What is the big concern about exposing my Social Security number?
These days, there is a big concern that identity thieves could use your Social Security number to pretend they are you to banks or financial institutions that offer loans or credit cards. Then, they can make charges to those credit cards or not pay back the loans, and disappear. The records will be in your name, so it will look like you did this, even though you didn’t even know about it. This can affect your future ability to get credit, such as to apply for a new credit card, a car loan, or a mortgage.
