Basically what we're getting at here, is let's say someone is filling this thing out and right now you must have your town, your province, your postal code listed. Let's say they put “John Smith, 123 Jones Street, Toronto”, and then they put their postal code and they forgot to put Ontario. Now you can say, that's pretty obvious where this person is and you're able to verify it, rather than say, “Well, it doesn't have Ontario, so we can't go with it.”
Is that basically what we're talking about here?
