Social Security Number Verification Service (SSNVS) Handbook
- Submit names and Social Security numbers for verification online through our input screens and/or through the electronic file submission.
- Review your file for the correct formatting to ensure that the file is error-free—a properly formatted file will avoid rejection.
- Verify your entire payroll record before you file your W-2s through the SSNVS electronic file submission. You can zip (compress) your file. The transmission time required will be substantially reduced if the file is zipped.*
- Correct names and Social Security numbers allow us to properly credit your employees’ earnings records which will be important in determining their future Social Security benefits.
Note: Remember, while SSNVS is available to all employers and third-party submitters, it can only be used for wage reporting purposes ! It cannot be used for other services such as Forms 1040 and 1099.
