Missouri Children's Privacy Laws (2026)

No state kids-products law · current as of July 18, 2026

Missouri has no state-level kids-products privacy or age-assurance law as of July 18, 2026. That doesn't mean nothing applies: the federal COPPA baseline governs data collected from children under 13 in every state, and a product shipped nationwide still has to meet the strictest state rules elsewhere. See the full tracker map for the national picture.

Also on the books (out of scope): Missouri AG Age-Verification Rule, 15 CSR 60-18.010 et seq.: ADULT-CONTENT age-verification regulation under the MMPA (RSMo 407.020); adult sites must verify users are 18+; in force since Nov. 30, 2025.; HB 1839 / HCS HBs 1839, 2921 & 3015 (2026): 'Age Verification on Adult Websites'; codifies the AG's 15 CSR 60-18 age-gate (33% harmful-to-minors content threshold); SIGNED by Gov. Kehoe 2026-07-09, effective 2026-08-28. Stays out-of-scope per convention (adult-content AV, not a kids-product law).; HB 3393: Social Media Use by Minors (Rep. Don Mayhew) DIED and is not law. Its own vehicle (HCS HBs 3393 & 2392, the 'Megan Meier Act') last moved 2026-04-02 on an HCS Reported Do Pass. Its text was then amended into HCS HBs 1887, 2361, 1913, 2862 & 2321 as Sec. 407.3475 (HA 1 and HA 2, adopted 2026-04-14), which passed the House 145-3 on 2026-04-20 but died in Senate General Laws: final action was a CANCELLED hearing, recorded 2026-04-27 for a hearing that had been set for 2026-04-29, and the bill never reached Truly Agreed and Finally Passed. Missouri's constitutional cutoff for considering bills fell on 2026-05-15, after which it could not move. Sec. 407.3475 does not exist in the Revised Statutes; revisor.mo.gov returns its does-not-exist error for that section, and Chapter 407 jumps from 407.3405 to 407.3600. Verified 2026-07-30 against house.mo.gov bill actions and the Revisor. Note that search summarizers assert this bill became law; the official House record contradicts them. Out-of-scope mandates (like adult-content age-gates) are tracked separately and don't set this state's status.

Federal · COPPAapplies here too

Regardless of state law, COPPA governs personal information collected from children under 13: notice, verifiable parental consent, data minimization, and (under the 2025 amended Rule) limits on retention and third-party sharing.
