<prompt> Human: I was checking my credit report and it says that my oldest credit card is 17 years old even though I am currently 24? I am wondering does this have to do with my parents opening a credit line in my name? They are not the best parents and I honestly would not be surprised if they did such a thing. I do know they had really bad credit mainly my mom back then so I dont know if that would explain everything. The credit score simulator says that my credit score would drop if I were to close that account but I dont even see that credit line detailed anywhere, let alone be able to close it. Any ideas how I can find out what credit card this is?  <response>: your parents probably put you onto one of their existing cards as an authorised user.
