Social Security Administration
The Social Security Administration manages the Nation's social insurance program--consisting of retirement, survivors, and disability insurance programs--commonly known as Social Security; administers the Supplemental Security Income program for the aged, blind, and disabled; assigns Social Security numbers to U.S. citizens; and maintains earnings records for workers under their Social Security numbers.
