WWP can utilize telephone verification in circumstances where individual respondents must be identified as unique human respondents. This technique is primarily used in order to identify simulators or bots that may impersonate several unique respondents to one survey.

Telephone verification is used to verify the authenticity of a new panel member but can also be used upon re-direct to a survey (paid service). Users are required to provide a phone number so that our application can contact them and request that they input a code provided by our system via email or SMS.

Generally, this is used during registration or at the start of a survey. The user is contacted via telephone and is required to enter a unique code in order to complete the registration process of beginning a survey. We then verify that code and allow the user to continue based on the results of the verification process.
