Switzerland
Under Art. 3(1)(s) of the Federal Act against Unfair Competition, anyone offering goods, works or services in e-commerce acts unfairly if they do not inform clearly and fully about their identity and contact address, including email. Order-related duties come on top: information on the technical steps to conclude a contract, ways to correct input errors and immediate electronic order confirmation. For companies, company name, legal form and seat belong to it; many also state the UID.
Germany
Since May 2024, section 5 DDG governs general information duties. Required are, among others, name and address, for legal entities legal form and authorised representatives, details for fast electronic contact including email, register entry and number, and where applicable VAT ID and supervisory authority. Missing information is frequently the subject of warning letters in Germany.
