Cyrus,

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

There are basically three options for verifying an address:

1. POST the address to the USPS web site (or some other) and parse the results. This is not a supported use of the USPS web site, but they have no current plans to prevent this type of automation. The main problem is that this site is very bad at correcting slight errors in an address.

2. There are 3rd party controls which can CASS certify (apply plus4, delivery-point and verify) the address. These require a subscription to regular updates to the fairly large postal database. Usually several thousand $ a year.

3. There are some 3rd party CASS services, as in #2, which are subscription based web services. These do not require any updates to local postal data, but charge on a per/transaction basis. Depending on volume, this could get expensive.


As for looking up the address from a name or phone, the only way I know to do this (without direct access to phonebook libraries), is to POST the search data to a directory website and parse the results. I would not be surprised if most of these sites now have methods to prevent people from submitting more than x number of transacitons during a specified time period). A good resource for phone directories is http:\\www.theultimates.com


If you need more info on one of the other services, let me know and I'll dig up the links.
