Syntax

StateValidForZip( <cZip>, <cState> )

 

Purpose

Given a specific zip code and state abbreviation, this function will return true if the given zip and state are a valid combination to use in an address. When used in a custom selection, this function can identify the constituents in your database which have an invalid zip and state combination in their mailing address. Once in a selection result, these invalid addresses may then be viewed and corrected as a group. A typical custom selection expression using this function would be: StateValidForZip( .Zip., .State. )

 

Parameters

<cZip> Is the zip code to check. Must be a character (alpha-numeric) value since zip codes may contain a dash. In a custom selection, this is typically the .Zip. field, though it may be any field containing a zip code.

 

<cCounty> Is a character value giving the state abbreviation (in uppercase) to check. In a custom selection this is typically the .State. field, though it may be any field containing a state abbreviation.

 

Returns

A true/false value.

 

Usage

This function can be used with custom selections. For example, a custom selection could be written to find all the constituents which have an invalid zip and state combination in their main address.
