Address Validator AddressHero

This app really helped us prevent one of our main customer facing pain points: failed deliveries due to missing house numbers. In combination with the address verification based on "DHL Leitcodierung" (specific German requirement) our delivery data became much more accurate. I also was in touch with David who was willing to an edge case that maybe only we as a shop have but directly transferrred our request to the app's dev team. I can highly recommend the app.
