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

State Information Data Exchange System (SIDES)

The State Information Data Exchange System (SIDES) is a simple tool to help employers respond to unemployment insurance requests quickly, easily, and accurately.

Why SIDES?
SIDES can significantly improve the UI information exchange process. This web-based system meets the unique needs of businesses large and small with these benefits:

  • Provides for timely responses, avoiding late penalty assessments
  • Helps ensure the proper decision on claimant eligibility
  • Reduces staff time, paper work, and postage costs
  • Reduces follow up requests and phone calls
  • Ensures protection of sensitive employer and claimant data
  • Provides an electronic, nationally standardized data format
  • Includes data checks to ensure the exchange of complete and valid information
  • Allows attachment of supporting documentation

SIDES E-Response and SIDES Web Services (See Comparison).

SIDES E-Response
SIDES E-Response provides an easy and efficient portal for electronically posting responses to information requests and is available FREE OF CHARGE to any Maryland employer with internet access. SIDES E-Response is for employers with a limited number of UI claims. If you use a Third-Party Administrator (TPA) to handle the processing of your employees’ UI claims or wage requests, please consult with the TPA prior to using SIDES E-Response.

Request for Separation Information and Earnings Verification Requests
ALL Maryland employers who respond to a Request for Separation Information or to an Earnings Verification Request using Maryland’s BEACON 2.0 system will automatically be redirected to SIDES E-Response if you have the following:

  • Active Maryland Account with a valid Maryland State Employer Account Number
  • Federal Employer Identification Number (FEIN)
  • Pending Request for Separation Information or
  • Pending Earnings Verification Request

Reply to a paper Request for Separation Information or Earnings Verification request directly via the SIDES E-Response website. The Internet Key/PIN provided on the Request for Separation Information and Earnings Verification Request forms will serve as the PIN/Access Code on the SIDES E-Response website.

SIDES Web Services
SIDES Web Services is for employers and TPAs who typically deal with a large volume of UI information requests. SIDES Web Services provides an automated, “computer-to-computer interface” between the employers’ and TPAs' IT systems and that of the state agency.
