SunPass has been made aware that there is a phishing scam targeting the general public. To our knowledge SunPass has not been compromised and we are diligently monitoring the system. The scam uses text messages requesting prompt payment to avoid fees. The messages also contain a link to a fraudulent website in an attempt to collect information. These messages are not sent by SunPass.
Sincerely,
SunPass Customer Service Center
