Knowing who you are hiring has never mattered more. Whether you are scaling a startup or managing a global enterprise, the integrity of your team defines your results, and a single bad hire can cost you tens of thousands in salary, training and lost productivity.
A background check is how employers close that gap between what a candidate claims and what is verifiably true. This guide explains what a background check is, what it reveals, how long it takes, how far back it looks, and what you need to do to stay compliant.
What is a background check?
A background check is the process of verifying the accuracy of the information an individual has provided about themselves. For employers, it acts as a safety net: confirmation that the person you are about to hire is exactly who they claim to be.
The process typically involves validating criminal records, employment history, educational qualifications and identity documents. While background screening is most commonly used to screen job applicants during recruitment, it is also used to vet volunteers, tenants, contractors and business partners.
Background checks are not limited to a single country. Global background screening is used to verify employees and contractors who have lived, studied or worked across multiple jurisdictions, increasingly the norm in remote and distributed teams.

Implementing a screening strategy is more than a compliance box to tick. It has a direct effect on your hiring quality, your workplace safety and your culture.
Reduce chances of bad hires
The cost of a hiring mistake is significant. A widely cited figure attributed to the U.S. Department of Labor puts the cost of a bad hire at up to 30% of that employee's first-year earnings, covering recruitment spend, onboarding, training time and lost productivity. For senior roles, the real figure is often far higher once team disruption and client impact are counted.
Professional background screening filters out unsuitable candidates before they enter your organization, when the cost of saying no is still close to zero.
Verify candidates' identity and claims
Resume fraud is a growing concern. Research by StandOut CV (2024) found that roughly 64% of applicants have lied on their CV at least once. The most common falsifications include inflating salaries, exaggerating skills, and stretching employment dates to hide gaps.
A thorough check validates the facts, so you hire based on reality, not a well-written fiction.
Improve workplace safety and regulatory compliance
In government, finance, healthcare and defence, screening is often a legal or contractual requirement. Even where it is not mandatory, background screening protects your existing workforce, your customers and your clients from avoidable risk and demonstrates due diligence if something later goes wrong.
What screening actually looks like day to day
Which checks are proportionate for which roles, how consent works, what candidates experience, and how results reach your dashboard. All explained in short, practical articles.

The scope of a background check varies depending on the role, the purpose of the check and the laws of the country where the candidate lives and works. A comprehensive screening package typically includes:
- Criminal Records: Checks for past convictions and legal issues to ensure workplace safety. Commonly used for safety-sensitive and publuc-facing roles.
- Employment History: Verifies past employers, job titles, and dates of employment to confirm experience. Commonly used for almost all professional roles.
- Education Verification: Confirms degrees and diplomas directly with the issuing institutions. Commonly used for graduate, technical and licensed roles.
- Credit Reports: Assesses financial responsibility (typically for finance-related roles). Commonly used for finance, accounting, fiduciary roles.
- Social Media Profiles: Checks for adverse media or behavior that could damage company reputation. Commonly used for leadership, brand-facing roles.
- Sanction and PEP Lists: Screens against global watchlists for political exposure or sanctions. Commonly used for Finance, AML-regulated sectors.
- ID Check: Verifies the validity of government-issued identification documents. Commonly used for every role.
Not every role needs every check. The strongest screening programmes match the depth of the check to the risk of the role, which is also what regulators expect to see.

Most standard employment background checks complete within 2 to 5 business days. Timelines depend on:
- The checks included. Identity and sanctions checks are near instant; education verification depends on an institution replying.
- The countries involved. International checks can add days or weeks, particularly where records are not digitized or require in-person retrieval.
- Candidate responsiveness. Consent forms and supporting documents are the most common source of delay.
Setting expectations with candidates up front and collecting consent early is the single most effective way to shorten turnaround.
How far back do background checks go?
There is no universal answer, because lookback periods are set by local law:
- Employment and education history is usually verified for the past 5 to 10 years, or for the roles relevant to the position.
- Criminal record checks are restricted in many jurisdictions. Some limit disclosure to convictions within the last 5 or 7 years, while others require spent convictions to be excluded entirely.
- Credit checks are typically limited to 6 or 7 years of history and are restricted to roles where financial responsibility is genuinely relevant.
If you hire across borders, assume the rules differ in every market and build your process around the strictest one that applies.
Are background checks legal? Compliance essentials
Background checks are legal in most countries, but they are tightly regulated. The core principles are consistent:
- Get written consent. Candidates must know what will be checked and agree to it before screening begins.
- Check only what is relevant. Under GDPR and similar regimes, you must be able to justify each data point against the requirements of the role.
- Apply the process consistently. Screening some candidates and not others invite discrimination claims.
- Give candidates a right of reply. If an adverse finding affects your decision, the candidate should have an opportunity to explain or dispute it.
- Store and delete data properly. Screening data is sensitive personal data with defined retention limits.
In the United States, the Fair Credit Reporting Act (FCRA) and EEOC guidance govern how results may be obtained and used. In the EU and UK, GDPR governs lawful basis, minimization and retention. Rules change, confirm current requirements for each market with qualified legal counsel before finalizing your policy.
Different country, different rules. One platform.
Screening rules vary by jurisdiction, and getting them wrong is expensive. Pescheck runs checks across 195+ countries with the local legal requirements applied to each, so your process stays compliant wherever you hire.
See How It WorksHow to run a background check: a 5-step process
- Define your screening policy. Decide which checks apply to which role types and document the reasoning.
- Obtain informed consent. Provide a clear disclosure of what will be checked and why, then collect written authorization.
- Verify identity first. Every other check is only as reliable as the identity it is attached to.
- Run the role-appropriate checks. Use an accredited screening provider for regulated or international checks.
- Review, decide and document. Assess findings against the role, allow the candidate to respond to discrepancies, and record how the decision was made.
Frequently asked questions
- What is the difference between a background check and background screening?
The terms are used interchangeably. "Background screening" often describes the broader programme of checks an organization runs, while "background check" refers to the check performed on one individual.
- Can a candidate fail a background check?
There is no formal pass or fail. A check returns findings, and the employer decides whether those findings are relevant to the role. Unexplained discrepancies between a CV and verified records are the most common reason an offer is withdrawn.
- Do I need consent to run a background check?
Yes. In virtually every jurisdiction, informed written consent is required before screening begins.
- Can you run a background check on international candidates?
Yes. International background screening verifies records in each country where the candidate has lived, worked or studied, following that country's rules on what may be checked and disclosed.
- How much does a background check cost?
Costs vary by scope and country, typically ranging from a basic identity and sanctions package to comprehensive multi-country screening for senior hires.
