Just doesn't seem right. When did I authorize that? If I'm only receiving UPS packages (where the sender has already paid UPS) why does my own creditworthiness matter?
I don't think it's credit worthiness as much as just verifying your identity by asking deeply personal questions about stuff they wouldn't otherwise know. How would UPS really know if the address you provided is right? They're leaning on credit companies who make a business on keeping super accurate records of our personal lives.
