You can earn extra rewards by inviting your friends to use Carrot Rewards. Just go to the “Friends” tab in your Carrot app, and you will be able to find your user code by selecting "connect to a friend". Your user code is visible in the top right corner. You can also select "invite a friend to Carrot" and your user code will be included with an invitation that you can send via text, email or social media. When your friend signs up to Carrot and enters your user code during the signup process, you will earn extra rewards (and they will too!).
Please note that a new user can only be referred by one person and that in order for you to earn rewards for referring them, they must enter your personal bonus code within the first 10 days of signing up to Carrot. They must also complete the registration process fully and confirm their email address.
