This 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. The bill also outlines penalties for violations, including civil liability of up to $250,000 for telecommunications companies that fail to comply.

Furthermore, the bill introduces Section 364.243, which defines the STIR/SHAKEN authentication framework and mandates that all telecommunications companies implement this framework or an equivalent technology by July 1, 2027, to verify caller identification information. Companies must also certify their compliance with the Federal Communications Commission and provide documentation to the Attorney General or the commission upon request. The bill amends existing law to ensure that providers block calls with manipulated caller ID information and specifies that they may rely on information provided by the pooling administrator to determine the originating number. The act is set to take effect on October 1, 2026.
