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.
Before logging into the SIDES E-Response website, you will need the following credentials:
- Federal Employer Identification Number (FEIN)
- 10-digit State Employer Identification Number (SEIN), if used by requesting state
- Personal Identification Number (PIN)/Access Code (from the mailed notice of claim form)
