It is EX for me and I do not even have an account with them. They have softed me four times this year, twice for pre-approved crap (one of which I applied for and was declined, I did not take the bait on trap two) and twice for an Account Review. (see my seperate thread: AMEX has mental probs).
I think I know what song plays in the building at AMEX HQ... It's by the Black Eyed Peas. The original version too, not the watered down "lets get it started".
I think AMEX is almost exclusively Experian. That is all I have ever seen.
just about but there are times when they'll pull TU and/or EQ in addition to EX upon app.
