If your Kroger survey code is not working on www.kroger.com/feedback survey, there could be several reasons. First, check if the code has expired, as Kroger receipts have a limited validity period for survey participation. Ensure you’ve entered the code correctly, as even a small mistake can cause errors. Also, verify that your receipt is from a participating store. If the issue persists, try using a different browser or clearing your cache. Some surveys have limits per household, so you may have exceeded the allowed entries. For further assistance, contact Kroger customer support or check their official survey guidelines.
