Private investigator licensing in the United States is set state by state, and the differences are bigger than for almost any other security job. Some states let you start with a few days of training; others require five years of experience, a minimum age of 25 and a five-figure bond. A handful don’t license investigators at the state level at all.
Licensing affects what you can earn, too. See our private investigator salary guide for pay by state and industry.

- Toughest: Connecticut, New Jersey and New York (age 25 and multi-year experience), Nevada (10,000 hours) and California (6,000 hours).
- Easiest entry: states with training-based, intern or apprentice routes, such as Virginia, Florida, Oregon, Utah, Alabama, North Carolina and Colorado.

States without a statewide license
Idaho, Mississippi and South Dakota have no state PI license, and Alaska and Wyoming leave regulation to cities. That doesn’t mean there are no rules: business registration, local permits and general privacy, trespass and recording laws still apply, and clients still expect insurance and experience.
Working in more than one state
A PI license is generally valid only in the state that issued it. A few states have reciprocity agreements; for example, Arkansas lists Tennessee, Louisiana and Oklahoma, and North Carolina lets investigators from partner states work a home-state case for up to 30 days. Otherwise, you’ll need a license in each state where you investigate, or a partnership with a locally licensed investigator.
