How to Run a Background Check — And What PIs Can Find That You Can't
Consumer background check websites give you a fraction of the picture. Here's what a licensed investigator can legally access that you can't — and why it matters before you hire, date, or partner with someone.
Free and low-cost background check websites are popular, but they're built on public data aggregators that are often outdated, incomplete, or flat-out wrong. They miss sealed records, out-of-state activity, and anything that hasn't been digitized.
A licensed private investigator has access to professional-grade databases that aggregate court records, property records, civil judgments, liens, professional license history, and verified address history going back decades — not just what's been indexed online.
PIs can also conduct in-person interviews and neighborhood canvasses that no algorithm can replicate. A neighbor, former coworker, or landlord can tell you things that never appear in any database.
Common use cases: vetting a new business partner before signing a contract, checking on someone you met online before meeting in person, verifying a caregiver's background before they enter your home, or confirming employment and credential claims.
There are legal limits. Private investigators in Arizona must comply with the Fair Credit Reporting Act (FCRA) when background checks are used for employment, housing, or credit decisions. A reputable PI will tell you upfront what they can and cannot legally provide for your specific use case.
The cost of a professional background check is almost always less than the cost of the mistake you're trying to avoid. Whether it's a bad hire, a fraudulent partner, or a dangerous stranger — knowing the truth before you commit is always worth it.
