<prompt> Human: Hi all, a bit of back story, I just recently turned 18 on June 17 and I am certainly not ready to adult yet. I do have a job and make about 1,000 a month. So I was at American eagle shopping for some work uniform stuff and when I get up to the counter I am coerced into signing up for some kind of rewards card for 15 off! Sounds too good to be true. So I go through the process and became a little suspicious after I was prompted to put in my SSN. Few minutes go by and BAM Im signed up for a credit card. I called my mom explaining what happened and she seems worried. If I were to call and cancel the card before it is ever mailed in and activated could it hurt my credit score? I literally didnt know any better. Please send any helpful insight my way. Thank you. Edit: Worth noting that I have no prior credit history. Edit 2: Could the application be declined since I have no credit history? That would definitely hurt my credit right?  <response>: I am coerced into signing up No, you agreed to sign up. If I were to call and cancel the card before it is ever mailed in and activated could it hurt my credit score?Too late for that. You have the hard pull and approval. It would be smarter to keep it. If you dont trust yourself, ensure its paid off and has no maintenance fees, and then cut the card up but dont close it.Just having it will do FAR more good to your credit than the hard pull did to hurt it.
