Social Security Administration
What is Social Security?
Social Security is the foundation of economic security for millions of Americans—retirees, disabled persons, and families of retired, disabled or deceased workers.
How does Social Security work?
In the United States, employers and employees are required to pay Social Security taxes. The money raised from these taxes primarily goes to providing benefits for those who have reached retirement age or are otherwise currently eligible.
What is a Social Security Number?
The original and essential purpose of SSNs is to keep track of the money you put into the Social Security program so that you can get the benefits you're entitled to. The government needs lifelong, unique identity numbers to keep track of people's payments throughout an entire working life, no matter how often we move or change occupations or even change our names.
