Amazon Marketplace is the sales channel through which third-party sellers offer products to consumers in Amazon's online stores. Sellers register, list their products and log in to Seller Central, Amazon's seller tool. The marketplace is offered as a hosted online service, and sellers reach shoppers in the stores that Amazon operates in several countries. Amazon presents the marketplace as a sales channel for sellers who want to launch their products in the Amazon store.
Amazon.com, Inc. is headquartered in Seattle, Washington, and listed on the Nasdaq, with no controlling shareholder named in the sources used. The seller pages are published by Amazon.com Services LLC, a US entity. Amazon operates stores worldwide, and the seller page does not state which legal entity runs each regional store. For a European organisation, the main sovereignty questions are US jurisdiction and where seller and buyer data is stored, which the seller documentation does not specify.
