<prompt> Human: So the other day I was verifying my personal information through a credit reporting agency and found that a stranger is listed as someone I have lived with and listed as the same address as me. Should I be worried? Is this person stealing my identity?  <response>: You didnt have any erroneous reports on your credit reports? Just the security questions were about this guy?Credit files are messy, dirty, data. They might think this guy is you, and this guy thinks youre some weirdo doing the same thing.Report it as incorrect personal information to the credit bureaus. Ive had family members personal information get tangled up with my information. Its odd that this is a stranger, but perhaps you had a similar address at some point in time or social security or birthdate. Really no way of knowing, and again, these are terrible messy data stacks untouched by humans most of the time. If this guy suddenly shows up as a co-creditor on a bunch of credit cards, its fraud.If this guy is just a security question, I wouldnt worry about it being fraud, but do report it.
