What database are you referring to? Is there an international database for all businesses registered in every single country that everyone universally signs up for when they incorporate?
Every nation has its own. Nations that want to make their citizens safer when surfing the web could open up a standard API to make such automated queries
Businesses usually have domain names just like they have physical addresses.
If the database were to include the domain names we could make automatic checks to give the user more assurances.
Your reply is mind boggling and totally foreign to the topic.
