There's no real answer to that the same card company may pull Equifax in one region of the country and TU or EX in another part. I live in MN and most pull Equifax.
Do a google search for credit pulls data base.
USAA if you are military or former military.
Oregon community Credit Union
Sportsmans guide visa
Navy Federal Credit Union
NFCU has pulled from more than just Eq at the branch I am at in Eastern NC First Flight Credit Union ( small bank) very small, has only pulled from EQ
I would have said Nordstrom but I just checked my EQ report and they stopped softing it in April. Looks like they switched to EX.
Oh Wells Fargo pulled my Eq FICO, made me proud. Still stingy with the CL lol
