Looking for a way to VERIFY the Delivery Address is correct, in real time while entering the address into a VFP form.

The Delivery Address maybe retrieved using;

- The address itself (to verify that is indeed a VALID US address)
- via the person's phone number (is also available),
- via his/her first/last names.

If you have implemented such features in your application (or have heard about it), I would appreciate your feedback/inputs.

Thanks
