Kroger survey codes, found on your store receipt, typically expire after a specific period, usually within 7 days of your purchase. These codes allow you to participate in Kroger’s customer feedback survey at kroger.com/feedback. If you miss the expiration window, the code becomes invalid, and you will not be eligible to complete the survey or enter the sweepstakes for a chance to win rewards. It’s important to check your receipt for the exact expiration details, as they may vary by location. Complete your survey promptly to ensure your feedback is counted.
