changing address

I have recently changed address in zurich... I am registered as a C/o in the new place and the mail box doesnt bear my name, but that of the person whose house it is.

Should it be a problem for mail to reach me?

Coz when I went to Die post a week after making a change in address, they couldnt find my name on their database..

thanks for the help..

I would imagine it always helps to have your name on the post box also.
