Which of the following documents is used to verify identity and eligibility to work?

• A. Driver's license
• B. Passport
• C. I-9 verification documents
• D. Social Security card

Answer: (C)

When you’re testing how someone proves who they are and that they’re allowed to work, the process used is the I-9 verification. Employers complete Form I-9 for every new hire and check documents to confirm both identity and work authorization. These documents come from two sets: some establish identity, some establish work authorization, and some (List A) establish both. To satisfy the verification, an employee can present a single List A document or a combination of a List B document (identity) with a List C document (employment authorization).

That’s why the I-9 verification documents are the best answer: they represent the official set of documents used to verify who you are and that you’re allowed to work. A driver’s license shows identity but not work authorization on its own. A passport could demonstrate both identity and eligibility, but the question points to the established I-9 document category used in the verification process. A Social Security card alone indicates authorization but doesn’t establish identity by itself. Understanding this process helps explain why the I-9 verification documents are the correct reference for verifying both identity and eligibility to work.
