Social Security Numbers
A Social Security Number (SSN) is a unique, nine-digit identifier assigned to individuals by the U.S. government. It primarily serves to track an individual's earnings and determine eligibility for Social Security benefits. Employers use SSNs for tax purposes, and they are also often required for various services, like applying for loans or government benefits. While essential for various administrative functions, SSNs are sensitive personal information that should be protected to prevent identity theft. Overall, the SSN plays a crucial role in the U.S. social welfare system and personal financial identity.
