Missouri Age Verification Laws Now Live: What Businesses and Consumers Must Know

Missouri's new age verification laws are now active. Learn what businesses and consumers need to know about compliance, enforcement, and verification options.

Missouri's age verification laws are now live, affecting retailers, online sellers, and venues that sell age-restricted products and services. Whether you sell tobacco, vaping products, alcohol, or adult content, understanding the new rules and how to comply will help you avoid fines, license actions, and operational delays.

What the law means: At its core, the Missouri age verification law requires businesses to confirm a buyer’s age before completing a sale of restricted items. This applies to both in-person and online transactions. Retailers must adopt reasonable verification methods — from manual ID checks to digital ID scanning or third-party age verification services. Online sellers should implement effective age gates and verification workflows to reduce the risk of unlawful sales.

Who is affected: The law targets any business, platform, or individual selling age-restricted goods in Missouri. Brick-and-mortar stores, e-commerce sites, delivery services, and marketplace platforms should evaluate their current age verification practices to ensure compliance. Staff training and updated point-of-sale (POS) procedures are essential for retail locations.

Compliance tips: Start by auditing how you verify age today. For physical stores, require government-issued photo ID checks for younger-appearing customers and adopt ID-scanning technology where practical. For websites, use multi-step age gates, document verification, or third-party identity verification tools that balance user experience and privacy. Update terms of service and privacy policies to explain how you collect and store verification data, and ensure that storage practices comply with state and federal privacy rules.

Enforcement and penalties: Enforcement mechanisms vary, but businesses that fail to comply may face fines, license suspensions, and other administrative penalties. Regularly review state guidance and industry best practices to stay current with enforcement priorities.

Next steps: Train employees, update POS and website flows, and consult with legal counsel or compliance experts if you’re unsure how the law applies to your operations. Consider a phased approach: immediate changes for obvious high-risk sales, followed by integration of technological solutions for long-term compliance.

Missouri’s new age verification law raises the bar for responsible selling. Proactive steps now will protect your business and help keep age-restricted products out of the hands of minors. For specific legal advice, contact a qualified attorney familiar with Missouri regulatory requirements.
