CIRCLE WITH A DOT

@denis As a user, that is my preferred way. Plus it really doesn't take that much work to click a dropdown and type e.g. "D" to get to the right country. (I do like dropdowns that put the most obvious country at the top though, so if you're a German shop, by all means put Deutschland first, because the odds are that's correct for the majority of people.)

@denis The problem with putting the ZIP code first is that there are 58 countries and states with the same five number format, Germany obviously being one of those. So putting in five numbers does not tell you where the customer is (you could use a combination with IP, but especially in the EU for example you will often have customers order from a store in another country, or use a credit card that's registered somewhere else, e.g. Croatia, Finland, France, Italy, also use five numbers).
