Every Buick Enclave (2018–2024) carries a 17-character VIN that begins with the 5GA WMI. The Enclave is a gas SUV; this page shows what each character of a Buick Enclave 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 Enclave.
Each sample below is built from the real 5GA WMI and the Enclave's descriptor, so it decodes to a Buick Enclave of the right model year:

Worked on the sample 5GAEVAKWXJJ246372 — a 2018 Buick Enclave:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 5GA | Marks the VIN as Buick, built in United States |
| 4–8 | VDS | EVAKW | Descriptor for the Enclave — SUV body, gas powertrain |
| 9 | Check digit | X | Mod-11 checksum over the other 16 characters |
| 10 | Model year | J | Code J = 2018 |
| 11 | Plant | J | Assembly-plant code |
| 12–17 | Serial | 246372 | Sequential production number |
Positions 1–3 of every Buick Enclave VIN read 5GA — the World Manufacturer Identifier that marks the vehicle as Buick, assembled in United States (North America). After the WMI, positions 4–8 (EVAKW in our seed) describe the Enclave itself; see the full 17-digit format.
Position 10 encodes the model year. For the Enclave, 2018 is code J and 2024 is code R. See the 2024 year code or the check-digit math.

A Buick Enclave VIN is 17 characters starting with the 5GA WMI, for example 5GAEVAKWXJJ246372. Positions 4–8 describe the Enclave, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 5GA is the Buick WMI, positions 4–8 are the Enclave 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 Enclave in our seed uses the 5GA WMI (United States). Any VIN beginning with 5GA decodes to Buick.
No. They are synthetically generated but checksum-valid, use the real Buick 5GA WMI, and carry the Enclave's descriptor and a valid year code — so a decoder returns a Buick Enclave. No real vehicle's VIN is used.
