Age Verification Laws and VPN Usage: What's Changing in the UK and US

What are these age verification laws, and why are they suddenly everywhere?

Over the past few years, two separate legal movements have converged on the same basic idea: that websites hosting adult content, and in some cases other categories of content, should have to confirm a visitor is actually an adult before showing it to them. In the United Kingdom, this arrived as part of a single, sweeping piece of legislation — the Online Safety Act 2023. In the United States, it has arrived piecemeal, as a growing list of individual state laws passed one legislature at a time, starting with Louisiana in 2022 and expanding to roughly two dozen states since.

Both movements are responding to the same underlying concern — that age gates built around a simple click-through checkbox ("I am 18 or older") do essentially nothing to stop a minor from accessing adult content — but they take meaningfully different legal approaches, cover different categories of platform, and carry different consequences for the sites that don't comply. This guide walks through what each actually requires, what changed and when, and addresses the question a lot of people are actually searching for: what an age verification law and VPN use together actually mean for someone who just wants to keep browsing the way they always have.

What does the UK's Online Safety Act actually require?

The Online Safety Act 2023 (OSA) is a broad piece of UK legislation regulating online platforms generally, and it created a regulator role for Ofcom — the UK's existing communications regulator — to write and enforce detailed codes of practice under the Act's framework. Two parts of the Act are most relevant to age verification specifically.

Part 5 applies to services whose primary purpose is to publish or display pornographic content. Providers in that category are required to use "highly effective age assurance" to ensure that children cannot normally access the content. Ofcom's published guidance treats a basic self-declaration checkbox as explicitly insufficient, and instead points providers toward methods like photo-ID matching, facial age estimation, mobile network operator age checks, credit card verification, or open banking-style checks that infer age from an existing financial account.

Separately, Part 3 of the Act creates duties for "user-to-user" services and search engines — a much larger category that includes social media platforms, forums, and other sites where users interact or where content is indexed — to protect children from a broader set of harmful content, which can include pornography but also self-harm, suicide, and certain violent content. Ofcom's Children's Codes, issued under Part 3, set out the steps these services need to take, which for platforms that host any material in the restricted categories can include implementing their own age assurance measures rather than a blanket age-based ban.

The practical result is that the OSA's age-check requirements reach further than just dedicated adult sites — a general-purpose platform that allows adult content to be posted, or that indexes it through search, can fall under the same underlying obligation to keep it away from users it can't verify as adults.

When did the UK's rules actually take effect, and what changed?

Ofcom's guidance on age assurance under Part 5 came into force in January 2025, with a compliance deadline that arrived in the following months. By mid-2025, sites falling under the pornography-specific duty were expected to have "highly effective age assurance" live, and Ofcom began compliance and enforcement activity against providers that hadn't implemented it.

The visible, on-the-ground effect was immediate and widely noticed: major adult sites operating in the UK began prompting UK visitors for ID upload, facial age estimation, or other verification before granting access, and a number of general platforms — including some social and discussion sites that host or link to adult material — rolled out their own UK-specific age gates around the same window. Some smaller or non-compliant sites instead chose to geo-block UK visitors entirely rather than build out an age-assurance system, which is part of why VPN interest in the UK rose sharply around the same period — a geo-block based purely on the visitor's apparent country is exactly the kind of restriction a VPN is designed to route around, even though an actual ID- or biometric-based age check is a different technical problem entirely.

It's worth being precise about what "took effect" means here: the OSA itself became law in 2023, but Ofcom's specific codes of practice — the documents that actually spell out what counts as "highly effective" and set enforceable deadlines — were phased in afterward, which is why the visible changes to site behavior landed later, in 2025, rather than at the moment the Act itself was passed.

Which US states have age verification laws, and what do they require?

Unlike the UK's single national framework, the US picture is a patchwork. There is no federal age verification law for adult content as of this writing; instead, individual states have passed their own versions, and the details vary by state even though the core idea is consistent. Louisiana's Act 440, effective January 2023, is generally considered the first of this current wave, requiring commercial sites where a substantial portion of content is "material harmful to minors" to perform reasonable age verification, most commonly by checking a government-issued ID or using a third-party age-verification service.

Since then, a growing list of states — including Utah, Texas, Virginia, Mississippi, Montana, Arkansas, North Carolina, Idaho, Kansas, Nebraska, Indiana, Oklahoma, South Carolina, and others — have passed broadly similar laws, generally targeting commercial websites where a defined percentage of content meets the state's legal standard for material harmful to minors. Most of these laws put the compliance obligation on the website operator, not the visitor, and many include a statutory damages or civil-liability mechanism that lets the state, or in some versions a parent, sue a noncompliant site rather than relying solely on criminal enforcement.

The specifics differ meaningfully between states — what percentage of content triggers the law, what counts as acceptable verification, whether there's a private right of action — so treating "US age verification law" as one uniform rule is inaccurate. A site's actual obligation depends on which state's law applies to it and, from a user's perspective, which state a site currently detects them as visiting from.

Not every state law has survived unchallenged, either. Several have faced First Amendment litigation from adult-industry trade groups and civil liberties organizations, with mixed results — some laws have been preliminarily blocked by federal courts, others have been allowed to take effect while litigation continues, and the legal landscape has kept shifting state by state rather than settling on one nationwide answer.

What did the Supreme Court decide in Free Speech Coalition v. Paxton?

The most significant single legal development in the US side of this story is the Supreme Court's ruling in Free Speech Coalition v. Paxton, a case challenging Texas's age verification law, HB 1181. The adult industry trade group behind the case argued that requiring ID-based age verification to view constitutionally protected adult content — content that is legal for adults to view — imposed an unconstitutional burden on adult speech, pointing to older Supreme Court precedent from the internet's early years that had struck down similar federal attempts to mandate age verification online.

In its 2025 ruling, the Court sided with Texas, upholding the state's ability to require age verification for access to online sexual content, and applying a more permissive standard of review than the strict scrutiny the challengers argued should apply. The majority reasoned that verifying age before granting access to content that is obscene as to minors — even though it's protected for adults — is a different, more limited burden than the broader content restrictions the Court had rejected in earlier internet-era cases, and that states have a legitimate interest in keeping that specific category of content away from minors that justifies a verification requirement.

The practical effect of the ruling is significant beyond Texas alone: it removes the strongest constitutional argument that had been used to challenge these laws in other states, and it's widely expected to accelerate both the survival of existing state laws in ongoing litigation and the passage of new ones in states that hadn't yet acted. It does not, on its own, create a single federal age verification standard — each state law still stands or falls on its own text — but it substantially narrows the legal path that had been used to block them.

Is using a VPN to get around an age verification law illegal?

This is the question at the center of most people's actual interest in age verification law and VPN use, and the honest answer is that it depends on what exactly "get around" means, and it's more nuanced than a flat yes or no. Under both the UK's Online Safety Act and the current wave of US state laws, the legal obligation to perform age verification is placed on the website or platform — not on the individual visitor. Ofcom's enforcement powers under the OSA target noncompliant service providers, with penalties that can include substantial fines and, in serious cases, measures to restrict a site's availability in the UK. None of the US state laws reviewed for this guide create a criminal or civil penalty aimed at an individual visitor simply for using a VPN, a different browser, or any other tool to access a site from an apparent location other than where they actually are.

That distinction — obligation on the platform, not the visitor — is the single most important legal fact in this entire topic, and it's the part that gets lost in a lot of online discussion. Nothing in the UK's Online Safety Act or in the state laws surveyed here makes it a crime for a person to use a VPN, including specifically to reach a site that geo-restricts UK or state-specific traffic. A VPN itself remains a perfectly legal, widely used tool for privacy, security, and remote work, entirely independent of this topic.

Where it gets more nuanced is that a handful of newer or amended state proposals have started including broader circumvention language — provisions aimed at tools or services marketed specifically as a way to bypass age verification requirements, rather than at VPN use in general. As of this writing, that kind of provision is the exception rather than the rule, and it targets circumvention services and their marketing, not an individual's private use of a general-purpose VPN for their own browsing. Because state legislation in this area is moving quickly, treat this as a live area to watch rather than a settled, permanent answer — what's true of the law today in a given state isn't guaranteed to still be true a year from now.

Who actually faces legal risk under these laws — platforms or users?

To put a finer point on the previous section: under both the UK and US frameworks covered here, the party facing enforcement risk is overwhelmingly the platform, not the person browsing it. In the UK, Ofcom's enforcement toolkit is aimed at service providers — the companies operating the sites — through fines, enforceable notices, and in the most serious cases, business disruption measures like requiring payment processors or advertisers to withdraw services from a noncompliant site. There is no OSA provision that fines or prosecutes an individual UK resident for using a VPN to access a site.

In the US, the state laws surveyed here generally create liability for the website operator — through state attorney general enforcement, statutory damages, or in some states a private right of action allowing individuals (often framed around parents) to sue a noncompliant site. Again, the visitor is not the target of the statute's liability provisions in the laws reviewed here.

This asymmetry is intentional, not an oversight: both legal approaches are built around regulating commercial publishers, which is a more legally and practically tractable target than trying to police what hundreds of millions of individual internet users do in their own browsers. It also mirrors how most other platform-regulation laws work — the obligation to comply sits with the business operating the service, not with each person using it.

Why did VPN usage spike after these laws took effect?

Multiple VPN providers, including Proton VPN, publicly reported a sharp, multi-day increase in UK sign-ups and app downloads in the days immediately following the July 2025 enforcement window for Ofcom's Part 5 age-assurance requirements. Similar, smaller spikes have been reported around individual state law effective dates in the US, particularly in states where a major adult platform chose to geo-block the entire state rather than build out state-specific age verification. We won't restate a specific percentage or ranking figure here as though it were a verified, current statistic — those numbers move quickly and come from each provider's own reporting rather than independent audit — but the direction and timing of the pattern, VPN interest rising sharply right around each law's effective date, has been consistent and widely reported across both the UK and US rollouts.

The behavioral logic is straightforward: for someone unwilling or unable to complete an ID-upload or facial-estimation check, and whose target site has chosen to block an entire country or state rather than build age assurance for it, a VPN offers an immediate, familiar workaround — appear to be connecting from somewhere the block doesn't apply. That said, it only actually works against a geographic block. It does nothing against a site that still requires ID or biometric verification for every visitor regardless of location, which is an important distinction covered in more detail below.

Does a VPN actually work to bypass an age verification check?

The honest answer is: sometimes, and it depends entirely on which verification method the site is using, not on the VPN itself. There are two very different things a site might be doing under the banner of "age verification," and a VPN interacts with them completely differently.

The first is a pure geo-block: the site has decided it's easier or cheaper to simply stop serving visitors from a jurisdiction with an age-verification requirement than to build and operate an age-assurance system for them. In this case, the site is checking your apparent location, typically via your IP address, and refusing service based on that alone. A VPN defeats this completely and reliably, because it changes exactly the signal the site is checking — your apparent IP-based location — and nothing else about the check depends on anything a VPN can't change.

The second is an actual age-assurance system: ID document upload, facial age estimation, a mobile carrier check, an open-banking-style check against an existing account, or a third-party age-verification service the site has integrated. None of these are location-based checks, so a VPN has essentially no effect on them — appearing to connect from a different country doesn't change what document you're asked to upload or what your face looks like to an estimation model. A site using this kind of system generally applies it to every visitor regardless of where they appear to be connecting from, specifically because "just block the jurisdictions with a legal requirement" isn't a viable long-term strategy once several major markets all pass similar laws around the same time.

In practice, a lot of what's driven VPN interest around this topic is the first category — sites that chose the geo-block route rather than building compliant age assurance — rather than any technical trick that defeats an actual ID or biometric check. As more platforms shift toward the second category over time, simply connecting through a VPN becomes less effective as a way around the requirement, because the requirement stops being tied to location at all.

How can you tell whether a site is geo-blocking you or actually verifying age?

In practice, it's usually obvious within a few seconds of hitting the block. A pure geo-block typically shows a static message — something like "this content isn't available in your country" or "this service is not offered in the UK" — with no request for any personal information, no camera prompt, and no document upload option at all; the site has simply decided not to serve your apparent region. An actual age-assurance flow, by contrast, asks you to do something: upload an ID, look into your camera for a facial estimate, log into a mobile carrier or banking account, or hand your details to a named third-party verification vendor whose branding often appears in the flow itself.

This distinction is the fastest way to predict whether a VPN will actually help in a given case. If what you're looking at is a flat "not available in your region" message, a VPN set to a country or state without the same restriction will typically resolve it immediately, because the site isn't checking anything beyond your apparent location. If what you're looking at is a request for a document, a camera capture, or a login to a linked account, switching your apparent location with a VPN won't change what's being asked of you, because the check isn't location-based in the first place — you'd still need to complete it, or decline and lose access, regardless of which country the site thinks you're in.

Some sites use a hybrid approach: full geo-block for a subset of jurisdictions where compliance costs outweigh the traffic from that market, combined with an actual age-assurance flow for larger markets where blocking entirely isn't commercially viable. For a UK or US visitor specifically, that means the same platform can behave completely differently depending on which country or state a VPN makes it think you're connecting from — one exit location might trigger a full block, another might trigger a document request, and a third might let you through without any check at all if that particular jurisdiction has no applicable law yet. None of that is a flaw in the VPN; it reflects how unevenly age verification law has actually been adopted across different countries and US states.

What age assurance methods are sites actually using, and how reliable are they?

"Age assurance" covers a range of technical approaches, and they vary substantially in how intrusive they are and what data they collect. Document-based verification asks for a government-issued ID, which is checked either by the platform directly or, more commonly, by a third-party age-verification vendor the platform integrates with; some of these vendors advertise that they verify age and then discard the document rather than retain it, though verifying that claim independently for any specific vendor is outside the scope of this guide. Facial age estimation uses a live camera capture and a model that estimates approximate age from facial features, without necessarily matching identity to a specific document. Some providers use account-linked signals instead — a mobile carrier confirming a subscriber is on an adult plan, or a bank or credit card confirming an account holder is an adult — which avoids uploading a fresh document but ties the check to an existing account relationship.

Each method carries different privacy tradeoffs, and this guide isn't going to rate one as objectively "best," since the right tradeoff depends on what someone is most concerned about — data retention, biometric collection, or linking browsing habits to a real identity via an account. What's consistent across all of them, though, is that they don't key off IP address or apparent location, which is exactly why a VPN, on its own, doesn't defeat any of them.

Are there risks beyond legality to using a VPN this way?

Even where using a VPN to route around a geo-block isn't illegal, it isn't automatically risk-free or consequence-free in every other sense. A platform's own terms of service can independently prohibit using a VPN to misrepresent your location to access content or features not intended for your region — that's a contractual matter between the user and the platform, enforceable through account suspension rather than through the age verification law itself, and it's a genuinely separate question from "is this legal."

There's also a practical risk worth naming plainly: a rise in demand for "get around age verification" tools has attracted low-quality and outright malicious free VPN apps that market themselves specifically around this use case, some of which have weak security practices, inject ads, or handle user data poorly. That risk has nothing to do with the legality of age verification laws and everything to do with choosing a reputable, established VPN provider rather than an unfamiliar app that surged in app-store rankings specifically around a law's effective date. Our guide to evaluating a VPN for privacy covers what to actually check — jurisdiction, logging policy, independent audits — before trusting any provider with your traffic.

Will these laws keep expanding to more sites and states?

Based on the trajectory so far, expansion looks more likely than contraction. The Supreme Court's ruling in Free Speech Coalition v. Paxton removed the strongest constitutional obstacle that had been used to challenge these laws, which reduces the legal risk for additional state legislatures considering similar bills and makes it more likely that states currently facing litigation over their own laws will see those laws upheld rather than struck down. In the UK, Ofcom's codes under the Online Safety Act are still being refined and expanded in phases, and the Act itself was written with room for additional codes of practice covering more categories of harm over time, not just the pornography-specific Part 5 duty.

We won't speculate about a specific future state count or a specific future UK enforcement action, since that would be exactly the kind of unverified prediction this guide is committed to avoiding — but the general direction, more jurisdictions adopting age-verification requirements rather than fewer, has been consistent for several years running, and there's no current indication of that trend reversing.

How does the UK's approach differ from the US's state-by-state approach?

The structural difference matters for anyone trying to understand how this affects them. The UK has one national law, one regulator (Ofcom), and one set of codes of practice that apply uniformly across the whole country — a site either complies with Ofcom's standard for the whole UK market or it doesn't. The US has no equivalent federal framework for this specific issue; instead, each state's law applies only within that state, with its own definition of covered content, its own verification standard, and its own enforcement mechanism. A site can be fully compliant in Texas and entirely unregulated in a state that hasn't passed a similar law, and a US resident's experience of these rules can change simply by which state a site thinks they're connecting from.

That fragmentation is also why the US picture is harder to summarize in a single sentence than the UK picture: "is a VPN affected by US age verification law" doesn't have one national answer, because there isn't one national law — the honest answer always depends on which state's law is actually in play for the specific site and the specific state a visitor is either in or is virtually appearing to be in.

What should parents know about VPNs and age verification?

For a parent, the most important thing to understand is that a VPN is a general privacy and security tool, not a tool built specifically to defeat age checks — but it can, incidentally, be used to route around a site's geo-based age block the same way it can be used for any other geographic restriction. If a family's concern is a child using a VPN specifically to reach adult content that's geo-blocked in their country or state, the more durable solution is generally device- or network-level parental controls and content filtering — tools designed specifically for that purpose — rather than relying on a platform's geo-block staying in place, since geo-blocks are exactly the kind of restriction a VPN was built to route around and are not a reliable child-safety measure on their own.

It's also worth knowing that many mainstream VPN providers, including several reviewed on this site, explicitly restrict their own service to adult account holders under their terms of service, and none of the four providers covered on this site market themselves as a tool for circumventing age verification law — they're general-purpose privacy and security tools whose incidental effect on a geo-block is a side effect of what a VPN fundamentally does, not their stated purpose.

What should an adult user know before using a VPN in this context?

If you're an adult who's run into a geo-block on a site you're legally entitled to view in your own jurisdiction, and you're considering a VPN as the practical workaround, a few points are worth keeping in mind. First, the legal exposure discussed throughout this guide sits overwhelmingly with the platform, not with you, under both the UK's Online Safety Act and the US state laws surveyed here — but that can vary by state, and state legislation in this space is changing quickly, so it's worth checking your specific state's current law rather than assuming it will always match what's described here. Second, a VPN only reliably works around a pure geo-block; it does nothing against an actual document- or biometric-based age check, so don't expect it to bypass every site's system. Third, choose a reputable, established provider rather than an unfamiliar app that surged specifically around a law's effective date — that's exactly the kind of moment low-quality or malicious apps try to capitalize on. Our NordVPN review, Proton VPN review, PureVPN review, and FastestVPN review lay out each provider's stated policies so you can weigh them against your own priorities.

It's also worth reading a platform's own terms of service before relying on a VPN to access it from an apparent location other than your real one — as covered above, that's a separate, contractual question from whether age verification law itself makes the VPN use illegal, and the two shouldn't be conflated.

Does a VPN protect your privacy during an age verification check itself?

This is a related but distinct question from bypassing a check, and it's worth addressing directly: if you do complete an age-assurance process — uploading an ID, doing a facial scan, or linking an account — a VPN encrypts your connection to the site and to the age-verification vendor it uses, which protects that traffic from being intercepted on the network in between. It does not change what data the site or its verification vendor collects, retains, or does with the document or biometric data you submit directly to them once the connection reaches its destination — that's governed by the vendor's own privacy policy and data-retention practices, not by your VPN. Anyone concerned specifically about what happens to an uploaded ID or a facial scan after submission should read the verification vendor's own privacy policy, not assume a VPN addresses that concern, since it addresses a different part of the picture — transit security, not what the recipient does with the data afterward.

What common misconceptions should you watch out for?

A few claims circulate repeatedly in discussions of this topic and are worth addressing directly.

• "Using a VPN to access an age-restricted site is illegal." Not accurate under the UK and US laws reviewed in this guide — the compliance obligation falls on the platform, not the individual visitor, in both frameworks as they currently stand.
• "A VPN defeats any age verification check." Not accurate — a VPN only changes your apparent location, which defeats a pure geo-block but has no effect on an ID, facial-estimation, or account-linked check that applies regardless of location.
• "The UK's law only applies to porn sites." Not the full picture — Part 5 targets pornography specifically, but Part 3's broader Children's Codes reach a wider set of user-to-user and search services that may host or index age-restricted material alongside other content.
• "All 50 US states have this kind of law now." Not accurate — roughly two dozen states have passed a version of it as of this writing, not all fifty, and the specific requirements vary meaningfully state by state.
• "The Supreme Court struck down age verification laws." The opposite — in Free Speech Coalition v. Paxton, the Court upheld Texas's law, which is broadly expected to strengthen rather than weaken the legal footing of similar state laws going forward.

The bottom line

Age verification law in both the UK and the US has moved from a marketing-page checkbox to a genuine, enforceable requirement in a fairly short window, and it has changed how a lot of sites operate for UK and US visitors. Under both frameworks, the legal duty to verify age sits with the platform, not the person browsing it, which is why using a VPN in this context isn't itself illegal under current UK or US federal law — though a small number of state proposals have started targeting circumvention services more specifically, and state law in this area is moving quickly enough that it's worth checking current rules for your own state rather than treating any general guide, including this one, as a permanent answer. What a VPN actually does in practice is narrower than a lot of the discussion around it suggests: it reliably defeats a pure geo-block, and it does essentially nothing against an ID- or biometric-based age check. As more platforms shift toward the second kind of system rather than the first, a VPN alone will matter less to this specific question over time — even though it remains, for entirely separate reasons, a legitimate and widely used tool for privacy and security online.
