What type of documentation needs to be provided when updating the SSN on the employee's first day?

None. You will submit the SSN using the Personal Data Change Template on the employee's start date. Since we validate all DOB, SSN and Name Changes through the Social Security Number Verification System (SSNVS), no documentation needs to be attached.

Please Note: The person submitting the Personal Data Change Template is responsible for validating the documentation before completing the template. If we discover an error in the information that is contained on the template, we will cancel the template, explain why we are cancelling it and ask for you to re-verify any supporting documentation.
