It's also extremely annoying when driving in the states as a Canadian, since our postal codes don't follow the same format. Canadian postal codes are six character alphanumeric strings with alternating letters and numbers, so you can't enter them on the keypad. The trick, which isn't obvious, is that you're supposed to drop the letters from your postal code, leaving three digits, and then append two zeros to the end. For example: K9Z 2P7 -> 92700. In Canada we don't have to deal with this, since pretty much all our pumps have supported EMV chip cards for years.
