As I look at this ( http://www.irs.gov/businesses/small/...=98011,00.html ), it seems that the same company may change its EIN a couple of times. How does the bank look at all these different EIN? How does the ... credit score (?) apply to all these different EIN? What I'm asking is this. Individual has only one Tax ID, and that's it; it makes sense for the individual to have credit score and what have you. But the company may change its EIN; how does the company's financial status get tracked?
