What if I'm using a courier and don't know when my booking will arrive?

Since you are using a courier/taxi as long as they will take less than 10 minutes to unload they can unload without a vehicle pass. 

If they are going to take more than 10 minutes, or require the use of a forklift, then they will need to make a booking and complete driver details on the day - once the driver details have been completed you are able to print an incomplete pass on which the VRN can be handwritten in.
