Utah's Online Age Verification Amendments, formally Senate Bill 73, take effect on May 6, making the state the first in the U.S. to explicitly target VPN use as part of age verification legislation.
Signed by Governor Spencer Cox on March 19, the controversial law establishes that a user is considered to be accessing a website from Utah if they are physically located there, regardless of whether they use a VPN or proxy to mask their IP address. It also prohibits covered websites from sharing instructions on how to use a VPN to bypass age checks.
NordVPN has called the law an "unresolvable compliance paradox" and a "liability trap," arguing that it holds websites responsible for identifying users whose tools are specifically designed to be unidentifiable. The EFF warned that the legal risk could push sites to either ban all known VPN IPs or mandate age verification for every visitor globally.

The law is also technically flawed, given that it assumes that a web provider can reliably detect VPN traffic and determine a user’s true physical location — they can’t. IP reputation databases such as MaxMind and IP2Proxy can flag traffic from known datacenter IP ranges, but commercial VPN providers rotate addresses constantly, and residential VPN endpoints are largely indistinguishable from standard home connections. Autonomous System Number analysis can catch traffic originating from datacenter networks, but can’t identify a personal WireGuard tunnel running on a cloud VPS, for example, which routes through the same infrastructure as ordinary web hosting.
The only detection method that reliably identifies VPN protocol signatures is deep packet inspection, which analyzes traffic at the network level, not system- or app-level. China's Great Firewall and Russia's TSPU system deploy DPI via ISPs, but a website operator can’t because it requires access to network infrastructure that sits between the user and the server, not on the server itself.
Meanwhile, setting up a personal WireGuard instance on any major cloud provider takes minutes, meaning the law will be more likely to negatively impact non-technical users who rely on commercial VPN services for legitimate privacy: journalists, people living under authoritarian regimes, political dissidents, and abuse survivors, among others.
Utah isn’t alone in trying to legislate the impossible into being. In the UK, the House of Lords — Parliament’s secondary chamber — voted 207-159 in January to ban VPN services for under 18s, with those amendments now due to be debated in the House of Commons. VPN use jumped by more than 1,400% on the first day of age verification enforcement in July last year. Meanwhile, France’s digital affairs minister, Anne Le Hénanff, has said that VPNs are “next on my list.” Wisconsin considered similar VPN provisions earlier this year but scrapped them due to heavy backlash.
To date, the only countries that have made progress in blocking VPN traffic with some success are authoritarian regimes with ISP-level surveillance.
