Credit reporting. My birthday and previous addresses are listed in them, and if someone else has the same address now (old apartment), their name may show up in relation to me. Your life is not as private as you think it is.
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.
