Thanks EdshOt for your answer ( and to the OP for the original question). I don't just half as stupid as I first did a second ago there after having to turn to google to find the answer to that to enable me to complete my Tesla trade in value page!
Ironically Tesla don't seem to use it - they had ours down wrong, about 10 years older and were not in the slightest bit interested in fixing it as they said they used the info from the VIN.
