There is no single thing called "a background check". The term covers 10+ distinct check types, each pulling from a different data source, each with its own legal rules, cost, and turnaround. Picking the right combination for a role is the difference between meaningful risk screening and theatre.
This guide walks the 10 most common background check types employers run, what each one surfaces, when to use it (and when to skip), the cost range, and how long it takes. Use it to build the screening package that matches the role, not the package your provider is upselling.
Why the right check matters more than running more checks
Running every available check on every candidate looks thorough. It is actually expensive, slow, and creates compliance exposure. Three reasons to be deliberate:
- Cost. A full check stack can run $80 to $200 per candidate. Multiply by your hiring volume.
- Time. Each check adds days. A 10-check stack often takes 2x as long as a focused 4-check stack.
- Compliance. Some checks (credit, criminal beyond 7 years, salary history) are restricted in specific states. Running them everywhere creates risk.
The right approach: pick the 3 to 5 checks that match the actual risks of the role. The list below tells you what each one surfaces so you can pick.
1. Identity verification / SSN trace
Confirms the candidate is who they say they are. Cross-references the SSN, name, and date of birth against credit bureau records to surface aliases and address history.
- Cost: $5 to $15 per check
- Turnaround: Under 1 day
- Best for: Every role. Identity is the foundation of every other check.
- Skip if: Almost never. This is the cheapest check and prevents the worst outcome (hiring someone who is not who they claim).
2. Criminal records (multi-state database)
The "instant" criminal check. Searches a multi-state aggregator database covering most US states. Fast, broad, but not always complete.
- Cost: $10 to $25 per check
- Turnaround: Minutes to 1 hour
- Best for: First-pass screening. Most providers run this as the entry point.
- Limit: Database coverage is not perfect. Pair with county courthouse searches for the addresses the candidate has lived.
3. Criminal records (county courthouse)
The deeper criminal check. Searches court records at the actual county level where the candidate has lived. More thorough than the database, slower and more expensive.
- Cost: $10 to $20 per county
- Turnaround: 1 to 7 business days per county
- Best for: Roles where the cost of a missed criminal record is high (positions of trust, healthcare, finance, work with vulnerable populations). For full guidance on timing, see our breakdown of how long background checks take by type.
- Coverage: Search the counties where the candidate has lived in the last 7 years (FCRA reportable window).
4. Federal criminal records
Different database, different jurisdiction. Federal crimes (tax fraud, drug trafficking, interstate crimes) live in federal court records (PACER), not county or state systems.
- Cost: $10 to $25
- Turnaround: 1 to 3 business days
- Best for: Roles handling money, financial data, government contracts, or interstate commerce.
- Skip if: The role does not handle financial or regulated information. Most retail and operational roles do not need this.
5. Sex offender registry
Searches the national and state sex offender registries.
- Cost: $5 to $10
- Turnaround: Minutes
- Best for: Required for roles involving children, elderly, or vulnerable populations (healthcare, education, childcare).
- Note: Often bundled into the criminal check.
6. Motor vehicle records (MVR)
The driving record. Pulls history of license suspensions, DUIs, points on the license, and overall driving infractions from the state DMV.
- Cost: $5 to $20 per state
- Turnaround: Real-time to 3 days depending on state
- Best for: Any role involving driving for work. Delivery, sales reps, field service, transportation. Required by DOT regulations for commercial drivers.
- Skip if: The role does not involve work-related driving.
7. Employment verification
Confirms the dates, titles, and (if authorized) salaries claimed on the resume by contacting previous employers.
- Cost: $15 to $30 per employer
- Turnaround: 3 to 5 business days per employer
- Best for: Almost every role. Resume fabrication is more common than employers like to admit.
- Speed tip: Large employers using The Work Number return in under a day. Small employers can take 1 to 2 weeks.
8. Education verification
Confirms degrees, dates, and institutions on the resume. Uses the National Student Clearinghouse for most US universities, manual verification for high schools and smaller institutions.
- Cost: $10 to $25 per credential
- Turnaround: 3 to 7 business days for US schools, 2 to 4 weeks for international
- Best for: Roles where the specific degree is required (regulated professions, technical roles with credential requirements).
- Skip if: The degree is not required for the role. Most employers over-verify here.
9. Credit check
Pulls the candidate's credit report. Shows credit history, debt levels, bankruptcies, and collections.
- Cost: $15 to $30
- Turnaround: Instant to 3 days (depending on whether the candidate's credit is frozen)
- Best for: Roles handling money, financial data, or fiduciary responsibilities. Banking, accounting, executive finance roles.
- Compliance: Restricted in 11+ US states for employment use. Check state-by-state requirements before running.
- Skip if: The role does not handle finances. Credit checks for non-financial roles invite legal exposure for limited benefit.
10. Drug screening
Tests for substance use through urine, hair, or saliva samples.
- Cost: $30 to $100 depending on panel
- Turnaround: 1 to 3 business days (5 to 7 for hair tests)
- Best for: DOT-regulated roles, safety-sensitive positions, healthcare, federal contractor roles where required.
- Compliance: Marijuana-specific rules vary by state. Several US states restrict pre-employment marijuana testing.
- Skip if: No safety or regulatory reason to test. Industry standards have shifted away from drug testing for non-safety-sensitive roles.

How to build the right check stack for a role
Three questions to scope the right stack:
- What is the real risk? Match checks to specific risks. Customer-data role: identity + criminal + employment. Driving role: identity + criminal + MVR. Healthcare: identity + criminal + sex offender + drug + license. Stop bundling defaults you do not need.
- What is the candidate experience cost? Each check adds 1 to 7 days. A 10-check stack for a $50K admin role is bad candidate experience for marginal risk reduction.
- What does the law require here? Some checks are required by regulation (DOT drug screening, FBI fingerprint for some healthcare). Some are restricted by state. Compliance shapes both what you must run and what you must not run.
FCRA compliance basics
Almost every employment background check in the US falls under the Fair Credit Reporting Act. Three rules every employer running checks needs to follow:
- Standalone disclosure and authorization. The candidate signs a separate document authorizing the check. Embedding it in the offer letter or application form violates FCRA. Use a dedicated background check form with the disclosure on a standalone document.
- Pre-adverse action notice. Before deciding not to hire based on the report, give the candidate a copy of the report and a reasonable time (typically 5 business days) to dispute.
- Adverse action notice. If you proceed with the no-hire after dispute, send a formal notice with the candidate's rights and the consumer reporting agency's contact info.
The FTC publishes employer-side guidance on FCRA compliance worth bookmarking.
The takeaway
Picking the right 3 to 5 background checks for the role beats running every check available. Identity + criminal (multi-state + county) + employment is the right starting stack for most roles. Add MVR for driving roles, credit for financial roles, drug for safety-sensitive, education for credentialed positions. Skip the rest unless there is a specific risk or compliance reason. Pair the stack with a complete FCRA-compliant consent form, communicate the timeline to candidates, and most of the friction in background screening goes away.
