Scammers are saying your Social Security number (SSN) has been suspended because of suspicious activity, or because it’s been involved in a crime. Sometimes, the scammer wants you to confirm your SSN to reactivate it. Sometimes, he’ll say your bank account is about to be seized – but he’ll tell you what to do to keep it safe. (Often, that involves putting your money on gift cards and giving him the codes – which, of course, means that your money is gone.)
