Generally, for a new credit card account NFCU pulls information from Trans Union. (Although some members have reported Experian pulls as well...)
NFCU uses it's own scoring system to assign a numerical value to that information. "credit score".
It's not Fico 8 or Fico 9, it is an internal score based on their own scoring model.
I guess when the time comes, we will just cross our fingers for that second card! 🤣
...just be certain that time comes AFTER you've had the first card for at least 91 days AND three statements... otherwise, they'll auto deny.
