How we tested
We called business verification APIs on lists of companies. We made one list for each country, US state, county, town or city. We made two lists for Israel. We have a list of charities in England and Wales too. We have a list of US transport companies and a list of US health care companies. We have a list of US investment advisers, a list of US nonprofits and a list of US banks. We have a list of US public companies too. We show how often each API is right about whether a company is registered, and how long each lookup takes.
