Does Louisiana Ban Targeted Advertising to Minors on Social Media?

Yes. Since July 1, 2025, Louisiana's HB 577 has barred covered social media platforms from showing targeted advertisements to account holders they know are under 18, and from selling those minors' sensitive personal data. This is separate from Louisiana's broader Data Privacy Act, which applies to the general population and doesn't take effect until January 1, 2027.

Who's Covered

HB 577 applies to social media platforms with more than one million account holders worldwide that operate in Louisiana — a scale threshold that captures the major national platforms but excludes smaller or niche social apps that haven't reached that user count.

What's Actually Banned

Covered platforms can't target ads at a user when they know that user is under 18, and they can't sell that minor's sensitive personal data. The ban is specifically about targeting based on tracked behavior and data — it doesn't ban showing minors ads altogether, just ads selected using their personal data in the way targeted advertising normally works. A contextual ad shown to every visitor of a page, regardless of who they are, falls outside what the law restricts.

It Rode in on the Same Bill as an Age-Verification Law

HB 577 didn't just create the minors' ad restriction — it also moved up the effective date of Louisiana's SOCIAL Act, the state's related minors' social media age-verification law, from July 1, 2024 to July 1, 2025, aligning the two laws' start dates so both became enforceable the same day.

Two Different Louisiana Laws, Two Different Clocks

It's easy to conflate this with Louisiana's separate, broader Data Privacy Act, which covers all consumers — not just minors — and doesn't take effect until January 1, 2027. HB 577's minors-specific ad and data-sale ban had already been enforceable for roughly a year and a half by the time that broader law activates; they're not the same statute and don't share a start date, so checking only the 2027 date would leave you unaware this narrower restriction already applies.

Why This Matters for Advertisers and Platforms

If your campaigns run on a social platform that meets the one-million-account threshold and reaches Louisiana users, age-signal handling isn't optional: a platform that knowingly serves a targeted ad to a Louisiana minor, or sells that minor's sensitive data, is the party exposed to liability under this law. That exposure pushes platforms toward more conservative age-detection and ad-serving defaults for any account they can't confirm is 18 or older, which can affect how broadly an advertiser's targeting actually reaches on that platform.

Bottom Line

Don't assume Louisiana's advertising restrictions on minors are still pending — HB 577 has been enforceable since July 1, 2025, well before the state's broader privacy law arrives in 2027, so check your platform partners' minor-targeting safeguards now rather than waiting for a 2027 date that doesn't actually govern this restriction.
