MO HB1839

Websites where more than one-third of content is sexual material harmful to minors must use third-party age verification to confirm users are 18 or older before granting access

Age verification methods include digital identification, government-issued ID, or commercial systems using public/private transactional data (mortgage, education, employment records)

Third-party age verification providers are prohibited from retaining any identifying information about users

Internet service providers, search engines, and cloud service providers are exempt from liability for merely providing access to such websites

Civil penalties include $10,000 per day of operating without age verification, $10,000 per instance of retaining user information, and up to $250,000 if minors access harmful material; enforcement is by the Missouri Attorney General
