Adult content
In effectMissouri's requirement comes from an Attorney General rule (15 CSR 60-18) adopted under the Merchandising Practices Act, published May 7, 2025 and effective Nov 30, 2025. It requires sites where a substantial share of content is harmful to minors to use reasonable age verification. Five further bills were filed in the 2026 session to put the requirement in statute and expand it; those remain pending. Update: on July 9, 2026, Gov. Mike Kehoe signed House Bill 1839, putting the requirement into statute -- covering sites where more than one-third of content is sexual material, explicitly including social media, and allowing verification by digital ID, government ID, or transactional data. It moves Missouri's mandate from an AG rule to black-letter law.
