Incorrect Addresses Could Indicate Theft
If you spot the wrong address on your credit report, i.e. an address where you never lived, follow up on the address. It could be a sign of fraud or identity theft. You're entitled to an accurate credit report, so dispute the address with the credit bureau to have it removed. It's also a good idea to read through every entry on your credit report to be sure they're all accounts that you opened. Read through the list of inquiries on your credit report and contact the credit bureau if there are inquiries from companies you don't recognize. Note that odd addresses can end up on your credit report if you share an account with someone who's moved around.
Could Moving Alot Get You Denied?
Lenders could use the addresses on your credit report to make a lending decision about you. For example, a lender may check your credit report and interpret several different addresses as instability.
