A surprising number of jobs require some form of state certification or license, which can provide good information about that person. This can determine if the person actually has their claimed profession, some personal details, and very often it will show any issues the person has run into. So in some cases a person had been suspended and the reason will be identified. But even a worker in good standing will have some relevant details in their license.
If you are researching anyone where you know their profession, it is worth a quick Google search asking if that profession requires a license in that state, or in general.
The website Career One Stop has a great tool (https://www.careeronestop.org/toolkit/training/find-licenses.aspx) that lists out all of the jobs requiring licenses and allows you to search by job title and state to see what kind of licensing requirements exist and where the public can look up an individual’s license.
