Mine seems to buck the norm. My top right box has 6 line items: Invoice Number, Invoice Date, Reference Number, Customer Number, Scheduled Delivery Date, and Odometer. The Reference Number is my RN. In the boxes just below the Sold To/Delivery Address it lists my VIN. But nowhere can I see my registration number. I believe the final invoice was prepared prior to them allocating the registration to my car, but that is purely speculation. I'm not worried, only mentioned it if someone else doesn't find their registration on their final invoice they won't panic.
