What are the most common reasons for mismatches?

Mismatches can happen even if the employee is authorized to work. Common causes include:

• Social Security number (SSN) doesn’t match the U.S. Social Security Administration (SSA) records.
• Name or immigration/citizenship status changes not reported to the U.S. Social Security Administration (SSA) or the U.S. Department of Homeland Security (DHS).
• Data entry errors (e.g., typos when entering info into I-9/E-Verify).
