The proposed bill establishes new regulations regarding caller identification information in Florida. It creates two new sections in the Florida Statutes: Section 364.242, which prohibits the transmission of misleading or inaccurate caller identification information with the intent to defraud or cause harm, and mandates that telecommunications companies provide the originating telephone number and location for each call. Additionally, it requires these companies to block calls and text messages that contain manipulated caller ID information, with certain exceptions for law enforcement activities or court orders. Violations of this section could result in civil liability and penalties of up to $250,000.

The bill also introduces Section 364.243, which defines the "STIR/SHAKEN authentication framework" and mandates that telecommunications companies implement this framework by July 1, 2027, to verify caller identification information. Companies must certify to the Federal Communications Commission that their traffic is either verified by this framework or subject to an automated call mitigation program. The bill amends Section 365.176 to align with these new requirements, specifically stating that providers must block calls with manipulated caller ID information. The act is set to take effect on October 1, 2026.
