I just thought I'd post this in case anyone out there is wondering about this.
We have four accounts through GEMoney - JCP (mine, added DH as AU and it reported within a week. Added my brother and I got his card, but not reported at all).
Walmart (mine, added DH as AU and it reported within just a few days. Added my brother, I got his card, not reported at all).
CareCredit(mine, added DH as AU and it reported within a week. Added my brother, got his card, not reported at all).
Lowe's. (DH's. He added me at the store. Both reported within just a few days. We added my brother, got the card, not reported at all).
I think that it might be tricky to get an AU reporting to the bureaus that doesn't have the same last name and address w/ GEMoney.
I'll come back to this post if it does ever report to my brother's credit reports.
