How this VIN pattern is read
A 17-character VIN carries two kinds of information: what was built, and which one it is. This page is the first kind — the nine highlighted positions.
VIN positions 1 through 8 read 1GNSKBED and position 10 reads M. Those nine characters define this build. Position 9 and positions 11 through 17 describe the check digit, assembly plant and production sequence; they are not part of this pattern.
| Positions | Characters | What they encode |
|---|---|---|
| 1–3 | 1GN | GENERAL MOTORS LLC · World manufacturer identifier |
| 4–8 | SKBED | Model, body style, engine and restraint system |
| 9 | × | Check digit — computed per vehicle, not part of the build |
| 10 | M | Model year — 2021 |
| 11 | × | Assembly plant |
| 12–17 | ×××××× | Production sequence number, unique to each vehicle |

Useful answers, without the guesswork
2021 Chevrolet Suburban: specification questions
What engine code is recorded for 1GNSKBED-M?
The recorded engine model is L84 - DI, ALUM, GEN 5, VAR 2. This is pattern-level data; confirm the installed engine on a vehicle that may have been modified.
Is this an original window sticker?
No. This page summarizes decoded VIN-pattern specifications. An original sticker or build record is needed to verify the optional equipment of a particular car.
Are the known VINs a production total?
No. These are VINs observed in our records. The count does not establish total production or rarity.
Does a missing specification mean the feature is absent?
No. Missing fields mean that a value is not recorded in this decode. Check the individual vehicle and its manufacturer documentation.
Where this data comes from
Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.
Vehicle counts come from the 163 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
