Tesla has a referral program where Tesla owners can give friends exclusive benefits on Model S, Model 3, Model X, Model Y and solar panels with their personal referral code. The referrer will get a price from Tesla and the referring friend will receive free credits for supercharging on his/her new Tesla.
This is a list of owners that has referred friends and followers to buy a new Tesla or solar panel. The numbers are updated serveral times a day, but are not complete do to the impossible task of gathering all the referral codes in the world.
Tesla does not allow listing referral codes so codes are listed by first name.
