Greece Just Made Age Verification Mandatory for Everyone

Greece passed a law requiring all social media users to prove their age, banning anyone under 15 from platforms starting in 2027.

Greece's parliament has passed a landmark law that will require all social media users in the country to prove their age. According to reporting from TechRadar, the legislation bans children under the age of 15 from using these platforms and mandates that companies implement a robust age verification system for every user. The law is set to take effect on January 1, 2027, giving platforms a three-year window to develop and deploy the necessary technology. This move makes Greece one of the first European Union countries to enforce such a sweeping and universal requirement, shifting the burden of proof for age from user self-attestation to mandatory, platform-enforced verification.

The Greek government is reportedly promoting its own digital identity solution, the “Kids Wallet” app, as a preferred method for this verification. For developers, CTOs, and security teams, this detail is critical. It signals a move away from common but less reliable methods like credit card checks or self-declarations and toward integration with state-managed digital identity systems. This presents a significant engineering challenge. Platforms will need to build secure API integrations with government infrastructure, handle sensitive identity data in a privacy-preserving way, and design a user experience that is both seamless and resistant to fraud. The technical lift involves building complex identity management flows that can adapt to specific national standards, a far more involved process than simply adding a date-of-birth field to a sign-up form.

This legislation does not exist in a vacuum. It is part of a broader global trend of governments attempting to increase online child safety through regulation. Greece’s approach follows efforts in Australia to establish similar frameworks. Meanwhile, a similar law in France was struck down by its constitutional court, highlighting the legal and privacy-related hurdles these measures face. The United Kingdom is also developing its own rules under its wide-ranging Online Safety Act. For global technology companies, this creates a complex and fragmented compliance landscape. A verification system designed to integrate with Greece's digital wallet may not be compatible with the UK's eventual requirements, forcing companies to build and maintain multiple, localized solutions.

The practical takeaway for technology leaders is that mandatory age verification is rapidly moving from a theoretical policy debate to a concrete product and engineering requirement. The 2027 deadline provides a runway, but the necessary architectural decisions must be made soon. Teams operating in or expanding to Europe should begin evaluating third-party verification providers, exploring the feasibility of integrating with national digital ID systems, and auditing their security posture for handling a new class of highly sensitive user data. The key question to watch is whether the EU will eventually standardize an approach to age verification, or if the current patchwork of national laws will become the new normal for global platforms.

This law transforms age verification from a policy debate into a concrete engineering mandate. Development and security teams must now design, build, and secure systems to handle identity verification at scale, a significant technical challenge with major privacy and security implications for any platform operating in Europe.

The Greek law creates a new, costly compliance requirement for any platform with users in the EU. Companies face significant engineering costs, potential legal liability for non-compliance, and the risk of user friction or drop-off from verification processes. This sets a precedent that could be replicated across Europe.
