Illinois – Effective immediately, in response to the Illinois Supreme Court amended rule 138, the Commission will no longer collect Social Security numbers. The Social Security field has been eliminated from the application and settlement contract forms. The Commission asks that you do not enter the number on existing forms, and update your electronic forms. See http://www.iwcc.il.gov/forms.htm#CM
The Commission will request the SSN in those limited circumstances where the information is necessary, and only then at such time as necessary, e.g., to process payment from the Rate Adjustment Fund or Injured Workers Benefit Fund.
The Commission will also remove the numbers from existing files upon request. Email Kim Janas at kimberly.janas@illinois.gov.
