    Hello Scott,

    I am not sure if I have understood your requirement. DO you want to validate zip code or you want user to only select from a set of zip codes?

    I would suggest you to please take a look at our "Zip Code Auto-Suggest" widget and see if it fits into your requirement. 

    You can also add condition to check the zip code entered by user and see if it is from predefined list. 

    Hope this helps.

    Do get back to us if you have any questions.

    Thank you!

    Yes so I want to put in valid zip codes in the backend. This way people don’t share the contest with friends outside the area just to earn more points because the people outside the area would be a bad lead as they would never visit the restaurant . thanks.. Looks like you have a lot of solutions

    Ps.. can you add your own css to style these?
