Age-verification laws have swept the world in recent years. These rules, also known as age assurance or age checks, often require websites that contain a certain (or any) amount of explicit content to confirm that users are over 18. 

But it’s not just checking a “yes or no” box anymore. Many of these laws require personal data, such as a photo of a government ID or a facial recognition scan, to access parts of the internet.

While the purported aim of these laws is to keep minors from seeing porn, experts have told Mashable for years that age verification doesn’t work for that intended purpose. This is because website companies based in other countries may not comply, or citizens may attempt to circumvent these laws using VPNs (or, in the case of the UK’s Online Safety Act, by using images of video game characters). Early research out of NYU has suggested that age verification doesn’t work, as well.

Experts also state the digital privacy and security issues that could arise from submitting so much personal information to various websites. One is identity theft, should bad actors obtain access to this data, such as through a phishing scam pretending to be a verification system for a porn site. Another is a lack of access to parts of the internet entirely if someone doesn’t have an ID, which could widen the digital divide.

Yet, these laws are spreading throughout the world. Here’s a breakdown of the states and countries with age verification laws (so far). 

United States

The United States is distinct in that age-verification laws have been implemented on a state-by-state basis, as opposed to a federal one. While you’re not able to access Pornhub in Virginia, for instance, you can drive up to Maryland and browse all you’d like. 

Since Louisiana enacted its age verification law in 2023, similar bills have popped up across the country. Then, in 2025, the Supreme Court ruled that these laws are constitutional, essentially ensuring that more states will implement them as well, experts told Mashable at the time.

States with enacted age verification laws as of this publication, according to the adult industry trade organization the Free Speech Coalition, are:

• Alabama

• Arizona

• Arkansas

• Florida

• Georgia

• Idaho

• Indiana

• Kansas

• Kentucky

• Louisiana

• Mississippi

• Missouri

• Montana

• Nebraska

• North Carolina

• North Dakota

• Ohio

• Oklahoma

• South Carolina

• South Dakota

• Tennessee

• Texas

• Utah

• Virginia

• Wyoming

United Kingdom

The Online Safety Act, which contains the UK’s age-verification clause, went into effect in July 2025. Sites and apps must use one of several methods to assure someone’s age, such as taking their banking information, matching a photo with an ID, or scanning their face. 

The UK’s communication regulatory agency, Ofcom, stated that it will fine up to  £18 million or 10 percent of qualifying worldwide revenue (whichever is greater) for sites that don’t comply. Since then, “SFW” sites, from dating apps to Spotify and YouTube, have or will implement age checks in the region (and others). Controversial sites 4chan and Kiwi Farms have sued Ofcom, stating they shouldn’t need to comply as they operate outside the UK.

France

France’s age verification law, which requires explicit sites to have a third-party system to confirm users’ ages, went into effect in June 2025. It also must be “double-blind,” meaning the porn site can’t know the visitors’ age, while the verification system can’t know the site the visitor is looking at.

Soon after it was enacted, though, the law was briefly suspended until it was deemed legal by EU law. But in July, France’s highest court — the Council of State — annulled the suspension. This caused back and forth with Pornhub, which initially blocked itself in the country, then reinstated itself during that period, only to block itself again after the law’s suspension was revoked. 

Italy

Starting November 12, Italy will enact age verification for pornographic sites. Last Friday, Italy’s communications agency, AGCOM, released a list of 45 websites that must implement age verification systems to continue functioning in the country, or receive a warning and fines up to 250,000 Euros. The list includes Pornhub and OnlyFans. 

AGCOM stated on its website that a certified independent third party must verify users’ ages, doing so in two steps (identification and authentication of the identified person) — and it has to happen every session. When dealing with an app, a separate app must age-verify like a digital ID wallet app.

Australia

This law looks a little different than that of other countries, but its purpose is the same. Australia’s age-verification law states that at the end of this year, people will have to verify their ages when logged into their Google or Microsoft accounts and using those search engines. These engines must have tools or settings like “safe search,” where explicit content must be filtered out entirely. The highest safety setting must be the default for account holders for whom the age assurance system indicates are likely children. 

If age assurance can’t be done, explicit material must be blurred. 

China

Pornography is currently illegal in China, so its age-verification systems also look different. The country has strict age restrictions for video games, livestreaming and video-sharing platforms, payment processors, and social media. Users must undergo Real Name Verification, which requires providing their name and ID number to access these services. Depending on the app, users may have to give more information too, such as their phone number, bank account, and a facial recognition scan.

This list will likely grow longer, and Mashable will update it when it does. Ofcom’s group director for online safety, Oliver Griffiths, told Mashable back in June that age verification for porn sites was a “global issue” and sought to instill global norms. It seems that’s well on the way.

UPDATE: Dec. 2, 2025, 11:49 a.m. EST The U.S. list has been updated to add Missouri.
