How the EU Digital Services Act Affects Domain Marketplaces

The European Union’s Digital Services Act (DSA), which entered into force in November 2022 and became fully applicable to most online platforms by February 2024, represents one of the most ambitious regulatory frameworks ever enacted for digital services. Although much of the media attention has focused on how the DSA affects large social media networks and online retailers, its implications for domain marketplaces are both profound and far-reaching. As digital marketplaces that facilitate the purchase, sale, auction, or leasing of internet domain names, these platforms fall within the scope of the DSA’s layered obligations depending on their size, reach, and functionality. The DSA’s provisions touch on content moderation, transparency, user protections, intermediary liability, and algorithmic accountability, all of which intersect with the core business operations and legal responsibilities of domain marketplaces.

At the heart of the DSA is a risk-based approach that stratifies obligations according to the nature of the intermediary service. Domain marketplaces typically qualify as online platforms, and in some cases, very large online platforms (VLOPs), depending on whether they have more than 45 million monthly active users in the EU. Under Article 3 of the DSA, domain marketplaces may be considered hosting services when they store information provided by users—such as domain listings, seller profiles, and WHOIS records—on request. This classification subjects them to general obligations applicable to all hosting providers, including the need to act expeditiously upon receiving notice of illegal content and to establish notice-and-action mechanisms that are accessible, user-friendly, and transparent.

One of the most immediate effects of the DSA on domain marketplaces is the requirement to implement a structured and documented system for responding to notices of allegedly illegal domain listings. This is especially relevant in cases where domain names contain trademarks, defamatory content, or incite unlawful conduct. For example, if a user lists a domain such as “brandname-abuse.eu” for sale and the trademark owner notifies the platform that the listing violates intellectual property rights, the marketplace must not only act promptly to remove or disable access to the domain listing but also inform the notifier of the outcome. These procedures must be explained in the platform’s terms of service, and any moderation decisions must be logged with reasons provided to the affected user.

The DSA also introduces robust transparency obligations that affect how domain marketplaces disclose information about their content moderation practices and business models. Marketplaces must publish annual reports detailing the number of take-down requests received, the grounds for those requests, the average time to respond, and the outcomes. For domain marketplaces that use automated systems to detect or manage listings—such as filters that block offensive or infringing domain names—they must disclose the parameters of such systems and allow users to contest automated decisions. This has implications for platforms that employ algorithmic tools to scan for typo-squatted domains, offensive language, or geo-restricted terms that may be illegal in certain EU member states.

Moreover, the DSA requires that all online platforms ensure traceability of traders. This obligation, found in Article 30, mandates that platforms verify the identity of professional sellers before they are permitted to offer services. For domain marketplaces, this means implementing enhanced Know Your Customer (KYC) procedures to verify the identity, contact details, and possibly the legal status of sellers offering domains for sale. This requirement aims to prevent fraudulent or anonymous listings, especially in high-value domain sales where risks of money laundering, phishing, or IP infringement are high. Marketplaces must also display clear information about the trader’s identity to consumers when a domain is listed, ensuring accountability and empowering buyers to make informed decisions.

For marketplaces that reach the threshold of being designated as VLOPs, the DSA imposes even more stringent obligations. These include mandatory risk assessments related to the dissemination of illegal content and systemic risks to civic discourse, consumer protection, and intellectual property. VLOPs must also engage in independent audits, appoint compliance officers, and maintain real-time databases of ads shown on their platform. Although few domain marketplaces currently meet this threshold, the rapid expansion of the domain aftermarket and the global nature of these platforms mean that some may soon fall within this category. As a result, even platforms that are not yet VLOPs are beginning to adopt compliance mechanisms preemptively.

Intermediary liability protections under the DSA also affect domain marketplaces by codifying when they are, and are not, responsible for third-party content. Like its predecessor, the E-Commerce Directive, the DSA maintains that hosting providers are not liable for user-generated content unless they have actual knowledge of illegality and fail to act. However, the DSA elaborates on what constitutes “actual knowledge” and introduces a concept of “constructive knowledge” through repeated patterns of abuse or failure to enforce platform rules. This raises the stakes for domain marketplaces, especially those that host listings for domains with recurring infringement issues, such as typo-squatting or impersonation domains. Failure to act diligently can erode liability protections and expose platforms to enforcement action.

Cross-border enforcement is another feature of the DSA that impacts domain marketplaces operating across the EU. The law establishes a network of Digital Services Coordinators in each member state, along with the European Board for Digital Services, to oversee compliance and share information. Marketplaces can be investigated and sanctioned by regulators in any country where they provide services, not just the jurisdiction of incorporation. This means a marketplace based in Germany could face regulatory scrutiny from authorities in France or Spain if users in those countries are affected. Non-compliance can result in significant penalties—up to 6% of annual global turnover for serious violations.

The DSA also reinforces user rights through its provisions on internal complaint-handling and out-of-court dispute resolution. Domain sellers or buyers who are subject to moderation decisions, such as the removal of a domain listing or suspension of an account, must be given access to an internal review mechanism. If dissatisfied, they must also have access to certified external dispute resolution bodies, which the DSA mandates member states to establish or recognize. For domain investors and brokers, this creates a clear pathway to challenge adverse platform actions, while also imposing new administrative burdens on marketplaces to maintain fair, timely, and documented appeal systems.

Finally, the DSA encourages platforms to promote responsible online behavior, including protecting minors, preventing manipulative interfaces (so-called “dark patterns”), and supporting accessibility. While these provisions may appear tangential to domain sales, they become relevant in areas such as adult-oriented domain listings, auction mechanics that use countdown timers or deceptive prompts, and marketing practices that target vulnerable consumers. Marketplaces must review their user interface designs and onboarding processes to ensure they do not exploit users’ cognitive biases or breach the DSA’s fairness principles.

In conclusion, the EU Digital Services Act significantly reshapes the regulatory environment for domain marketplaces, imposing a multi-dimensional framework that touches nearly every aspect of platform operation. From content moderation and trader verification to transparency, liability, and cross-border enforcement, the DSA raises the compliance bar and introduces new legal exposure for operators in the domain name economy. Marketplaces that act proactively—by updating their terms of service, integrating compliance protocols, training staff, and investing in robust user verification and dispute resolution mechanisms—will be best positioned to navigate the DSA’s complexities and maintain trust with users and regulators alike. In the evolving legal landscape of the EU digital single market, the domain marketplace is no longer a legal gray zone but a regulated space subject to detailed, enforceable obligations.
