Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number.

How to read a Toyota GR Corolla VIN
Here is a real 2026 Toyota GR Corolla VIN from our database, split into its parts:
VIN JTNABAAE3TA024477 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |
| 11 | Plant | The assembly plant that built the car. |
| 12–17 | Serial | Sequential production number of this exact vehicle. |
Toyota GR Corolla VIN prefixes, and when each one was used
Characters 1–3 are the World Manufacturer Identifier. Every Toyota GR Corolla we have on record, from 2023 to 2025, carries the same one — JTN, which makes it a quick way to confirm you are looking at a real GR Corolla:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| JTN | 2023–2025 | Japan | Passenger Car |
Counted from the 25 dated Toyota GR Corolla VINs attached to NHTSA complaints — the largest such set for this model — with every code checked against the NHTSA manufacturer registry, so mistyped entries are dropped; the figures say how many records carry each code, not how many GR Corollas left the line.
Model-year codes for the Toyota GR Corolla
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Toyota GR Corolla has not yet outlived — its 4 years still map one-to-one. All 4 model years of the Toyota GR Corolla, 2023 to 2026, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2026 | T | — |
| 2025 | S | — |
| 2024 | R | — |
| 2023 | P | — |
When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.
Body and engine characters we see on Toyota GR Corolla VINs
Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 20 VINs the Toyota GR Corolla uses 4 different characters in these three slots alone — the ones below, ordered by how much of the Toyota fleet each covers:
| Position | Characters seen on real VINs | Variety |
|---|---|---|
| 4 — body | A (100%) | 1 distinct |
| 5 — series | B (80%) · D (20%) | 2 distinct |
| 8 — engine | E (100%) | 1 distinct |
A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.

Where to find the VIN on a Toyota GR Corolla
A Toyota GR Corolla VIN normally opens with JTN. Four places on the car carry the full number, and all four must agree — on a Toyota GR Corolla, a plate that disagrees is where fraud shows itself first.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tyre pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this Toyota GR Corolla VIN decoder free?
Yes — decoding a Toyota GR Corolla VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the Toyota GR Corolla — 5 recall campaigns and 25 owner complaints — at no charge.
How many characters is a Toyota GR Corolla VIN?
Seventeen, on every Toyota GR Corolla built from 1981 onwards, when the 17-character format became mandatory in the US. The oldest Toyota GR Corolla VIN on file here is a 2023, so everything in our Toyota data already uses the modern layout.
Why do two Toyota GR Corolla model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.
Can a Toyota GR Corolla VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the Toyota GR Corolla left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. What is public are the 25 complaints Toyota GR Corolla owners filed with NHTSA, and those we do show. Run the number through our VIN check to see what is on the record for it.
Do the body and engine characters mean the same thing on every Toyota?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the Toyota GR Corolla can mean a different one on another Toyota, and something else again on another marque. On Toyota GR Corolla VINs the character that dominates position 4 is A — read it against the table above, not against a generic chart.
What if the VIN on the dashboard doesn't match the door jamb?
Treat it as a red flag on any car, and on a Toyota GR Corolla check the prefix first: for the model year in question it should open with JTN, depending on when the car was built — anything outside that set did not come off a Toyota GR Corolla. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
