The State Information Data Exchange System (SIDES) was developed through a strategic partnership between the United States Department of Labor (USDOL) and state unemployment insurance (UI) agencies to provide employers and TPAs the ability to respond quickly and accurately to UI information requests electronically.

SIDES was designed to alleviate the challenges associated with responding to paper-based unemployment compensation requests.

Introduction to SIDES

SIDES and SIDES E-Response

There are two ways to connect depending on your specific needs. E-Response is a free of charge website for employers with a limited number of UC claims throughout the year. There is no programming needed.

For large and multi-state employers as well as TPAs, a computer-to-computer interface may be more appropriate as it allows employer to customize their system to interface with SIDES.
