An official source guide for online platforms that let consumers in the EU conclude distance contracts with traders.
Use it to structure seller onboarding, reliability checks, product listing fields, consumer disclosures, retention rules, and workflow evidence under DSA Articles 30-32.
DSA traceability governs marketplace onboarding and listing controls for covered trader offers. Article 30 applies to providers of online platforms that allow consumers to conclude distance contracts with a trader for products or services offered to consumers located in the Union. The practical test is whether the marketplace can collect the required trader data before access, assess whether it is reliable and complete, display the consumer-facing fields at the point where the product or service appears, store the file securely, and suspend marketplace access when required information is missing or not corrected.
Start with the service model. The DSA marketplace traceability duties sit in the section for providers of online platforms that allow consumers to conclude distance contracts with traders. A marketplace should document which storefronts, apps, booking flows, promoted listings, brand-sponsored offers, and third-party seller journeys let EU consumers contract with a .
Do not treat every platform feature as a -traceability feature. Community posts, search results, advertising services, hosting infrastructure, and content moderation workflows can trigger other DSA duties, but this guide concerns trader onboarding and product or service offers made through an online marketplace.
Document the seller-status test as well as the platform flow. A acts for purposes related to trade, business, craft, or profession, including through a representative; an individual making an occasional private sale is not necessarily a trader. If the facts are borderline, retain the facts and legal basis used for the decision and reassess when the seller's activity changes.

A covered marketplace should not allow a to use the platform to promote messages on products or services, or to offer products or services to EU consumers, until it has obtained the Article 30 trader information where applicable. The onboarding flow should block publication until all required fields are either completed or marked not applicable with a reason.
The transitional collection period for traders already using a marketplace on 17 February 2024 ended on 17 February 2025. A marketplace that still lacks required information for a legacy should not treat that deadline as open: request the missing information and suspend the trader's EU consumer offers if the trader does not fully comply.
The required file is concrete: name, address, telephone number and email; an identity document copy or electronic identification; payment account details; trade-register or equivalent public-register details when the trader is registered; and a trader self-certification to offer only products or services that comply with applicable Union law.

Article 30 does not make the marketplace a guarantor of every statement. It requires best efforts to assess whether the required trader information is reliable and complete before access, using freely accessible official databases or interfaces made available by a Member State or the Union, or supporting documents from reliable sources requested from the trader.
Build a correction workflow for stale, inconsistent, or suspicious records. When the marketplace has sufficient indications or reason to believe a required item is inaccurate, incomplete, or not up to date, it should ask the to remedy the issue without delay or within the applicable legal period. If the trader does not correct or complete the information, the marketplace should suspend the service for offers to EU consumers until the request is fully complied with.

Article 31 turns traceability into product design. A marketplace interface should allow traders to provide pre-contractual information, compliance information, and product safety information required by applicable Union law. It should also let traders identify the product or service clearly, show signs identifying the such as a trademark, symbol or logo, and provide applicable labelling and marking information.
Before allowing the offer, the marketplace should make best efforts to assess whether the has provided the Article 31 information. After publication, it should make reasonable efforts to randomly check official, freely accessible, machine-readable databases or interfaces to see whether offered products or services have been identified as illegal.

Article 31 requires marketplace interface design for trader compliance information and reasonable random checks against official illegal-product or illegal-service sources.
Compliance by design

Article 30 requires the marketplace to make selected information available to recipients in a clear, easily accessible, and comprehensible way. At minimum, the product or service interface should expose the trader name and contact details, trade-register information where applicable, and the trader self-certification commitment that only compliant products or services will be offered.
If the marketplace becomes aware that an illegal product or service has been offered to EU consumers through its service, Article 32 adds a consumer information workflow. Where contact details are available, consumers who purchased the illegal product or service in the six months before the marketplace became aware should be told that the product or service is illegal, the identity of the , and relevant means of redress. Where contact details are not available for all affected consumers, the marketplace should make that information publicly available and easily accessible on its interface.

traceability records contain identification, contact, payment, register, and self-certification data. Article 30 requires secure storage during the contractual relationship and for six months after it ends, followed by deletion. Disclosure to third parties should occur only where required under applicable law, including DSA information orders or orders from competent authorities or the Commission.
A useful evidence file should prove both the legal duty and the operational control. It should show the 's lifecycle from onboarding through verification, live display, random product or service checks, correction requests, suspension or reinstatement, consumer notices for illegal offers, and deletion after the retention period.
Article 30 requires, where applicable, contact details, identity or eID evidence, payment account details, trade-register details, and a self-certification that the trader will offer only products or services complying with applicable Union law.
