I am pretty sure it would be public info if a person has a business license or not. It s not something that is found online. Anyone can set up a website and even operate a business but it doesn t mean they have a business license. As far as going to the city hall you could do that to see if someone has a business license but I am not sure if they would tell you unless you have a reason for needing to know. I don t think they would provide you with a list of everyone who holds a business license and addresses or anything like that so your boss could solicit them for business. Why else would he need to know who all holds a business license? This is not something you can just go and look at their books or records and find for yourself.
