Giving someone a phone number or email address over the phone

[Llamas]

It's been proven that the most mistakes in writing down numbers are made in The Netherlands and Germany. Reason for this is because of the "sixteen" case above. We have that for all numbers.

Twentysix = six-and-twenty in Dutch/German.

I'd imagine that Slovenia ranks with the Netherlands and Germany, then, cause they say their numbers that way, as well. I'm used to it cause I speak German, but it can still be really confusing when I hear the "wrong number" first.
