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 SCA666D5 and position 10 reads J. 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 | SCA | ROLLS ROYCE MOTOR CARS · World manufacturer identifier |
| 4–8 | 666D5 | Model, body style, engine and restraint system |
| 9 | × | Check digit — computed per vehicle, not part of the build |
| 10 | J | Model year — 2018 |
| 11 | × | Assembly plant |
| 12–17 | ×××××× | Production sequence number, unique to each vehicle |

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.
Prices are asking prices from 25 live dealer listings decoded to this build , last updated September 6, 2026 . They are what sellers ask, not what buyers paid.
Vehicle counts come from the 256 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
