Unfortunately, dws's approach isn't always possible.
The system I work on handles significant volumes of addresses, using dedicated (commercial) software to handle the identification and validation of that information. The volumes involved prevent it being practial for humans to process the problem records (and in fact some of those problem records are a direct result of human input).
Even if the volumes were low enough for humans to be able to process exceptions, humans can't get it right all of the time. As shemp describes, even reference data used in such validation systems isn't perfect, and this sets the upper limit to what you can reasonably expect to acheieve.
I'd say that you can never expect to get things 100% right, and it might end up being cheaper and/or easier to accept a certain error rate.
Cheers. If the information in this post is inaccurate, or just plain wrong, don't just downvote - please post explaining what's wrong.
