Credit Card Lenders --= who uses which bureau and version?

[jwa77]

I am relatively certain this information is and has always been propietary--but it can be reverse-engineered by people who report approvals (or denials) and list what bureau that lender pulled.  Does such a list exist on here?

Here is one of them

A lot of times HP will dependent on where you live, so if you have specific card in mind, it's easier to share data points that way

Even the lenders who consistently pull same CRA have been known to HP a different one (such as Synch with EX), or Barclay doing EX SP in addition to TU HP. 

I would not put too much weight on any chart/list, as this is truly one of those YMMV situations.
