The State Information Data Exchange System (SIDES) E-Response website is a powerful tool developed through a partnership between the United States Department of Labor (USDOL) and state unemployment insurance (UI) agencies. This free, secure platform offers employers and third-party administrators (TPAs) a streamlined, standardized way to respond to UI information requests. With SIDES E-Response, you can easily attach necessary documentation and receive a date-stamped confirmation of receipt.
Before accessing the SIDES E-Response website, make sure you have the following credentials ready:
- Federal Employer Identification Number (FEIN)
- 10-digit State Employer Identification Number (SEIN), if required by the requesting state
- Personal Identification Number (PIN) or Access Code from the mailed notice of claim form
