Very rarely NFCU will pull EX. If it’s blocked, they will move to TU. That’s likely what happened here.
I applied August 15th for a Platinum and they pulled EQ only. 15k CL and I live in Virginia.
Navy FCU has been known to do HP's on two bureau's quite a bit. This is usually because they have reason to suspect that something might only report on one location. Experian is the most common to be included most of the time.
Since your report is locked how did you end up finding out that they hit both?
No worries. I was just curious since I have not needed to use locks on my credit reports yet. My credit reports are naturally heavily monitored though so unlikely a unexpected line would show up.
