So you want to become a private investigator. You’ve come to the right place!
Last update: January 2022
Investigate our archives to find articles by veteran private investigators about cases they’ve worked, tech tools they love, and how they became PIs. It’s a great place to learn about the incredible variety of work they do, from surveillance to criminal defense investigations to adoption searches. In our virtual pages, you’ll learn about niche work and investigative techniques like OSINT, K9 evidence, and trash pulls. And at our YouTube channel, you’ll find a deep archive of webinar interviews with P.I.s who share their wisdom every month.
Scroll down to find basic information about the licensing statutes in your state and helpful links to regulatory agencies and PI associations. Many, but not all, states with licensure statutes also require continuing education. We have that! Check out our sister site, PI Education, to find courses approved in your state.
State licensing requirements are always changing, so think of this database as a starting point for your research and not the final word. The links for each state should lead you to more current and detailed information, including fees, applications to download, state laws, and license renewal schedules. Although statutes vary, most states that require licensure have a minimum age (usually 18 or 21, sometimes 25), will ask you to provide a photograph, proof of citizenship, and fingerprints (for a background check), and you’ll possibly need to pass an exam. Fees for the application, licensure, renewals, and background check vary widely.
A criminal record, history of drug abuse, or mental health issues may delay or preclude your licensure. Many statutes include language about “good moral character” and require personal references. Some states require previous investigative experience or education as well and may have separate agency and individual licensure. Several have entry-level employee registration or trainee licenses that let you work as an agency employee to gain the needed experience.

Arizona
Arizona’s statutes require both individual P.I.s and agencies to be licensed. Applicants for a private investigator license must be 18 (qualifications here). An agency license is issued to the “Qualifying Party” (QP), who must be 21+ and show proof of three years of investigative experience.
You can work as a P.I. without the three years of experience if you register as an employee of a P.I. agency. Then you’d gain your three years as an apprentice before going solo.

No matter what path you choose, every applicant (regardless of experience and qualifications) must successfully complete a 70-hour basic training course taught by a Board-approved instructor; you may attend Board-approved training classes on your own prior to being hired by a licensed company.

Mississippi
Anyone whatsoever can operate as a P.I. in Mississippi — even felons, according to this 2015 Clarion-Ledger article by legendary investigative journo Jerry Mitchell. All you need is a business license in the city or county where you live or do business — at a cost of around $25,
Richard A. Brooks, past president of the MPIA, has long championed licensure. He lobbied hard for a 2015 bill (HB 713) to license and regulate MS PIs. It passed the state House but died in the Senate Judiciary Committee…RIP.
That means it falls to you to regulate yourself, learn the trade, and do business ethically. We recommend you join the MPIA and seek out colleagues — or better yet, a mentor — who can answer your questions about techniques, marketing, and investigative ethics.

Missouri
In Missouri, a private investigator must be licensed, and anyone wishing to operate a firm that employs other investigators also needs an agency license. These are two separate applications. Applicants for the private investigator license must be 21 and show proof of $250K of business liability insurance and worker’s comp insurance. If you have investigative experience, you can include proof of your work history (e.g., references, copy of the business license, etc.). If you have little or no experience, that’s OK — the board director will review your application and decide whether you’re good to go or need to first pass a written exam ($80) to be approved for licensure.
Although you may apply for the individual and agency licenses simultaneously, the board will approve the individual license first, then review the agency license. This requires a separate application (and fee) and a physical address for your business.
If you want to work for an agency, you’ll use the investigator employee application. That qualifies you to work for a specific agency. If you leave that agency, you’ll have to apply all over again for work for a different one.
