There is nothing like this in the federal laws of the United States.

   The only similar requirement is for the .com registry which requires this info from all domain owners. People have been calling me at least since 1995 from this database. This has never bothered me. The worst thing that has happened is a business calling trying to sell something. However, if I were a woman I would not want my contact information to be public.

   Many other domain owners have chosen to enter false information into the .com whois database. From this desire for privacy, a number of services have been created that will enter their name, address, and phone number and forward any meaningful correspondence. If the imprint requirement persists in Germany, I imagine there will be companies that will protect your privacy for a small fee.

   I imagine there are a lot of other people who are as concerned as you are. What are they doing?

   I imagine this German law requires "an address" not necessarily your primary address? In the US there is the government-mandated postal system but there are also many private companies who provide postal addresses for a fee. Do you have those in Germany?

   Could you use you work address or a friend's address instead of your own?

   In the US, Google has given out free telephone numbers for their Grand Central system. Are there websites that give out free German phone numbers?
