How to read a Jaguar XJ VIN
Here is a real 2019 Jaguar XJ VIN from our database, split into its parts:
VIN SAJWA2GE4KMW22330 — 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. |
Jaguar XJ VIN prefixes, and when each one was used
Every Jaguar XJ we have on record, from 2003 to 2019, opens with the same three characters, SAJ:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| SAJ | 2003–2019 | United Kingdom | Passenger Car |
Position 11 names the plant. On the Jaguar XJ it is not one number either — assembly moved between 4 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|
| S | 2004–2008 | 26 | |
| L | 2003–2011 | 11 | |
| T | 2004–2006 | 6 | |
| M | 2011–2011 | 6 |
Counted from 51 dated Jaguar XJ VINs attached to NHTSA complaints, each code checked against the NHTSA manufacturer registry.

Where to find the VIN on a Jaguar XJ
A Jaguar XJ VIN normally opens with SAJ; the full number sits in four places, and all four must match.
| 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 tire 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 Jaguar XJ VIN decoder free?

What year is my XJ by its VIN?
Read position 10: a 2019 XJ carries K, a 2018 XJ carries J, a 2017 XJ carries H.
Where was my XJ built?
Position 11 names the plant. Across 51 dated Jaguar XJ VINs it reads S 51%, L 22%, T 12%, M 12%.
What does position 4 mean on a Jaguar XJ VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 37 Jaguar XJ VINs here, W is the most common character in position 4, on 84% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a Jaguar XJ check the prefix first: most genuine ones open with SAJ. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
