One of my AU on my account is only 17 years old now, his name on the card doesn't match his ss number meaning the card has a nickname on it vs his real legal name if that should make a difference which i don't think does, now my other hunch is because hes 17yrs old which is the reason when i try to make his own login so he can see the spending he does and save offers to his own login i get the error "The Social Security Number entered for Additional Card Member is invalid", curios to know if anyone had luck adding an AU who's under 18 yrs old?
TIA
