If you’re departing from Gatwick, you can collect your membership card from the Skybreak desk located in Zone K near the entrance to the train station within Gatwick south terminal. When starting your subscription, for Step 3/6 (Card Type), make sure to select “I already have a new Bluecity card. I will receive my association code by text message when my subscription is validated” to be able to use the membership card which you collect from the Skybreak desk.
If you’re not at Gatwick, you’ll need to wait to receive your membership card to be able to rent a car. You should receive your membership card within a couple of working days once your subscription has been activated.
