In Germany my family name goes on the door bell name tag (
Türklingel Namensschilder or
Klingelschilder) and mailboxes name tag (
Briefkasten Namensschild) for identification purposes and for the correct handling of the post office mail. In my country there are multiple family names (some from the mothers family and some from the father family) and not only one, so I might be receiving mail using abbreviated forms or just the name followed by the last family name.
Is there any rules/laws regarding the naming system on these tags? If I do abbreviate will be postal worker allowed to place in mail for me? If me and my wife have the same surnames[last names] should I place the standard abbreviated name and family name separated by slashes to denote different persons regardless of the family name being the same?
