Types of Background Checks for Employers: The Complete Guide
Not every background check is the same — and running the wrong type for the wrong role wastes money, misses real risks, and can even create legal liability. The most effective employer screening programs are targeted: the right checks for the right position, applied consistently and documented in writing.
This guide breaks down every major type of background check available to employers, explains what each reveals, and shows you how to build a tailored screening program that protects your company’s reputation, data, and people.
Why the Type of Background Check Matters
A daycare hiring a childcare worker needs different information than a bank hiring a loan officer, which needs different information than a logistics company hiring a fleet driver. A one-size-fits-all screening approach either over-screens (creating unnecessary legal exposure and candidate drop-off) or under-screens (missing role-specific risks that a targeted check would catch).
Understanding the available options — and knowing which combination applies to each role — is the foundation of a legally defensible, operationally effective hiring process.
The 7 Major Types of Background Checks for Employers
1. Criminal Background Checks
What it covers: Felony and misdemeanor convictions; pending charges; sex offender registry; federal, state, and county court records; most-wanted lists.
Best for: Nearly all roles, but especially positions with access to vulnerable populations, financial systems, physical premises, or sensitive data.
Criminal background checks are the most commonly run type of employer screening, and for good reason — they directly surface history that could pose a risk to employees, customers, or the organization itself.
Important nuance: EEOC guidance prohibits blanket policies that automatically disqualify candidates with any criminal record. Employers must conduct an individualized assessment considering the nature of the offense, how long ago it occurred, and its direct relevance to the job duties in question. Document this process in writing for every adverse decision.
2. Credit History Checks
What it covers: Credit score and payment history; outstanding debts and collections; bankruptcies; judgments; foreclosures.
Best for: Roles with financial authority — CFOs, controllers, accounts payable/receivable staff, wealth advisors, procurement managers, and anyone with access to company accounts or client financial data.
Credit checks are not appropriate for all roles, and several states restrict or prohibit their use in hiring decisions. Always confirm your state’s rules before running a credit check, and ensure the check is directly relevant to the financial responsibilities of the position.
A candidate who has navigated a personal financial crisis isn’t automatically a risk — but a pattern of fraud-related financial misconduct absolutely is.
3. Employment History Verification
What it covers: Confirmation of previous employers, job titles held, employment dates, eligibility for rehire (where legally permissible), and sometimes reason for departure.
Best for: All professional roles where experience and progression are material to the hiring decision.
Studies show that 85% of employers have caught a candidate lying on their résumé. Employment history verification is your primary defense against that. It catches inflated titles (“VP” for a job that was actually “Senior Analyst”), gaps disguised as employment, and employers who don’t actually exist.
Verification typically involves direct contact with previous HR departments or third-party employment verification services. Some employers use The Work Number (an Equifax service) for automated verification of current employment and income.
4. Education and Credential Verification
What it covers: Degrees awarded, institutions attended, enrollment dates, majors or fields of study, certifications and professional licenses.
Best for: Any role where specific educational credentials or professional certifications are a stated requirement — healthcare, law, engineering, education, finance, and others.
Degree fraud is more common than most employers realize. A 2017 study found that 17% of résumés contain education-related inaccuracies. For roles where a specific credential is legally required — a nursing license, a CPA designation, a teaching certificate — verification isn’t optional.
Education verification involves contacting the institution’s registrar directly or using a verification service. For professional licenses, most states maintain public licensing databases that can be checked instantly.
5. Professional License and Regulatory Verification
What it covers: Current license status; license expiration dates; disciplinary actions, suspensions, or revocations; sanctions and exclusions from government programs.
Best for: Healthcare workers (check OIG exclusion list), financial professionals (check FINRA BrokerCheck), real estate agents, attorneys, teachers, and any licensed profession.
This check is separate from education verification and often more important. A nurse can have a valid nursing degree and a revoked license — education verification alone won’t catch that. License verification checks the current status of a credential with the issuing authority.
For healthcare employers specifically, the OIG exclusion list check is mandatory. Employing an excluded individual and billing Medicare or Medicaid for their services can result in substantial civil monetary penalties.
6. Watchlist, Sanctions, and Global Screening
What it covers: OFAC Specially Designated Nationals list; FBI Most Wanted; Interpol notices; EU and UN sanctions lists; PEP (Politically Exposed Persons) databases; adverse media screening.
Best for: Financial institutions (required under Bank Secrecy Act and AML regulations), government contractors, international organizations, and any business operating in regulated industries.
Sanctions screening protects companies from unknowingly doing business with individuals or entities that are prohibited by federal or international law. Violations of OFAC regulations carry civil penalties up to $1.3 million per violation — making this check non-negotiable for financial services firms.
7. Reference Checks
What it covers: Direct feedback from previous supervisors, colleagues, or professional contacts about job performance, work ethic, interpersonal skills, and the candidate’s strengths and areas for development.
Best for: All roles, but particularly leadership positions, client-facing roles, and positions requiring strong collaboration or judgment.
Reference checks are the most qualitative type of background check — and the most commonly done poorly. Calling a candidate’s hand-picked references and asking generic questions yields little useful information. The most valuable reference conversations are structured: specific questions about the candidate’s actual performance, examples of how they handled failure, and a direct question about whether the reference would hire them again.
Specialty Checks Worth Knowing About
Beyond the seven core types, several specialized checks apply to specific industries and roles:
- MVR (Motor Vehicle Record) checks: Required for any employee who drives as part of their job. Surfaces DUIs, license suspensions, and at-fault accidents.
- Drug testing: Required in transportation (DOT-regulated), healthcare, and certain government contractor roles. Pre-employment, random, and post-accident drug testing are all common.
- Sex offender registry checks: Essential for any role involving minors, vulnerable adults, or overnight supervision. Often legally mandated for childcare, education, and healthcare roles.
- Social media screening: Analysis of public social media accounts for content that indicates dishonesty, harassment, discrimination, or conduct inconsistent with company values. Must be done carefully to avoid exposure to protected class information.
- I-9 and right-to-work verification: Legally required for all U.S. employers. Confirms that candidates are legally authorized to work in the United States.
