OK, so you can’t use a find SSN tool to dig up information on your new boyfriend or to check out that job applicant you just interviewed. But in certain cases, searching for a person’s Social Security number online is perfectly legal.
The next step in finding out who stole your Social Security number or who misused your personal data, is to file an ID Theft Complaint with the Federal Trade Commission (FTC). This government agency doesn’t bring criminal cases against identity thieves.
How do you find out what your social security number is? You should have been issued a social security card early in life, if you were born in the US. If you are an immigrant, you would receive it when you receive citizenship.
