If you are not receiving the text message with the verification code for your reward, please make sure the phone number on your account is correct.
If the phone number is correct, then your carrier may be blocking these text messages. You may contact them about getting them unblocked.
Another option is to use a close friend or family member's phone number to receive the text message or use a VoIP number, such as signing up with Google Voice (if you have a Gmail account, this is a relatively quick process).
If you are unable to update or verify your phone number on your own, you will receive a prompt to enter your new number. Your request will then be reviewed and updated by our support team, and you will be notified once the change has been made.
