The Social Security Administration administers retirement, disability, survivor and family benefits, and enrolls individuals in Medicare. It also provides Social Security numbers, handles financial transactions and determines eligibility for certain government services.
Social Security Disability Insurance and Supplemental Security Income programs provide assistance to people who meet eligibility requirements for disability. The SSDI program pays benefits to disabled individuals who have worked long enough and paid Social Security taxes on their earnings. The SSI program pays benefits to adults and children who meet eligibility requirements for a qualifying disability and have limited income and resources.
