I was looking at a package I got the other day and noticed the order of the address was wrong.
Addresses have very different formats in each country, yet every single website still asks me for my “State/Region”. This field is completely useless here in France, and many other countries. Sometimes it's a text box, and I don't know if I can leave it empty or if I have to input “N/A” or something else that will look stupid once printed on the package. Sometimes it's a drop-down list and I have to hunt down either the “Non-US” option, or maybe it was filled with French regions or French departments once I picked my country.
