Contact Plus Add-on

The Contact Plus add-on requires explicit consent from your end users, and once obtained, allows TeleSign to directly access a subscriber’s name and address on file with the carrier. The information included by this add-on is details about the subscriber who owns the phone associated with the phone number:

  • First Name
  • Last Name
  • Street Address
  • City
  • State (or Province)
  • Country
  • ZIP Code
  • Email address

Consent for Contact Plus

In order to use the Contact Plus add-on, you must obtain explicit consent from your end users. In your application, create a message asking if it is okay to verify the end user’s name, address, and mobile number with a mobile service provider. An example of the message might be ‘You agree that we may verify your number in order to verify your identity, and you consent to having this information reviewed, disclosed, and compared for this purpose.’ Another example might be to provide them with a written notice of your Terms and Conditions (including this request for consent) that reads ‘I have read and agree with the Terms and Conditions, including the disclosure of my personal information about me by third parties for the purposes of identity verification.’
