KNOW BEFORE YOU BUY

Local Illinois regulations

Illinois has specific telemarketing laws that businesses must comply with to avoid penalties.

Telemarketers must adhere to calling hours of 8 AM to 9 PM and comply with the Illinois Restricted Call Registry, which is integrated with the National Do Not Call Registry; consumer registrations do not expire and remain active unless the subscriber removes or changes their number.
The Illinois Telephone Solicitations Act (815 ILCS 413) outlines disclosure requirements and prohibited practices for all telephone solicitors operating in Illinois; while the Act governs solicitation conduct, Illinois does not impose a general state telemarketing license or registration requirement.
Knowing and willful violations carry fines of up to $1,000 for a first offense and $2,500 for subsequent offenses, with enforcement by the Illinois Commerce Commission, Attorney General, FTC, and FCC.

These regulations emphasize the need for businesses to adhere to state-specific rules when engaging in telemarketing within Illinois.
