Tesla referral codes
A Tesla referral code.
Drawn fairly,
and measured.
Tesla owners contribute their referral code here. You get one at random from the pool — not whoever paid for the position, not whoever arrived first. The draw is uniform, and we measured it rather than claiming it.
- 01
Take a code
One per day, no account needed. Save it if you want to keep it — but a saved code is a string, not a reservation.
- 02
Open it before you order
The referral only lasts about a day once opened, so click it just before you place the order — not weeks ahead.
- 03
Check it took
The car's design page should say Referral Applied. If it does not, open the link again. You do not need a Tesla account to see it.
The draw, measured
400,000 draws across 10,182 codes. Every bar is one code's share. Flat is the point.
The obvious way to pick a random row is biased, and badly: the first approach we tried gave the luckiest code 12.7× the average and never served 2.4% of codes at all. We measured it, threw it away, and built the one above instead. Share a code here and it competes on the same terms as every other code in the pool.
The site owner's code is in the same pool as everyone else's. When the promo is on, it gets a small fixed share of requests — never more than 5% — before the fair draw; when it is off, it competes like any other code.Why, and what that means →
