Hi Peter,
that certainly helps, thanks a lot.
There's one thing I've noticed though: The location search of the AdWords API relies on more information that is present in the downloadable CSV:
If I enter the names of local city districts, it can correctly find matching zip codes, although those names don't appear in the CSV.
I think we can probably do without, but ideally I'd have that data too.
Cheers,
Jens
