Friendly reminders before accessing IMPACT!

  • To access IMPACT, you must create a user account in your name and pass identity proofing by visiting the above link and selecting “Register for New Account.” 
  •  The IMPACT user account belongs to the individual user and not to the company for which they may be employed. These accounts are associated with the IMPACT user’s identity, and it is prohibited to use someone else’s identity to access a State of Illinois system.
  • If you have not accessed IMPACT since March 2022 and know your legacy credentials (IMPACT User ID and Password), we recommend that you migrate your legacy account.
