If the apps are approved they show up as new accounts on all reports.

I've heard that several recent inquiries worry companies because they assume there's new accounts they're not seeing yet. The indication then is that new accounts show on all reports within a certain time.

I can understand why companies would be concerned about the amounts of lines of credit they are not yet seeing on reports.

It seems like they all rotate between Experian and Equifax most places. And sometimes business cards inquiries don't show.

But averaging 1 per month plays it safe. (Maybe too safe).
