You're right, thank you for correcting that, I will try to be more careful in future edits. I flagged this for review because I'm still new at this. For what it's worth, Google Maps was not what led me to believe the postal code was wrong, it was that I was under the apparently mistaken assumption that everything on the same side of a block is going to have the same postal code, especially if it's the same building. Now I know better.
