Well, this list shows 293 ZIPs that cross state lines [0], this FAQ says there are ~43,000 ZIPs in use [1] so that puts it closer to 99.3%.
But think about it, if you're taking an address to ship something, getting the ZIP right is what matters. If your package has 45201 on it, it doesn't matter if it says Cincinnati, OH or Cincinnati, KY.

- apendleton 13y agoBut if you're collecting a billing address (probably more common, since many places bill but don't ship, e.g., for digital goods, but not that many ship without billing), and are trying to expedite filling out the form by guessing the city and state from the zip, I doubt the payment processing would succeed if you got the city or state wrong. All depends on the situation, I guess.

- chrisbolt 13y agoAVS[1] doesn't even look at the city/state. It only checks the ZIP (5 or 9 digit) and the numbers in the street address. [1] http://en.wikipedia.org/wiki/Address_Verification_System http://en.wikipedia.org/wiki/Address_Verification_System
