The Business Services Online Suite of Services allows organizations, businesses, individuals, employers, attorneys, non-attorneys representing Social Security claimants, and third-parties to exchange information with Social Security securely over the internet. You must register and create your own password to access Business Services Online.


On March 25, 2023, we are updating how you sign up for a Business Services Online (BSO) account for the following services:

  • Wage File Upload
  • W-2 Online
  • W-2C Online
  • AccuWage Online
  • Social Security Number Verification Service (SSNVS)

BSO users will need a separate Social Security online account, for example, a my Social Security account that was created before September 18, 2021, or have an existing Login.gov or ID.me account.

If you do not have a Social Security online account or a Login.gov or ID.me account, you will need to create one from our Social Security Sign in page. This is a new requirement to access BSO employer services.

Once the credentialing and authentication process has been completed, current BSO User ID(s) will be associated with your new credential.

We appreciate your patience as we continue to enhance our system.

The Complete Phone Registration option is provided to individuals who began their Business Services Online registration by phone and need to create a password.
