Also, zip codes with leading zeroes have to be converted on output, while no conversion would be necessary if they were preserved in a text representation. I've also seen the equivalent to zip codes in foreign countries including non-numeric digits. Granted, you may not have a present need for foreign zip-type codes, but they do exist. <snip>
