No, I'd look at IP addresses before validating zipcodes, true ;) What I'm thinking is, if someone wants to deceive a service provider about her billing address, that's a social problem. Social problems are insanely hard to fix with technology, if at all.
So what is reasonable to request from the service provider here? Checking billing address and IP is reasonable, but beyond that? Maybe bank account? But in Europe a German can have a bank account in France, it is not even a big deal. Maybe taxation should follow bank accounts? I have an account in Luxembourg, so I'm set ;)
