The Checkout Checklist That Catches a Dying Referral Code
By David · Published
A frequent mid-checkout worry: the code seems to have vanished after switching from a phone to a laptop to finish the order. Usually it hasn't — but it easily could have. Here's the six-point checklist to run before you pay, built from the exact places a code can quietly fail.
Why a checklist instead of a walkthrough
I've already written the full step-by-step order of a Tesla with a referral code applied. This is different: it's the list of exact checkpoints where the code can fail silently, in the order you'd hit them at checkout, so you catch it before you pay instead of after.
The six checkpoints
| Checkpoint | What to look for |
|---|---|
| 1. Before you configure | Open the referral link first — not partway through. This one step prevents most of the rest. |
| 2. Switching devices mid-session | The near-miss to avoid: moving from phone to laptop can start a fresh session. Re-open the referral link on the new device before you continue. |
| 3. Saving and returning later | If you save your configuration and come back the next day, check the code is still attached — a long gap can time out the session. |
| 4. The payment/order step | Look for the "Referral Code" field. If it isn't pre-filled, paste it there yourself. |
| 5. The order summary, before you pay | Confirm the benefit line actually appears — 3 months of free FSD (North America) or free Supercharging (Europe) — before you submit. This is the one screen that matters most. |
| 6. Your model and trim | Model S, Model X and Dual Motor AWD Cybertruck don't carry the benefit at all in North America — no checkout step fixes that. |
The code to have open across every checkpoint

Open Tesla with the code applied →Copy link puts the whole referral URL on your clipboard, because Tesla has no field to paste a bare code into — opening the link is what applies the benefit. Always confirm it shows before you order.
Why this needs a checklist at all
Worth naming the underlying problem, because it explains why the list is six items long instead of one. Every other element of a Tesla order confirms itself: pick a colour and you see the colour; choose a delivery location and it is named back to you; enter payment details and the total appears. The referral is the only part of the transaction with no confirmation step of its own. Nothing tells you it attached, and — the part that catches people — nothing tells you when it detaches.
That is what "fails silently" means here, and it is why the failure modes above are all boring session mechanics rather than anything to do with codes or eligibility. A dropped session leaves no error, no warning, and no visible difference until the one screen where the benefit either appears or doesn't.
The near-miss to avoid
In the near-miss that prompted this checklist, switching devices left the referral field on the laptop's order page blank. Caught at checkpoint 4, the code can be re-pasted and confirmed at checkpoint 5 before paying. Going straight from checkpoint 3 to submitting the order would have meant paying full price for a car with no FSD trial attached — and, per Tesla's own guidance, no guaranteed way to add it back afterward.
If you only remember one checkpoint
Checkpoint 5. Whatever happened earlier in your session, the order summary before you pay is the last chance to see the benefit in writing. If it's not there, stop and fix it before you submit — not after.
Checkpoints 1 to 4 are ways of making that final check more likely to pass; checkpoint 5 is the check. If you know you won't run a six-point list — most people won't, and that's fine — run the one, and accept that you may have to restart a configuration if it comes back empty. Restarting costs fifteen minutes; discovering it after payment costs the benefit.
One instinct that doesn't help: screenshotting the referral link or the code before you start. That records what you intended, not what the session did. The only evidence worth keeping is a screenshot of the order summary showing the benefit — which is also the first moment there is anything real to photograph.
