From what I've seen every solution that provides this actually gets their
data from USPS. IF that makes sense. That's of course only what I've
read while researching this.
And we're not really looking for address verification. Just a way to
determine if it's residential or a business address. I suppose the
validation would be just a byproduct of this process as well. :) We want
to omit residential addresses (which in this case would be "home
I did fine a few APIs from USPS to validation that are free, but they won't
do RDI. That is what you have to pay for one way or another.
USPS lists vendors that offer the RDI services. But it seems these guys
don't like to post tech info on their site.. they always want you to call
and set up a demo. One way to get your info I guess. haha..

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
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
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.
