403 — Leather interior trim: Shale/Cocoa, Mini Perforated. This code identifies the factory upholstery material, color combination, or interior trim specification. Browse RPO codes →
The VIN report includes 403, described as “Leather interior trim: Shale/Cocoa, Mini Perforated. This code identifies the factory upholstery material, color combination, or interior trim specification” I would like to archive the correct information with the vehicle. Is there another factory document that normally confirms this code?

That code should be read as a factory configuration identifier, not necessarily a guarantee of a separate dashboard control. Some equipment operates automatically or is bundled with another system.

The wording may be abbreviated because these were originally production codes rather than consumer descriptions. “Leather interior trim: Shale/Cocoa, Mini Perforated. This code identifies the factory upholstery material, color combination, or interior trim specification” is a reasonable plain-English reading, but the exact implementation should be verified for the 2021 model.

I have seen this on a similar Chevrolet Corvette. The basic description was correct, but one related feature was part of a separate package. I would not assume the code includes every item mentioned in marketing material.

I would start by checking the original build sheet and then compare the physical equipment on the vehicle. A sales or option code confirms the factory record, but it does not prove that every original component is still installed.

Some codes are reused across several brands, but that does not always mean the parts are identical. Model, trim, drivetrain, and production date can all matter.
