Why the Check Matters
New York requires a license from the Department of State to run or advertise a private investigation business. An unlicensed investigator is breaking state law before your case even starts. That can put your money at risk. It can also weaken evidence you plan to use with a lawyer or in court.
A license is not proof of skill, but it is the floor. Checking it takes less time than a phone call.
How to Search, Step by Step
- Ask for the license number. Ask for the agency license and the name of the licensed principal. A real agency answers right away.
- Open the state search. Go to the Department of State Licensee Search and choose to search a licensee.
- Pick the license type. Choose private investigator from the list of license types.
- Search one of three ways. Use the unique ID or registration number, a person's last and first name, or the business name. You can add a city, ZIP code or county to narrow it down.
- Compare the result. The name, business and location should match the investigator you spoke with.
What It Means If Nothing Comes Up
The state search shows active licenses only. If you find nothing, the license may have expired, the name may be spelled another way, or the person may never have been licensed.
Try the business name instead of the person's name. Try fewer words. If you still find nothing, ask the investigator to explain. Some investigators work as employees of a licensed agency, so the license may be under the agency name. Ask which agency holds it, then search that name. If the answers do not add up, keep looking for someone else.
What a License Check Does Not Tell You
- How many years the investigator has done your kind of case.
- Whether past clients were happy.
- Whether they carry insurance beyond what the state requires.
- Whether they have testified or written reports used in court.
Ask about each one. Ask for a sample report with private details removed. Ask how they bill. Our guide on what a private investigator costs in NYC lists the cost questions.
Save What You Find
Take a screenshot of the search result and note the date you checked. Write down the license number, the name on the license and the business name. Keep it with your agreement.
This helps if anything goes wrong later. If you ever need to file a complaint, the Department of State will want the license details. If your lawyer asks who did the work, you will have the answer in one place. It also helps you spot a problem if the name on your invoice does not match the name on the license.
It is fair to check again if your case runs for months. A license lasts two years in New York, so one could lapse while your case is still open.
Red Flags on the First Call
- They will not give a license number.
- They promise results before they know the facts.
- They offer phone records, account access or wiretaps. Those are crimes, not services.
- They want cash only with no written agreement.
- They claim police powers or hint that they can act like police.

How NYI Uses the Same Check
New York Investigators checks the state license before a member profile goes live, then checks it again every year. Members who earn higher tiers also prove years in business and other claims. You can see the rules on the certifications page and compare investigators in the directory. Still, check the license yourself. It is your case.
Common Questions
How do I look up a private investigator license in New York?
Use the Licensee Search on the NYS Department of State website. Search by ID number, a person's name or a business name.
Does the New York search show expired licenses?
No. The state search shows active licenses only, so an expired license will not appear.
What if the investigator works for an agency?
Ask which licensed agency they work under, then search the agency's business name in the state tool.
Is a PI license the same as being vetted?
No. A license shows the state minimum was met. It does not show years of experience, reputation or skill, so ask about those too.
