State Information Data Exchange System (SIDES) E-Response

State Information Data Exchange System (SIDES) E-Response

Developed through a strategic partnership between the United States Department of Labor (USDOL) and state unemployment insurance (UI) agencies, the State Information Data Exchange System (SIDES) E-Response website offers employers and third-party administrators (TPAs) – free of charge – a secure, electronic, and nationally-standardized format in which they can easily respond to UI information requests, attach documentation when needed, and receive a date-stamped confirmation of receipt. Now, employers and TPAs in states implementing the SIDES E-Response website can adopt an electronic standardized format to anticipate better and supply the data needed for UI information requests and, in return, reduce follow-up phone calls and paper work, and streamline their UI response processes while saving time and money.

Before logging into the SIDES E-Response website, you will need the following credentials:

  • Federal Employer Identification Number (FEIN)
  • 14-digit State Employer Identification Number (SEIN), if used by requesting state.
  • Personal Identification Number (PIN)/Access Code (from the mailed notice of claim form)
