Dunkin’ Donuts customer satisfaction surveys are available at TellDunkin.com and can be filled out and submitted for free but require a receipt from a Dunkin' Donuts purchase. A consumer enters an 18-digit survey code located in the middle of the receipt to access the survey.
If the receipt does not have a survey code, a six-digit store location listed on the top of the receipt and the date and hour of the visit may be entered instead. The survey asks consumers to rate their satisfaction on a scale that ranges from highly satisfied to highly unsatisfied. It also asks for a satisfaction rating for the taste of the food, the courtesy of the staff, the ease of placing an order, the speed in which the order was filled and product availability.
Additionally, Dunkin’ Donuts offers a survey redemption as of 2015, in which consumers can present a receipt and survey validation code in order to receive one free donut with the purchase of a medium or large size beverage.
