Hiring a private detective

How to Verify a Private Detective's License

A license number on a website isn't proof. Verifying it yourself takes a few minutes and tells you whether the detective is in good standing.

Key points

  • Identify the state regulator where the work happens
  • Search by name and license number
  • Check status, expiration and any discipline

Find the right regulator

Licensing is handled state by state, and the regulator differs: a state police agency in some states, a licensing board or department of commerce in others. A few states have no statewide license at all.

Each of our state guides names the regulator and links to its official website. Start at our service areas page and choose the state.

Search the license

Most regulators have an online license lookup. Search by the individual's name and, if you have it, the license number. Check the agency license too, since many states license both firms and individuals.

Read the record

Confirm the license is active, not expired, suspended or revoked. Note the license type; some states have apprentice or employee registrations that require supervision. Look for disciplinary actions where they're published.

If the state doesn't license detectives

In states without a statewide license, ask about business registration, insurance, experience and references, and check for local licensing where it applies.

Red flags

A license that can't be found, a name mismatch, a license in a different state than where the work will happen, or reluctance to share a license number are all reasons to slow down.

Common questions

Do all states license private detectives?

No. A few states have no statewide license. Our state pages note where licensing is local or absent.

Can an out-of-state detective work in my state?

It depends on the state. Some have reciprocity or temporary permits; others require a local license. Ask how the work will be handled lawfully.

Where can I complain about a detective?

The state regulator usually handles complaints about licensees.
