Northern Illinois Police and Fire Unit IDs

From The RadioReference Wiki

This page is constantly being updated and is a work in progress. If anyone has additional information to add to these pages, PLEASE add it!! But keep the formatting the same throughout the document if you do add anything. If there are questions regarding formatting or placement, please email me: and I should get back to you! Update: appears to be a dead email address(11/2022)

The basic formatting shall be as follows:

  • All TAGS that are headers or bullets, should have a space between the tag and the word or link brackets.
  • RED font shows that there is no unit numbering information available for that agency.
  • BLUE font will show that the agency is confirmed to be completed and no editing should take place.
  • Do not remove the LINKS as they are being taken care of by the moderators.
  • Do not ADD any LINKS that would create new pages.

This information has been gleaned from multiple sources, including Chicago Area Radio Monitoring Association (CARMA), listening to the scanner, and my own general knowledge. If there is a disagreement as to the accuracy of the information, please email me before changing it so that we can learn or compromise on the final outcome.
