This system makes it impossible to receive mail for friends and family. I'm the mailing address for a transigent family member so I have to put his name on our box, in addition to mine, my wife's, and her unmarried name.
I've had mail returned because of a name misspelling or illegible handwriting. But a postcode, street number and name, and apt/box # will always hit the mark.
Every house has a number and the name of every resident on the bell and mailbox. Typos are normally ignored by the competent, but sometimes lazy postman.
In the situation, that you are new and your name is not yet listed the address is following.
Henry Schuhmacher ( bei Friedrich Werner )
23562 Lübeck
Ratzeburger Allee 85
If the letter cant be delivered and the letter has consignor, it gets back. No magic, no real privacy.
In practice it worked perfectly well for me for more than two years living in shared flats in different places in Germany to give out only c/o (bei) addresses to anyone I ordered or corresponded with, I'm not aware of anything that got lost despite not having my name on the doorbell and post box.
You could even invent a name put that on the door and still c/o yourself, I guess that still would work. The only people who annually enter rental flats are normally the "Heizungsableser" people (heating consumption read out) and even they go floor by floor and not by name first.
