Background checks and due diligence answer one question: is this person or business who they say they are? The stakes vary from a new hire to a tenant to a romantic partner to a business acquisition, but the discipline is the same: verify claims against primary sources rather than trusting a profile.
This guide explains what a licensed investigator actually checks, how that differs from a consumer people-search site, and the legal rules that govern certain checks. We match you with NYS-licensed investigators; we do not run the checks ourselves.
What a Professional Check Covers
A professional background investigation combines database access with verification work that consumer services do not perform. Depending on the purpose, it can include criminal history across multiple jurisdictions, civil litigation records, bankruptcies and liens, address and employment history, professional license verification, and analysis of public social media.
The difference that matters is verification. A licensed investigator can confirm a claim through direct contact and source interviews, not just report what a database returned. For high-stakes decisions, that distinction is the whole point.
When the FCRA Applies
The Fair Credit Reporting Act (FCRA) governs background checks used for employment, tenancy, and credit. When a check is run for one of those purposes, specific rules apply: the subject must consent, and if an adverse decision is based on the report, the subject is entitled to notice and a copy. This is federal law, and New York layers on additional protections, including limits on the use of criminal history in hiring.
A pre-employment or tenant-screening check is FCRA-regulated and requires consent and disclosure. A personal pre-relationship check on someone you are dating is not an FCRA purpose, but it still cannot rely on unlawful access to private records. A reputable investigator scopes the check to the purpose and stays inside the rules.
When Due Diligence Is Worth It
Due diligence pays for itself when the downside of being wrong is large: hiring an executive with financial authority, signing a lease with a high-value tenant, entering a business partnership, or committing to a relationship that involves shared finances or children. In each case the cost of a check is small against the cost of the risk it surfaces.
A standard background check is often completed in three to seven business days. Multi-jurisdiction or executive-level due diligence, including source interviews and regulatory records, takes longer and is scoped individually.
Frequently Asked Questions
How is a PI background check different from an online service?
Consumer services pull limited, often outdated public records. A licensed investigator has access to professional databases, can verify information through direct contact and source interviews, and produces a report that carries evidentiary weight. The difference is verification, which matters most in high-stakes decisions.
Do I need someone's consent to run a background check?
For employment, tenant, or credit purposes the FCRA requires the subject's consent and disclosure if an adverse decision follows. A personal pre-relationship check is not an FCRA purpose and does not require consent, but it still cannot use unlawful access to private records.
How long does a background check take?
A standard check is usually completed in three to seven business days. Multi-jurisdiction or executive due diligence involving source interviews and regulatory records takes longer and is scoped to the specific case.
