Ask HN: How to verify a business (users will register their business on my app)

I'm just curious how to verify a business that someone lists as their own. For example, if I'm a yoga instructor who runs a yoga studio, how can I verify that information? I'm having a hard time using google, maybe my search terms are wrong "how can I verify a business is legitimate" :(
