Verifying a PI's License in Ohio
Before retaining any private investigator in Ohio, verify the individual’s license is active and in good standing. The Ohio Department of Public Safety — Private Investigator and Security Services (PISGS) maintains a public license search at https://services.dps.ohio.gov/PISGS/Pages/public/Search.aspx. Search by the individual’s name or company name; the record will show the license number, status, and any disciplinary history on file.
What This Means for Hiring
Ohio’s licensing requirement means the investigator you hire has, at minimum, completed the state’s training and background screening process. It does not guarantee competence on your specific case — surveillance, family-court, corporate, and skip-trace work each demand specialized experience. When evaluating a Ohio PI, ask about case-type specialization, evidentiary chain-of-custody process, and prior testimony in the jurisdiction where your matter is pending.
