Sorry, we're not using web service address validation, yet. We have Per/ZIP4 here, which provides indicators; "Business/residential indicator" and "Residential delivery indicator". I have been moderately satisfied with this solution, and it's not really all that expensive. The product is well maintained, with regular database updates.
The only problem with this solution is that it is based on the USPS address database, which does NOT necessarily validate all "physical addresses". There are some (small town) locations where, perhaps, all the shops on main street get mail to P.O. Box addresses. The USPS database will not even know the address exists and will flag the address as invalid.
Other carriers, like UPS or FedEx, use their own augmented database of physical address locations. I know they offer subscription access to their api's and database, but I've never gone further than research.

Subject: RDI Services for Residential vs Business addresses... suggestions?
I'm working on a project that requires the use of an RDI (residential delivery indicator) web service on the IBMi.
I see the USPS doesn't provide the APIs.. instead you need to use a qualified vendor.
We don't want to use it for saving money on deliveries, but instead to go through a mailing list database and distinguish between residential and business address (this project we only want the business addresses, not the home offices).
Preferably XML or JSON (or the option of both) for sending and receiving would be the best option. We just want to send an address to the service and receive if it's residential or business address.
