Social Security No:
If you are an outside contractor, use your SSN or your company's EIN. If these numbers are not successful, contact the company's HR department to request the unique number assigned to you in lieu of a normal SSN.
Home Zip Code:
You must match your residence zip code on file with your employer. If you have recently moved, try using the zip code associated with your old residence.
Birth Date:
If you are an outside contractor, it is possible that the company has not used your actual date of birth in this field. Contact the HR department to determine the date that is listed in your user records.
