Feature request from joh-klein, posted on GitHub Apr 16, 2015
The current region codes for Germany seem not to be widely known (a quick Google search didn't reveal a source for them). And some others seem to be impractical but most importantly will probably hinder exchanging addresses with other systems.
I could provide a PR with the current data for regions from Wikipedia for these 13 countries (US, CA, DE, AT, CH, ES, FR, RO, FI, EE, LV, LT, BR). Right now I lean towards adding another column for backwards compatibility.
