Rolls-Royce VINs: why the check digit is deliberately not claimed

Rolls-Royce sits under BMW in the decoder, and one of the few decisions made about it was to do less rather than more.

Is a Rolls-Royce GCC spec?
The honest answer, before anything else on this page.

GCC specification is decided per vehicle, not per model. Two cars of the same model and the same year, built in the same factory in the same week, can go to different markets. So no page can tell you whether yours is a Gulf car, and this one does not try. What it can do is show you exactly what your own VIN encodes and where that stops.

How Rolls-Royce builds a VIN outside America
The scheme, and why a general decoder struggles with it.

Rolls-Royce VINs begin SCA and are built at Goodwood. The decoder reads them with BMW's structure but keeps a separate plant table, because the letter C means Crewe on a Rolls-Royce and Dingolfing on a BMW, and U means Goodwood only for Rolls-Royce.

The check digit is deliberately not claimed here. BMW's conforming digit was established on six real European BMW and MINI VINs, and no Rolls-Royce has ever been checked. A false positive there would report a genuine car as mistyped, on a car whose owner is least likely to accept being told so, so the rule is narrowed to exclude the SCA WMI until a real sample exists.

Position by position
What each character carries on this maker's cars.
4 to 7
The BMW type code, or Typschluessel
Four characters that resolve model, chassis, body and engine in one field. This is exactly the field the American reference cannot read, because BMW never filed these cars with the American regulator. On a US-market BMW positions 4 to 7 are not the plain type code, so the lookup only runs when the rest-of-world marker is present.
9
A genuine check digit
Europe does not mandate one, but BMW computes a conforming mod-11 digit anyway. Every sampled European BMW and MINI validates, which turns this into a free typo detector on exactly the VINs where there is otherwise least to say.
10
The literal digit 0 on a rest-of-world BMW
Not a year code, and not even a member of the year alphabet. The model year is simply not in the VIN. The decoder returns no year and shows the type code's production window separately, because promoting a window into a year would be fabricating data.
11
Plant
Read from BMW's own filed plant letters. Where a letter means different plants for BMW and for Rolls-Royce, the decoder keeps separate tables rather than one that is right half the time.
World manufacturer identifiers
The first three characters, and the entity behind each. Country is where the vehicle was built, which is not where it was sold.
