To redeem your McDVoice survey reward, first, complete the feedback survey at www mcdvoice com using details from your recent McDonald’s receipt. Upon successful submission, you'll receive a validation code. Write this code on your receipt as proof of participation. Present the receipt with the validation code during your next visit to a participating McDonald’s location. Depending on the offer printed on your receipt, you can claim rewards like a free menu item or discounts. Ensure the receipt is valid within the timeframe specified, typically 7 days, to avoid missing out on your reward from the McDVoice survey.
