If someone uses two social security number, is this a major crime? ?

Yes, they are both crimes. To use other Social Security Numbers to obtain money is a Federal Offense. Then to forge a signature is another Federal Offense, . So if you know who these are and you have proof, you need to let the Social Security Administration know. When you call them you will have to wait a long, long time to be able to speak to a clerk. You can also contact the Federal Marshal in your State, City or County. They will get right on it. All of us Americans work hard and pay into the Social Security Program. Why should we let some Low life take money from Americans? There is a Social Security Office in your City. Call them and make an appointment or just go there. They will keep you confidential, but they need to know who this s bag is. Do it and don't feel guilty for Protecting the America Social Security money.
