A Social Security number (SSN) is used to report your wages to the U.S. government and to determine eligibility for Social Security benefits. Social Security numbers do not represent permission to work, nor are they proof of US citizenship or permanent residence. Social Security numbers can be assigned to foreign workers who are authorized to work in the United States.
Your Social Security Number is an important identifying number and should be kept in a safe place to avoid identity theft. Please do not give out this number to unknown parties, especially over the phone or email.
