On the other hand, whatever algorithm they're using for the handwriting recognition on checks is pretty amazing. I've deposited 100's of checks and I've only had to type an amount once.
The USPS also has the additional challenge of matching what you think is your address with what is actually your address. Very, very few people know their address.
If that's not bad enough, if you've ever had something arrive successfully, you expect the address that was used to work forever.
What parts of their addresses do people typically get wrong? Where can one go to find one's actual address?

I've been so impressed before by things like wrong addresses -- hell, one time I saw a letter with no address only my name and zip code. And it's not like I lived in a place where my mail carrier knew me. They've built a hell of a technology there.
