>> 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.


Thank you so much Dan. Seems like # 3 is what would prbably work for me.
I would appreciate the links if you still have them.

Also, if you have any sample code for Posting/Parsing, it would come real handy.

Thanks Again.
