To take the McDVoice survey, customers need a recent McDonald’s receipt with a survey code printed on it. Visit www.mcdvoice.com survey and enter the required information from the receipt, such as the survey code, store number, and date of visit. After that, answer a series of questions about your dining experience. The process is simple and typically takes five to seven minutes. Once completed, you’ll receive a validation code that can be written on your receipt and redeemed on your next visit.
