I was recently faced with the challenge of creating an audience consisting of customers who live in particular zip codes. The list of zip codes that I had only include the first 3 digits however.
The closest you can get to this in the current system is with a "contains" rule. See attached screen-shot below. However this rule could end up including other zip codes that end in those last three digits.
in this instance I had to list every single possible post code. Would it be possible to create a new "begins with" option in that second drop down.
