The Ultimate Tesla VIN Decoder

Every Tesla VIN is a 17-character code that reveals the car's DNA. While the DMV uses it for registration, enthusiasts use it to find "Unicorn" builds — like an Austin-built Model Y with the structural 4680 battery pack.

Positions 1–3: World Manufacturer Identifier

This tells you where the car was built.

5YJ — Tesla Inc. USA (Model S / Model 3)
7SA — Tesla Inc. USA (Model X / Model Y)
LRW — Tesla China (Giga Shanghai)
XP7 — Tesla Germany (Giga Berlin)
7G2 — Tesla Semi / Cybertruck (USA)

Position 4: The Model

S = Model S · 3 = Model 3 · X = Model X · Y = Model Y · C = Cybertruck · T = Tesla Semi

Position 7: Battery & Fuel Type

This digit is the most important for knowing whether to charge to 80% or 100%.

E: Lithium-Ion (NMC/NCA) — Standard in Long Range/Performance.
F: Lithium Iron Phosphate (LFP) — Standard in RWD/Standard Range.
H: High Capacity LFP (Found in newer 2025/2026 refreshes).
S: Standard Range (Trucks) · R: Long Range (Trucks).

Position 8: Motor / Drive Unit

D: Single Motor – Standard
E: Dual Motor – Standard (AWD)
F: Dual Motor – Performance
6: Triple Motor (Plaid / Cyberbeast)
J / K / L: "Hairpin" Windings (Newer, high-efficiency motors found in 2024+ models).

Position 10: The Model Year

Tesla follows the industry standard codes: R = 2024 · S = 2025 · T = 2026

Position 11: The Factory

F: Fremont, California · A: Austin, Texas (Giga Texas) · C: Shanghai, China · B: Berlin, Germany

Why This Matters for Buyers

If you are looking at a used Model Y and the 11th digit is "A" (Austin) and the 7th digit is "E", you have a car with the structural battery pack — potentially lighter and stiffer than the Fremont builds. If the 7th digit is "F", you have the LFP battery, meaning you can charge to 100% every single day.
