What form should an employee complete to obtain a new or duplicate Social Security card?

The form that an employee should complete to obtain a new or duplicate Social Security card is the SS-5. This form is specifically designated for applications related to Social Security cards, whether for a new card or a replacement. It requires the individual to provide personal information including their name, Social Security number (if applicable), and proof of identity, which is essential for the Social Security Administration to process the request accurately.

The other forms listed serve different purposes. For instance, the W-4 is used by employees to indicate their tax withholding preferences to their employer. The I-9 is the Employment Eligibility Verification form that employers must complete to verify an employee’s identity and eligibility to work in the United States. The I-766, known as the Employment Authorization Document, is issued to foreign nationals who are temporarily in the U.S. and allows them to work. Therefore, the SS-5 is the appropriate choice when an individual seeks to obtain or replace their Social Security card.
