The sign says quality. The VIN says what it is.
GMC VIN decoder
Paste a GMC VIN and see the model year, model, body, engine and the plant it was built in, from the record GMC files with NHTSA. Free, no email, and the VIN goes only to NHTSA’s decoder, never to WhichTrim.
17 characters. The letters I, O and Q never appear in a VIN. Find it on the driver's-side dashboard, the door jamb, your insurance card or the title.
GMC’s manufacturer codes (WMI)

What each character means on a GMC
Source: 49 CFR 565Every GMC VIN since the 1981 model year follows the federal format. Positions 4 to 8 are GMC’s own code for the model, body, engine and restraints; the decoder reads them from GMC’s filing, so they need no table here.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | World manufacturer identifier | Who built it and where. 1, 4 and 5 are the United States, 2 Canada, 3 Mexico, J Japan, K South Korea, W Germany, S the United Kingdom. |
| 4–8 | Vehicle descriptor | Model, body style, restraint system, engine — the section that makes a VIN say which car this is rather than which unit. |
| 9 | Check digit | A checksum of the other sixteen characters. A VIN that fails it has been mistyped or invented. |
| 10 | Model year | A letter or digit, not the year itself: N is 2022, P 2023, R 2024, S 2025, T 2026. I, O, Q, U and Z are never used. |
| 11 | Assembly plant | The manufacturer's code for the factory that built this vehicle. |
| 12–17 | Serial number | The unit's own sequence number on that line. |
| Model year | Code (position 10) |
|---|---|
| 2030 | Y |

Source: where to go from hereCommon questions
Source: NHTSA vPIC, 49 CFR Part 565Is the GMC VIN decoder free?
Yes, with no email and no account. The decode comes from NHTSA's vPIC database, the record GMC files with the federal government for every vehicle it sells in the US.
Where is the VIN on a GMC?
At the base of the windshield on the driver's side, readable from outside; on the certification label in the driver's door jamb; and on the title, registration and insurance card.
Does a decode show accidents or title brands?
No. A decode says what GMC built. What happened afterwards (title brands, odometer readings, total losses) is in NMVTIS, sold by providers the Department of Justice approves.
Can I check GMC recalls by VIN?
The decode opens the model year's page here, which lists every recall campaign on file. Whether this exact vehicle is still unrepaired is answered by NHTSA's lookup at nhtsa.gov/recalls, which reads GMC's own list.
Is my VIN stored?
No. The decode runs in your browser against NHTSA's public database. WhichTrim never receives it.
