Is it sufficient to include the manufacturer's address in the legal notice?

No. Artikel 19 GPSR expressly requires the manufacturer details on every individual product listing — that is, on the relevant product page, clearly and prominently. The legal notice does not fulfil this obligation because it does not link the information to a specific product. In practice, the manufacturer's name, trade name, or brand, a postal address, and an electronic contact address must appear in or directly alongside the product description. Many shop platforms now offer a dedicated field for this; anyone who leaves it empty risks a cease-and-desist letter for incomplete mandatory disclosures.
