Customers can take the Taco Bell customer satisfaction survey at TelltheBell.com. To take the survey, customers enter the 16-digit survey code located at the top of their meal receipts. Customers without survey codes or receipts can enter information about their dining dates, times and locations to take the survey.
As of 2015, survey takers are eligible to win a $500 cash prize. The sweepstakes is only available to U.S. residents age 18 and older. Taco Bell awards one cash prize every entry period, and there are 24 entry periods in a year. Individuals can also enter the sweepstakes by mailing a postcard entry form. No purchase is necessary.
