To take the TellCulvers survey, customers need a recent Culver’s receipt that includes a survey invitation. Visit tellculvers.com/survey and enter the required details from the receipt, such as the survey code or transaction information. Once entered, participants answer a series of straightforward questions about their visit. The survey usually takes about five to ten minutes to complete. After submitting feedback, a validation code is provided, which can be written on the receipt and used to claim the reward during a future visit to a participating Culver’s location.
