2. As you have already found out yourself, the key does not seem to be region locked. To expand on this, a Guild Wars 2 account is not bound to any region. As an inhabitant of the EU, I can play on both EU or NA servers without changing anything in my account. Therefore, there is no region, as such, for the key's origin to be checked against.
