W1W4EBHY3RP794221 → 11th character = P

Here the assembly-plant code is P.

The 11th character is the assembly-plant code — it identifies the specific factory where the vehicle was built. The mapping from character to plant is manufacturer-defined, so the same letter can mean different plants for different makes.

Two otherwise-identical vehicles from different factories differ at position 11, which is useful for tracing recalls and production batches to a plant.
