Random zip code or random five digit number? The reason I ask is that not every five digit number is a zip code. So it is possible that the system can check against known zip codes, but won't cross-check the actual zip code registered to that card. Most of my friends default to 90210 when prompted for a zip in the US as the only zip code they know!
