Legal Notice Requirement (Impressum)
The legal notice requirement (Impressum) obliges website operators with a commercial offering to make certain mandatory details easy to find and permanently available: name, address, a means of contact and, for companies, the commercial register number and VAT ID as well.
In practice
A legally sound Impressum must be reachable from every subpage in no more than two clicks, usually via a footer link. Missing or incomplete legal notice details are among the most common website errors and among the easiest targets for cease-and-desist warnings.
