ZIPCode
ZIPCode validates a US ZIP code of the form ##### #####-####, providing equivalent functionality to the <cfinput validate="zipcode"> tag. . It does not verify that the code is valid - merely that the format is correct. The primary components of this preset are a regular expression to validate the postcode, and a custom error message. Note that this preset is unsuitable for use on forms exposed to an international audience as ZIP / postal code formats vary widely. This preset could easily be adapted for other formats.
