Guaranteed Business Credit

Hello

How do I know if my credit card company are personally guaranteed? I do not have copies of original applications and I do not want to call the cards to use (because it can have a negative impact me). Is there something in the Terms and Conditions of cards that I should look?

Your business is a corporation? Is there a D & B Rating?

Otherwise, I guess you have personally guaranteed these credit cards.

Yes business is a corporation and I remember checking that out of the application. Question is what I know for sure without asking people to credit card service cust suspicious questions?
