Interior Trim Code Car Guide: Where It Is, What It Means
Interior trim code car guide: where the code sits, how it differs from trim level, and how to use it to match seats, panels and dye without guesswork.
Yes, there is a code for the inside too. For anyone searching "interior trim code car," the short answer is this: it is the manufacturer's short code for the factory interior color, and on some vehicles the upholstery material or seat type as well. On many vehicles it is printed on a label in the driver's door jamb, often right next to the exterior paint code, and on others it sits on an options label in the glove box or trunk. It helps you match seats, panels and dye, but it identifies a color scheme, not a specific part, so you usually need a part number as well.
This article explains where to find the code, how to avoid confusing it with two other things called "trim," and how to use it when you are hunting for a matching interior piece.

"Trim" means three different things on a car
A lot of confusion starts with the word itself. When people say trim, they mean one of three things:
- Trim level. The version of the model, such as a base, mid or top grade. It sets the equipment list. Our guide on how to tell what trim your car is covers that meaning.
- Interior trim code. The code for the cabin's color scheme and, on some vehicles, its material. That is this article.
- Trim pieces. The physical parts: door panels, pillar covers, console surrounds, kick panels. You buy these by part number.
An interior trim code links meaning 2 to meaning 3. It tells a parts counter or a salvage yard which color family of trim pieces your car was built with. It does not, by itself, say which door panel design or seat shape fits your car. Those depend on the model, the trim level and the build date.
Where the interior trim code on a car is printed
There is no single standard location, and that is not an accident. In the US, the federal certification label rule, 49 CFR 567.4, lists what the manufacturer's certification label must carry. According to the text of 49 CFR 567.4 published by Cornell's Legal Information Institute (read September 27, 2026), the required items are the manufacturer's name, the month and year of manufacture, the gross vehicle weight rating, the gross axle weight rating for each axle, the VIN, a statement of conformity with federal safety standards, and the vehicle type. The same rule places that label on the hinge pillar, the door-latch post or the door edge next to the driver, or on the left side of the instrument panel if none of those works.
Paint and interior trim codes are not on that list. When a manufacturer prints them on the door jamb label, it is choosing to. That is why the field names, the order and even the location differ between brands.
Common places to look:
- The driver's door jamb label. Many manufacturers print a paint code and an interior trim code together on this label. The trim field may be labeled with something like "TR," "TRIM" or "INT," sometimes as part of a combined color and trim field. Our line-by-line guide to door jamb sticker meaning explains how to read the other fields around it.
- An options or parts identification label. Some manufacturers put a list of option codes on a separate label. On GM vehicles this is the Service Parts Identification label, often in the glove box or the trunk area, and the interior color appears among its codes. Our article on GM RPO codes shows where to find that label and how to read it.
- Under the hood or on the firewall. Some older vehicles used a data plate in the engine bay.
If you find two short codes side by side and are not sure which is which, the one that looks up as an exterior color is the paint code. The other is very likely the trim code.

What the code actually tells you
The information packed into an interior trim code varies by manufacturer and by era. In general:
- Color is almost always part of it. The code identifies the factory interior color scheme, which may cover the seats, carpet, dash and door panels together.
- Material is sometimes part of it. On some vehicles the code also distinguishes cloth, vinyl or leather, or a particular seat configuration. On others, material is a separate option code.
- The meaning is specific to the maker, and often to the model and year. The same letter or number can mean different things on different vehicles. A code chart for one model year is not safe to apply to another.
Because of that last point, we do not publish tables of what individual trim codes mean. Any such table is only correct for the exact make, model and year it was built from, and code charts copied from one website to another are a common source of wrong answers. The safe sources are the manufacturer, a dealer parts department and your own vehicle's documents.
Using the code to find a matching interior part
This is the reader's real problem: a torn seat, a cracked door panel, a faded console lid, and a need for a piece that matches. Here is how the code fits in.
Step 1: Record the code and the vehicle details
Write down the interior trim code, the full VIN, the model year and the build date from the label. The build date matters because colors and materials can change during a model year.
Step 2: Get the part number, not just the color
The trim code narrows the color. The part number identifies the piece. A dealer parts department can look up the exact part for your VIN, and on many interior parts the color is reflected in the part number or its listing. Salvage yards and interchange services also search by part number and color.
Step 3: Check the color name, too
The original window sticker usually names the interior color and material in words. That name is a good cross-check against the code, in the same way a paint color name is a cross-check against a paint code. A build sheet can go further and list option codes. See how to get a build sheet for your car for the options by manufacturer.
Step 4: Compare the actual part before fitting
Interior colors are not always consistent across materials. A plastic door panel, a vinyl armrest and a cloth insert in the "same" color can look slightly different from each other when new, and years of sun can move them further apart. Compare a replacement piece against the car in daylight before committing to it, especially if it is used.

Interior trim codes and upholstery repair
Upholstery shops, dye suppliers and seat cover makers often ask for the interior trim code. It helps them start from the right color family. A few honest limits apply:
- Dye and repair kits are matched to a color, and your interior may have moved away from it. Sun-exposed surfaces such as the top of the dash, the rear parcel shelf and the outboard seat bolsters usually fade faster than surfaces in shade. A dye mixed to the factory color may be darker than your faded seat.
- Texture is not in the code. Grain patterns on vinyl and leather, and weave patterns on cloth, are part of the look. Two pieces in the same color with different textures will not look like a match.
- Suppliers may use their own cross-reference numbers. Some upholstery and dye suppliers keep their own codes for factory colors. Ask the supplier how they map your manufacturer's trim code, and whether they can match from a physical sample instead.
When the match matters, many upholstery suppliers can work from a sample: a small piece from a hidden area, or a removable part you can send or bring in. That is often more reliable than any code, for the same reason a body shop matches paint to the car and not only to the paint code.
When the code is missing or unreadable
Door jamb labels get painted over, damaged or replaced. If you cannot read the trim code:
- Check other labels. Look in the glove box, the trunk and under the hood for an options or parts identification label.
- Ask a dealer parts department. With the VIN, a dealer can usually look up the factory interior color.
- Check the original window sticker or build sheet. Either may name the interior color and material.
- Look at the car. Hidden areas, such as under seats or behind trim panels, often show the original color more accurately than faded, visible surfaces.

Frequently asked questions
What is an interior trim code on a car?
It is a short manufacturer code identifying the factory interior color scheme, and on some vehicles the upholstery material or seat type. It is used to match seats, panels, carpet and dye.
Where is the interior trim code located?
On many vehicles it is on the driver's door jamb label near the paint code. Others print it on an options label in the glove box or trunk, or on an engine bay data plate on some older vehicles. A dealer can look it up from the VIN.
Is the interior trim code the same as the trim level?
No. The trim level is the version of the model and its equipment. The interior trim code describes the cabin's color and sometimes its material. A car has both.
Can I order a door panel using only the trim code?
Usually not. The trim code narrows the color, but you also need the part number for the specific piece, which depends on the model, trim level and build date. A dealer parts department can find it from your VIN.
Why doesn't my replacement interior part match even with the right code?
The original may have faded, the new part may be a different material or texture, or the code may have covered a color family rather than one exact shade. Compare parts in daylight before fitting.
