US state age-verification laws

More than twenty US states now require some form of age verification to access online pornography, and — crucially — the Supreme Court has said that’s constitutional. This entry groups the state laws together because they rise and fall on the same legal foundation and raise the same privacy problem: to prove you’re an adult, you often have to hand your identity to a website or its vendor.

The Supreme Court changed the game

In Free Speech Coalition v. Paxton (decided June 27, 2025, 6–3), the Court upheld Texas’s H.B. 1181, which requires commercial sites publishing material “obscene to minors” to verify visitors are 18 or older. The majority applied intermediate scrutiny rather than the stricter standard earlier cases had used for online speech — a significant doctrinal shift that removed the main constitutional roadblock these laws had faced. Dissenters and civil-liberties groups warned the decision tramples free speech and undermines privacy, because age verification forces adults to identify themselves to access lawful content.

With the legal question resolved in states’ favor, the floodgates opened.

The privacy problem

However it’s implemented, age verification means an adult must prove their age to a website. In practice that means:

• Uploading a government ID, or
• Submitting to face-based age estimation, or
• A credit-card or database check.

Each creates a record that can link your identity to the specific content you viewed — exactly the kind of sensitive linkage that’s catastrophic if breached or subpoenaed. “We delete it immediately” is a promise, not a guarantee, and the incentives and track record of ad-tech and data brokers don’t inspire confidence.

The frontier: from websites to devices

The mandates are no longer confined to adult websites. Newer proposals push verification down to the operating system, app store, or device level, which would gate far more than pornography:

• Illinois passed House Bill 5511, a sweeping device-level age-gating framework reaching nearly all internet-enabled hardware, operating systems, and online services.
• At the federal level, the proposed SCREEN Act would impose age verification nationally.

Device- and store-level verification is a major escalation: it could mean proving your age to use general-purpose software, not just to visit one category of site.

Timeline

• 2023 — Texas enacts H.B. 1181; a wave of states follow.
• June 27, 2025 — Supreme Court upholds age verification in Free Speech Coalition v. Paxton (6–3).
• 2025–2026 — 20+ states now have age-verification laws in effect; more introduced.
• 2026 — Illinois passes HB 5511 (device-level age gating); the federal SCREEN Act is pending.

What it means for you

Expect more sites — and possibly your app store or phone — to demand proof of age. When you hit one, pay attention to how verification works and what’s retained; prefer methods that don’t store your ID. More broadly, this is the clearest example of a pattern to watch: a popular goal (protecting kids) driving mandates that require mass identity verification of adults, with the privacy costs treated as an afterthought.

Where to follow it: the EFF’s analysis of the Paxton decision (linked above) explains the stakes; state bill trackers follow the spread. We’ll update this grouped entry as major state laws and the federal SCREEN Act advance.
