> postal (aka zip) codes Post codes aren't quite the same thing as Zone Improvement Plan codes. ZIP codes are just the peculiar implementation in the US of the general post code concept. An important difference between ZIP codes and Canadian post codes is that, since there are many more possible post codes than ZIP codes, post codes tend to cover much smaller regions than ZIP codes. In many cases, only a handful of individuals up to a single individual may have a Canadian post code. Thus, publishing Canadian users' post codes can severely harm Canadians' privacy, as you may as well be publishing their exact address.
