Keep Your Social Security Number SafePosted: June 26, 2010
Keep your Social Security number’s last four digits secret. You are only legally required to give out your Social Security number (SSN) when applying for new financial accounts, to an employer or for governmental purposes. The last four digits combined with your name and address could be used to obtain a wealth of information.
Safety: Ask why a company would need your SSN — if you are not comfortable with the answer, seek an alternative company or use another means of ID.
