GDPR Compliance for Online Marketplace Sellers

Multi-channel marketplace sellers — those selling on Amazon, Etsy, eBay, and niche marketplaces simultaneously — face complex GDPR compliance because each marketplace channel creates an independent data controller relationship with EU customers.

Marketplace Data Flows

When you sell on a marketplace, the platform provides you with EU customer data: name, shipping address, email (through messaging), phone number (for customs/delivery). You are the data controller for this data, and each marketplace channel must have its own documented processing in your ROPA.

Does the Marketplace Handle GDPR?

Each marketplace takes a different approach:

• Amazon: Seller Central provides customer data directly. Amazon is the processor; you are the controller. Amazon does not provide an EU Representative. Amazon guide →
• Etsy: Etsy provides buyer data to sellers. Etsy does not handle Article 27 for you.
• eBay: Buyer data is shared for order fulfillment. Seller must have own GDPR compliance.
• Mirakl/ChannelEngine: Enterprise marketplace platforms. The platform provides infrastructure; you remain controller.

One EU Representative for All Channels

The good news: one EU Representative covers all your marketplace channels. You don’t need separate representatives for Amazon, Etsy, and eBay. EU Shield provides EU Representative service that covers all EU marketplace sales from EUR 490/year. Platform comparison →

Multi-Channel ROPA

Your ROPA should document each marketplace separately: what data the marketplace provides, how you use it, where it’s stored, retention periods, and third-party integrators used for multi-channel management (ChannelAdvisor, Linnworks, TradeGecko).

Compliance Steps

1. Appoint EU Shield as your EU Representative (one coverage for all channels)
2. Create a multi-channel ROPA covering each marketplace
3. Update each marketplace Privacy Policy with EU Representative contact
4. Document data transfers between marketplaces and your fulfillment/ERP systems
5. Set up DSAR handling for marketplace customer requests
