There shall be a single State-wide, toll-free telephone number established and maintained by the Department which all persons, whether or not mandated by law, may use to report suspected child abuse or neglect at any hour of the day or night, on any day of the week. Immediately upon receipt of such reports, the Department shall transmit the contents of the report, either orally or electronically, to the appropriate Child Protective Service Unit. Any other person may use the State-wide number to obtain assistance or information concerning the handling of child abuse and neglect cases.
Wherever the Statewide number is posted, there shall also be posted the following notice:
"Any person who knowingly transmits a false report to the Department commits the offense of disorderly conduct under subsection (a)(7) of Section 26-1 of the Criminal Code of 2012. A violation of this subsection is a Class 4 felony."
