My two are sites that insist on picking "State" from a list of US States for a UK address and the forms that reuire you to rekey every field if a mandatory field is missed or an invalid value entered.

How 'bout the English-language forms that list all the countries in the world in an alphabetical dropdown? "Are we there yet?" "Hold on, dear, we just passed Uganda."

many address validation routines insist that my legal address is invalid because it's not in their database

Ever lived on an alphabet street? Apparently some address processors auto-expand N,S,E,W to North, South, East, West ... even if the NSEW isn't followed by anything. I used to live on E Street. Unfortunately my town also contains an East Street.

We won't talk about the ones who are certain they know better than your home town's mapmakers which end of the street is Smith Street, unmarked, and which end is East Smith or West Smith, marked. One of these days I'm going to bike down to West My Street, My House Number, apartment number My Number, and see if I find the person whose mail keeps showing up in my box addressed simply to My Street And Number. One time UPS even tried to deliver.
