Interestingly, you actually never get signed up for these credit services until you get a credit card. So all the things people tell you “build credit” (eg: pay your bills on time, pay your rent, etc.) don’t actually “do” anything. There’s no credit score to attach to them, so they just go off into the ether. I built credit a bit late in life and it was a struggle to get started. At this point, I kind of wish I’d just avoided building credit altogether. I wouldn’t be in any of these systems.
