I think your code would be much easier to read and maintain if you used separate checks for each zip code type. I do not know about Australian zip codes, but cflib has functions for Canada, UK and US zip codes

yeah, what you need is to call separate functions for each type you need.  then have one master function to validate all.  As _agx_ says.

e.g.



<cffunction name="checkZip" returntype="boolean" output="no">
	<cfargument name="zip" required="yes" type="string">
	
	<cfif 	IsZipUK(arguments.zip) OR 
			IsZipAU(arguments.zip) OR 
			IsZipUS(arguments.zip) OR 
			IsZipCA(arguments.zip)>
		<cfreturn true>
	<cfelse>
	<!--- invalid format --->
		<cfreturn false>
	</cfif>
</cffunction>
