how to check if someone is using my child's social security number?
First, you need to check with the Social Security Administration once a year to make sure no one is using your child's SSN. Secondly, you need to check your child's credit report (free – Equifax -1-800-525-6285; Experian-1-888-397-3742; TransUnion-1-800-680-7289.) You can also report fraud to them.
