No addresses being found with Google geocoding service

Question

Any address I send to the Google geocoding service is returning ZERO_RESULTS. I am encoding a few hundred addresses, and I haven't hit my limit (would get a different error). Also, the delay between each request is 2 seconds (or more when I stop execution with the debugger). No matter what address I try, I get ZERO_RESULTS. In the past (as soon as a week ago) this has worked fine. Any ideas?

For example, here is a URI that returns ZERO_RESULTS...

http://maps.googleapis.com/maps/api/geocode/json?address=801+BALTIMORE+STREET%2c+Hanover%2c+PA%2c+17331&sensor=false

Answer 1

I tried that URL and I discovered there is a 800 and 802 but no 801 baltimore street in hanover PA. Google Maps knows that address and shows a mall or something.

Answer 2

The result on Google Maps is not for an "address", it is for a "place".

There are three entries in the Places database for "Giant, 801 Baltimore Street, Hanover, PA", but no results from the geocoder for "801 Baltimore Street, Hanover, PA, 17331".
