Key Documents Required for I-9 Verification

List A documents establish both identity and employment authorization, including a U.S. passport or Form I-551 Permanent Resident Card. List B documents prove identity only, such as a state-issued driver's license or ID card. List C documents demonstrate employment authorization, like a Social Security card or a birth certificate issued by a U.S. authority.

These documents include a valid driver's license, state identification card, or a U.S. school ID card with a photograph. Employers must ensure these documents are genuine and unexpired to confirm the individual's identity accurately.

These documents confirm that an individual is legally allowed to work in the United States without providing additional evidence of identity. Examples of List C documents include a Social Security card, a birth certificate, and a certification of report of birth issued by the Department of State.
