Hi Jeff,

I do care about the zip code because I use it to verify the result
before updating my database with the coordinates.
I am geocoding a list of schools in the US, but in some cases, the
returned result was in Canada, so I discarded it.
It is because of this zip code check that I became aware of the issue.

I posted it to the issue tracker:
