The Tell Dunkin' Donut survey is a customer satisfaction survey for the Dunkin' Donuts company. It is an online survey customers complete through Dunkin' Donuts' survey site, TellDunkin.com. The website offers the survey in both English and Spanish.
At the start of the survey, a customer enters a survey code found near the bottom of a Dunkin' Donuts receipt. If the receipt does not have a survey code, a customer can choose to enter purchase details instead. A customer enters the store number for the purchase and the date and hour of the purchase. The top of the Dunkin' Donuts receipt contains all these details.
