Can anyone verify if this is legit?

First off I want to apologize if this is the wrong subreddit to ask this sort of question. Anyways I'm trying to get my TABC and food handlers certification and after paying for the course it asks for my SSN in full before I can even start. I looked up the laws for where I live on this law and got mixed results some places say it is required and some do not (I live in Texas). The website I brought from is here and it redirects me to a .com (useusa/ Fusion a certus solution). Thanks
