Your fuel card is linked to your car and can't be used for other cars. You can pay at the station with your fuel card, using your 4 digit pin. Please note that not all fuel stations allow pay-at-the-pump and you may need to go inside.
Have you forgotten your PIN code? Please contact LeasePlan at 1-855-588-3677 or your fleet administrator. Did you enter the wrong PIN three times? Then you are only blocked for 48 hours. You can use the fuel card again after 48 hours.
