eCommerce (Online-shops, contact forms and logistics)
If customers can order via the Internet or if they can change data the address should be validated.
The shipment of a product to an incorrect address does not only delay the delivery, but service promises are not kept, either.
Besides the angry customer you might also lose money, because of reshipment and relabeling.
AddressDoctor corrects addresses already during the capturing process and checks validity, orthography and formatting beforehand.
