Hi Rainer,
I installed the Google Maps Delivery Link Add-on and tried to verify a customer's order. This customer did not select the state in the US and left the default AL - Alabama. Google Maps failed not showing anything other than possible location in the URL of the browser.
Google Maps will not validate the address unless one utilizes Google's address validation:
https://developers.google.com/maps/docu ... te-address - There maybe a cost involved with this validation.
Using the USPS Address Validation API doesn't charge anything for the lookup.

I thought it would be better to be proactive and implement it on the account creation and guest checkout to ensure accurate information is entered by the customer. Maybe the next update for 1.0.8.21 ?
Thanks,
Craig
