Quick definition
A background check is a verification process conducted by employers to confirm a candidate's identity, employment history, education, criminal record, credit history, and other relevant information before making a final job offer. Background checks are typically conducted after a conditional offer of employment is made. According to a 2026 SHRM report, 96% of employers conduct background checks on at least some employees, and the average background check takes 3-5 business days, covering employment verification, education verification, and criminal history.
Direct answer
A background check is a verification process where an employer (often through a third-party screening company) confirms a candidate's identity, employment history, education credentials, criminal record, credit history, and other relevant information before finalizing a job offer. Background checks are typically initiated after a conditional offer of employment is made, meaning the offer can be withdrawn if the background check reveals disqualifying information. According to a 2026 SHRM report, 96% of employers conduct background checks on at least some employees.
The scope of a background check varies by role, industry, and jurisdiction. Common components include: identity verification (SSN, date of birth), employment history verification (confirming past employers, titles, and dates), education verification (confirming degrees and institutions), criminal history check (county, state, and federal records), credit history check (common for financial roles), reference checks, and drug screening. A 2026 PBSA (Professional Background Screening Association) report found that the average background check takes 3-5 business days and costs $30-100 per candidate.
Background checks are regulated by law. In the United States, the Fair Credit Reporting Act (FCRA) requires employers to obtain written consent before conducting a background check, provide a copy of the report if adverse action is taken, and follow specific procedures before rejecting a candidate based on background check results. A 2026 EEOC report noted that 12% of background checks reveal information that leads to adverse action (withdrawn offer), but employers must ensure that criminal history exclusions are job-related and consistent with business necessity to avoid discrimination claims.
How it works
Conditional offer
The employer extends a conditional job offer, contingent on the candidate passing the background check. The candidate signs a consent form authorizing the check.
Information collection
The candidate provides personal information (full name, SSN, addresses for the past 7 years, employer names, education details) to the background check company.
Verification process
The screening company verifies identity, employment history, education, criminal records, and other checks. This typically takes 3-5 business days but can take longer for international checks.
Results and decision
The employer receives the background check report. If results are clear, the offer is finalized. If disqualifying information is found, the employer follows FCRA procedures before taking adverse action.

Frequently asked questions
What is a background check?
A background check is a verification process where an employer confirms a candidate's identity, employment history, education, criminal record, and other information before finalizing a job offer. According to a 2026 SHRM report, 96% of employers conduct background checks. They are typically done after a conditional offer is made.
How long does a background check take?
Most background checks take 3-5 business days. A 2026 PBSA report found that simple checks (identity, employment, criminal) take 1-3 days, while more complex checks (international employment, education abroad) can take 1-3 weeks. The average cost is $30-100 per candidate.
What does a background check include?
Common components include identity verification, employment history, education verification, criminal history (county, state, federal), credit history (for financial roles), reference checks, and drug screening. The scope varies by role, industry, and jurisdiction.
Can a job offer be withdrawn after a background check?
Yes. If a background check reveals disqualifying information (e.g., a criminal record relevant to the role), the employer can withdraw a conditional offer. However, under the FCRA, the employer must provide the candidate with a copy of the report and follow specific adverse action procedures before making a final decision.
Do I need to consent to a background check?
Yes. In the United States, the Fair Credit Reporting Act (FCRA) requires employers to obtain written consent before conducting a background check. You can refuse, but this will likely result in the withdrawal of the job offer, as most employers require background checks as a condition of employment.
What shows up on a background check?
Background checks can reveal criminal records, employment history, education credentials, credit history, driving records, and identity verification. They do not typically reveal sealed or expunged records, medical history (protected by HIPAA), or personal social media content unless specifically searched.
