@donkort I have Verizon (closed and default at the moment) showing up on 2/3 CRBs.
Verizon was showing up on Experian long before I defaulted.
So, I wouldn't say they don't show up they do just not all of them. And, prior to this time on Verizon they hadn't shown on my CR.
I hadn't been on Verizon since 2012/2013 area when I went back on them in 2019 so reporting to the CBRs is new.
