To register for the survey, participants must be at least eighteen years old. There is a maximum of one survey coupon per transaction, and each coupon may only be used once. Both the voucher and the verification code need to be shown in order to redeem any incentives. Please be aware that there is no cash exchange for incentives.

We value the time and effort you put into completing the White Castle Customer Satisfaction Survey, and in return, we will provide you discount vouchers. White Castle will give you a coupon redeemable for two complimentary cheeseburgers or hamburgers if you use these codes to buy anything from their store.
