20 ILCS 205/205-435: Badges.

The Director must authorize to each Inspector of the Department and to any other employee of the Department exercising the powers of a peace officer a distinct badge that, on its face, (i) clearly states that the badge is authorized by the Department and (ii) contains a unique identifying number. No other badge shall be authorized by the Department. Nothing in this Section prohibits the Director from issuing shields or other distinctive identification to employees performing security or regulatory duties who are not peace officers if the Director determines that a shield or distinctive identification is needed by the employee to carry out his or her responsibilities.
