Social Security Card
According to the Social Security Administration (SSA), "Social Security numbers are generally assigned to people who are authorized to work in the United States. Social Security numbers are used to report your wages to the government and to determine eligibility for Social Security benefits. Social Security will not assign you a number just to enroll in a college or school."
