What is SIDES? - State Information Data Exchange - Unemployment Insurance

Developed through a strategic partnership between the U.S. Department of Labor (USDOL) and state unemployment insurance agencies, the State Information Data Exchange System (SIDES) is an electronic tool to help employers respond to state unemployment insurance (UI) requests quickly, easily, and accurately.

There are two aspects of SIDES - SIDES for TPAs (Third Party Administrators) or large employers and SIDES E-Response. SIDES for TPAs and SIDES E-Response offer employers a secure, electronic and nationally-standardized format to better anticipate and supply the data needed to respond to UI information requests, reduce follow-up phone calls and streamline UI response processes. Both are web-based systems designed to meet the unique needs of businesses large and small. For employers and third party administrators (TPAs) that handle a large volume of UI information requests, SIDES provides an automated, “computer-to-computer interface” between employers’ and TPA’s IT systems and state agency networks. For employers with a limited number of UI claims, the SIDES E-Response website provides an easy and efficient “web-based reporting portal” for electronically posting responses to information requests from state UI agencies. SIDES E-Response is available in Maryland to any employer or TPA with internet access.
