I'm looking at our Two Together railcard application (but this may apply to all railcards) and I notice the postcode field isn't compatible with US zip codes (having two fields of 4 digits). Also no specific field to indicate a state and/or country.
Do I do the best I can with what I have? For example, I could put state / USA in the town field and all 5 digits of the zip in the 2 fields of 4 for postcode.
Of course, I'll presenting the application at a station so does it matter? They won't be mailing it to me.
Thanks.
