Below is security feature that can be added to an "open" survey link to ensure that you have a real respondent taking your survey. After we collect a telephone number from the respondent, they will be sent a short confirmation code which must be entered on the next screen before they can continue with the survey. Each confirmation code can only be used one time. We can also limit each telephone number to only one use.

Please enter your SMS capable telephone number. Once you enter your number and click "Continue" below, we will send you an authorization code via SMS which is required to continue with this survey.
