Buyers ask me this one a lot — usually right after they’ve spent twenty minutes Googling tradeline companies and aren’t sure if the whole thing is legitimate. The short answer: yes, you can pay to be added as an authorized user on someone else’s credit card. That’s actually the entire business model I run at kindoflost.com.
But there’s a longer answer worth reading before you spend money, because not all AU tradelines are the same, and a few details can make the difference between a purchase that moves your score and one that doesn’t.
