Hotlisting is the temporary deactivation of a SunCard. The Florida Department of Transportation monitors SunCard usage. Hotlisting may be the result of not tapping on and off, an outstanding negative balance due to max fare, using the SunCard for trips that are not part of the purchased pass or running out of funds. If this happens, the SunCard is not valid for travel. A call to Customer Service at 855-RAIL-411(724-5411) prior to boarding is necessary and can easily resolve any concern.
