Employee Identification Number (EIN) vs. Social Security Number (SSN)

An EIN is issued by the IRS to identify a business entity for federal tax purposes. 7It is mandatory for most business structures, especially those with employees, or those operating as corporations or partnerships. In contrast, an SSN is issued by the Social Security Administration to individuals for tracking earnings, administering social security benefits, and identifying individuals for personal tax purposes.
