How to read a BMW 635CSi VIN
Here is a real 1989 BMW 635CSi VIN from our database, split into its parts:

| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |

Where BMW 635CSi VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 3 BMW 635CSi VINs we have on file, these are the codes that actually show up — and the plants behind them:
| WMI | Built in | Vehicle type | VINs on file | Share |
|---|---|---|---|---|

Country and vehicle type come from the NHTSA manufacturer registry. Share is measured across VINs decoded on ForCar, not production volume.

| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
