How do I know if my McDVoice survey code is valid?

[N.047305140]

To check if your McDVoice survey code is valid, visit the official survey website at www.mcdvoice.com. Enter the 26-digit survey code printed on your McDonald's receipt in the designated field. Ensure you input the code accurately, as any errors will prevent validation. Typically, survey codes are valid for seven days after your purchase. If your code is expired or incorrectly entered, you’ll receive an error message. Always check your receipt for eligibility details and complete the survey within the time frame specified. A valid code ensures you can share feedback and enjoy rewards for your participation.
