A PIN and password are needed to file W-2s electronically. From the Registration link, you can also update registration information, change a password or deactivate a PIN.

A PIN is a personal ID, not a company ID. Each person who files W-2 reports electronically must have a PIN.



Wage reporting services

Social Security’s BSO system is for registered users only. Employers may use the service to:

  • Upload a wage report file formatted according to Social Security’s Magnetic Media Reporting and Electronic Filing specifications. This option is ideal for any size filer;
  • Complete up to 20 W-2s at one time right on your computer, electronically submit them to Social Security and print copies suitable for distribution to your employees;
  • View the current status of your previously submitted wage report; and
  • Tell us that you have received a resubmission notice.

Employers can verify names and Social Security numbers online


The Social Security Number Verification Service (SSNVS) matches your record of employee names and Social Security numbers with Social Security’s records before you prepare and submit W-2s. Making sure names and Social Security numbers entered on the W-2s match our records is important because unmatched records can result in additional processing costs for you and uncredited earnings for your employees. Uncredited earnings can affect future eligibility for (and amounts paid under) the Social Security retirement, disability and survivors program.For detailed instructions on registering and/or using SSNVS, get a copy of the SSNVS handbook at www.socialsecurity.gov/employer/ssnv.htm.
