or municipality. They are the most granular level of criminal background screening available and often capture records that do not appear in state repositories, particularly for minor offenses, local ordinance violations, and cases that were filed but not yet entered into the state system.

County checks are accessed directly through courthouse records, either in person or through a court records retrieval service. They are not automated in the way commercial databases are. A researcher physically pulls the docket from the clerk’s office or accesses the court’s electronic filing system for that specific jurisdiction.

Key facts about county-level checks:

  • They cover only one county or municipality per search
  • They are the most accurate source for local offense records
  • They capture cases that state repositories may lag in updating
  • They are commonly used for local government employment and volunteer screening
  • They are not practical as a standalone check for applicants with multi-state histories

Pro Tip: For candidates who have lived in multiple counties within the same state, order individual county checks for each location of residence. State repositories sometimes take weeks or months to reflect newly filed cases, but the county courthouse record is current.

The value of county checks is highest when you need to verify local records with precision. For a fire department hiring a paramedic who has lived in the same metro area for 20 years, a county check for that jurisdiction adds meaningful depth beyond what a state or commercial check provides.

5. What commercial background checks are and how they compare to official records

Commercial background check services aggregate criminal history data from multiple public and private sources into a single searchable database. They are typically name-based and return results within minutes to a few days, making them attractive for high-volume hiring environments.

Commercial checks aggregate data from court records, state repositories, sex offender registries, and other public sources, but they do not replicate the content of FBI or official state checks. Their proprietary algorithms and source compilations introduce gaps. A record that exists in a county courthouse may not appear in a commercial database if that county has not been indexed or if the data has not been updated recently.

Feature Commercial check Official (FBI/state/county) check
Verification method Name-based (usually) Fingerprint or direct court access
Turnaround time Minutes to 2 days 3–5 days (FBI electronic) to weeks
Geographic scope Multi-state aggregation Jurisdiction-specific
Accuracy for common names Lower (false positives likely) Higher (biometric or direct record)
Acceptable for high-stakes roles No Yes
Cost Low to moderate Moderate to higher

Commercial checks work well as a preliminary screening tool or for roles with lower risk profiles. They are not appropriate as the sole check for law enforcement, EMS, government, or any position involving access to weapons, vulnerable populations, or sensitive data. False matches in name-based searches arise frequently from common names and discrepancies in court record entries, creating both false positives that harm innocent applicants and false negatives that miss actual offenders.

6. National criminal checks and what they actually cover

A national criminal background check is a commercial product, not a government database. The term is widely used but frequently misunderstood. National checks aggregate records from all 50 states, including felonies, misdemeanors, warrants, and sex offender registries, but they exclude federal records. Federal criminal history requires a separate FBI check.

The “national” label implies completeness, but the actual coverage depends on which counties and states have been indexed by the provider. Rural counties and jurisdictions with older paper-based filing systems are frequently underrepresented. An applicant with a conviction in an unindexed county will appear clean on a national commercial check.

For public safety background investigations, relying on a national commercial check as a primary tool creates a documented gap in your screening process. Regulatory bodies and accreditation organizations increasingly scrutinize the methodology behind hiring decisions, not just the outcome.

7. How to choose the right type of criminal record check

Selecting the right check type requires matching the check’s scope and verification method to the legal requirements, risk level, and jurisdictional needs of the specific role.

Fair Chance and “ban the box” laws require many employers to delay criminal background checks until after a conditional offer of employment. These laws apply in dozens of states and municipalities. Running a check before a conditional offer in a covered jurisdiction creates legal exposure regardless of what the check reveals.

Consider accuracy relative to the role’s risk level

  • FBI Identity History Summary: Required or strongly preferred for sworn law enforcement, federal contractors, licensed healthcare workers, and anyone with access to weapons or classified information.
  • State repository check: Appropriate for state-licensed roles, local government positions, and as a complement to the FBI check for jurisdiction-specific records.
  • County courthouse check: Add for candidates with long residential history in a specific area, or when a state repository is known to have update delays.
  • Commercial check: Acceptable as a preliminary screen or for lower-risk volunteer roles, but never as the sole check for high-stakes positions.

Budget and turnaround time

FBI electronic checks cost $18 plus fingerprinting fees and return results in 3–5 business days. State checks vary by jurisdiction but are generally comparable in cost. County checks add per-county fees and retrieval time. Commercial checks are the least expensive and fastest but carry the accuracy trade-offs described above.

Combine check types for comprehensive coverage

Comprehensive background screening for public safety roles typically requires an FBI check plus relevant state checks plus county checks for each jurisdiction where the candidate has lived or worked. This combination addresses the gaps that any single check type leaves open. Organizations that comply with background regulations for public safety hiring document their check methodology as part of their legal defense posture.

Pro Tip: Review your state’s specific Fair Chance law before designing your screening workflow. The timing of when you order each check type, not just which checks you order, determines your legal compliance.

Key takeaways

The most defensible criminal background screening process combines FBI, state, and county checks matched to the role’s risk level and legal requirements, with commercial checks used only as a preliminary tool.

What I’ve learned from years of watching agencies get this wrong

The most common mistake I see organizations make is treating a commercial background check as a complete background investigation. It is not. A commercial check is a starting point at best and a false sense of security at worst.

Agencies that hire sworn officers, armed security personnel, or EMS responders based on a name-based database search are not conducting background investigations. They are conducting a keyword search on a partially indexed commercial product. The difference matters enormously when an incident occurs and the hiring decision is scrutinized.

The second mistake is failing to self-check. Individuals can legally check their own criminal records before applying for positions, and doing so is one of the most practical steps a candidate can take. Errors in criminal records are more common than most people realize. A candidate who discovers a misattributed record before an employer sees it has time to dispute it. A candidate who discovers it during a hiring process does not.

The third mistake involves Fair Chance compliance. Fair Chance hiring laws shift when checks are performed, and organizations that have not updated their screening workflows to reflect current law are creating liability with every hire. The legal framework around criminal background screening is not static. It requires active monitoring.

My practical advice: build your screening methodology around the FBI Identity History Summary as the floor, not the ceiling. Add state and county checks based on the candidate’s residential history. Use commercial checks only as a preliminary filter, never as a final determination. And document every step of your process.

FAQ

What is a criminal record check?

A criminal record check is a formal search of criminal history databases at the federal, state, county, or commercial level to determine whether an individual has documented offenses. The scope and accuracy of the check depend on which databases are searched and whether the search is fingerprint-based or name-based.

What is the most accurate type of criminal background check?

The FBI Identity History Summary is the most accurate criminal background check available. It uses fingerprint-based biometric verification and covers all 50 states plus federal records, eliminating the false matches common in name-based searches.

Do I need both a federal and a state criminal background check?

Yes, for most high-stakes roles. Federal and state checks cover different records. An FBI check covers nationwide criminal history, while a state check captures jurisdiction-specific records that may include offenses not entered into federal databases.

What does a national criminal background check include?

A national criminal background check aggregates records from all 50 states, including felonies, misdemeanors, warrants, and sex offender registries, but it does not include federal criminal records. Federal history requires a separate FBI Identity History Summary check.

When can an employer legally run a criminal background check?

Fair Chance and “ban the box” laws in many states and municipalities require employers to delay criminal background checks until after a conditional job offer. The specific timing rules vary by jurisdiction, so organizations must verify the applicable law for each location where they hire.
