Every BMW X3 (2018–2024) carries a 17-character VIN that begins with the 5UX WMI. The X3 is a gas SUV; this page shows what each character of a BMW X3 VIN means and gives 4 checksum-valid sample VINs you can drop straight into test fixtures. Synthetic — not real: no scraping, no real-owner data. The generator below is pre-filtered to the X3.
Each sample below is built from the real 5UX WMI and the X3's descriptor, so it decodes to a BMW X3 of the right model year:

Worked on the sample 5UXTR9C53J0084104 — a 2018 BMW X3:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 5UX | Marks the VIN as BMW, built in United States |
| 4–8 | VDS | TR9C5 | Descriptor for the X3 — SUV body, gas powertrain |
| 9 | Check digit | 3 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | J | Code J = 2018 |
| 11 | Plant | 0 | Assembly-plant code |
| 12–17 | Serial | 084104 | Sequential production number |
Positions 1–3 of every BMW X3 VIN read 5UX — the World Manufacturer Identifier that marks the vehicle as BMW, assembled in United States (North America). After the WMI, positions 4–8 (TR9C5 in our seed) describe the X3 itself; see the full 17-digit format.
Position 10 encodes the model year. For the X3, 2018 is code J and 2024 is code R. See the 2024 year code or the check-digit math.

A BMW X3 VIN is 17 characters starting with the 5UX WMI, for example 5UXTR9C53J0084104. Positions 4–8 describe the X3, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 5UX is the BMW WMI, positions 4–8 are the X3 descriptor, position 9 verifies the VIN via a mod-11 checksum, position 10 gives the year, position 11 the plant, and 12–17 the serial. Paste any VIN into the decoder to do it automatically.
The X3 in our seed uses the 5UX WMI (United States). Any VIN beginning with 5UX decodes to BMW.
No. They are synthetically generated but checksum-valid, use the real BMW 5UX WMI, and carry the X3's descriptor and a valid year code — so a decoder returns a BMW X3. No real vehicle's VIN is used.
