Rating: 4.5/5 stars

Understanding a Toyota vehicle goes beyond its nameplate. Behind every Corolla, Camry, or Land Cruiser is a specific Katashiki code—a fundamental "DNA string" used by Toyota to categorize its products. What is a Katashiki Code?

The term Katashiki (型式) literally translates from Japanese as "model" or "product type". In Toyota's internal and service systems, it refers to a group of vehicles that share the same core descriptive factors and classifications, such as generation, engine family, and body style.

While many owners confuse it with the 17-digit Vehicle Identification Number (VIN), the Katashiki is actually a shorter, more descriptive model code found within the VIN or on the vehicle’s manufacturing plate. Anatomy of the Model Code

A Katashiki code typically combines letters and numbers to represent the vehicle’s technical specs. For example, in a code like ZZT231 (a 7th Gen Celica):

Engine Family: The first letters (e.g., "ZZ") identify the engine series used.

Platform/Series: The following letter (e.g., "T") identifies the chassis platform.

Generation/Variation: The numbers (e.g., "231") specify the generation and drivetrain configuration. How to Find Your Katashiki

If you are using tools like the MyToyota App or ordering specific spare parts, you may be asked for this 6- or 7-digit code. You can find it in several places:

VIN Plate: Often located on the driver-side doorjamb or the dashboard. The 7th digit of a modern Toyota VIN is often specifically labeled as the "series" or "katashiki". toyota katashiki code

Manufacturing Sticker: A white or silver sticker on the door frame often lists the "MODEL" followed by the full Katashiki string.

Registration Documents: Depending on your country, it may be listed under "Model Code" on your vehicle's V5C or title. Why It Matters

For enthusiasts and mechanics, the Katashiki is the most accurate way to verify a vehicle’s true identity. Because Toyota often produces different versions of the same car for different regions, the model name alone isn't enough to ensure a part will fit. Knowing your Katashiki ensures you are looking at the correct technical specifications and service history for your exact build. If you'd like, let me know: The model name of your Toyota The year it was made

A Toyota Katashiki (型式) code is the official internal model designation used to identify a vehicle's specific configuration, including its engine type, body style, and transmission. Unlike a Vehicle Identification Number (VIN), which is unique to a single car, the Katashiki code is shared by all vehicles produced with identical technical specs. 1. Where to Find the Code

The Katashiki code is typically found on the Manufacturer's Identification Plate (Model Plate).

Location: Usually located on the driver-side door jamb, the firewall inside the engine bay, or near the radiator.

Appearance: It is often labeled as "MODEL" and consists of a string of alphanumeric characters (e.g., ZRE182L-GEXNKW). 2. Breakdown of a Katashiki Code

While the exact sequence varies by era and region, a modern Katashiki code is generally divided into two main parts: The Basic Model Code (The First 5–7 Characters)

This identifies the core platform and powertrain. For example, in ZRE182: ZRE: The engine family (ZR series engine).

182: The platform or chassis generation (Corolla/Auris 180 series). The Extension (The Suffix)

The characters following the dash provide the granular details:

Steering Position: L for Left-Hand Drive, R for Right-Hand Drive. Transmission Type: Identifies Manual, Automatic, or CVT.

Trim Level/Grade: Distinguishes between base models (like LE) and sport or luxury trims (like XLE/XSE).

Engine Specification: Indicates if the engine is naturally aspirated, turbocharged, or hybrid.

Destination/Region: Codes that tell Toyota whether the car was built for Europe, North America, or General markets. 3. Why It Matters

Parts Accuracy: When ordering mechanical parts (like sensors, gaskets, or suspension components), the Katashiki code is often more accurate than the "Year/Make/Model" because it accounts for mid-year production changes.

Tuning and Modifications: Enthusiasts use these codes to identify specific "desirable" chassis or engine combinations (e.g., the AE86 for the Corolla or JZA80 for the Supra).

Recall Identification: Service departments use these codes to quickly determine if a specific production run is affected by a technical service bulletin. 4. Example: Toyota Hilux (GUN125R-DTFLHQ) GUN125: Indicates a 4WD Hilux with a 1GD-FTV engine. R: Right-hand drive. D: Double cab body style. T: 6-speed automatic transmission.

Do you have a specific code from a vehicle's door jamb that you would like me to decode for you?

Katashiki code is an alphanumeric model designation system used by Toyota to identify a vehicle's exact technical configuration, including its engine, platform, body style, and factory options. Unlike the 17-digit Vehicle Identification Number (VIN)

, which is a unique serial number for a specific car, the Katashiki code is a more general "type code" that describes the vehicle's specific build parameters. Understanding the Katashiki Structure

The Katashiki code typically consists of a prefix representing the engine and platform, followed by a suffix that details specific factory options. Engine & Platform Prefix:

This is the most recognisable part of the code. For example, in the code I'm assuming you're referring to the Toyota Katashiki

, 'A' refers to the 4A series engine, and 'E86' refers to the Corolla/Sprinter chassis. The Full Model Designation: A complete Katashiki code is often longer, such as ST202R-BLMGFW . This specific string provides a breakdown of: Trim Level: Often indicated in the middle letters. Body Style: Whether it is a 2-door or 4-door vehicle. Transmission & Drivetrain: Identifies manual vs. automatic and 2WD vs. 4WD. Steering Position: For example, 'R' often denotes Right-Hand Drive (RHD). Toyota UK Magazine Katashiki vs. VIN

While both are used for identification, they serve different purposes within the Toyota Global Information System

Decoding the Toyota Katashiki: A Guide to Understanding Your Vehicle’s DNA

If you’ve ever looked at the manufacturer’s plate on your Toyota—usually found on the door jamb or under the hood—you’ve likely seen a string of alphanumeric characters labeled "MODEL." While many owners focus on the VIN (Vehicle Identification Number), enthusiasts and mechanics often look for the Katashiki code.

In Japanese, Katashiki (型式) literally translates to "model type" or "form." For Toyota, this code is the definitive blueprint of your vehicle’s build. What is a Toyota Katashiki Code?

While a VIN is unique to a single specific car, a Katashiki code describes a specific configuration of a model. It tells you exactly which engine, transmission, body style, and trim level was assigned to that production run.

For example, two Toyota Corollas might look identical on the outside, but one might be a ZRE172L-GEXGKA while the other is a ZRE172L-GEXNKA. That one letter difference could mean the difference between a 6-speed manual and a CVT transmission. How to Read the Code

A Katashiki code is usually broken down into several sections. While the length can vary depending on the era and market (JDM, USDM, or Europe), it generally follows this logic: 1. The Engine Family (The First Letters)

The leading characters typically identify the engine series installed in the car.

AE86: Features the A-series engine (specifically the 4A-GE).

GRN285: Features the GR-series V6 engine (found in modern 4Runners).

URJ201: Features the UR-series V8 engine (found in the Land Cruiser/LX570). 2. The Chassis/Platform (The Numbers)

The numbers following the engine code denote the chassis generation and drivetrain.

In a ZN6, the "6" represents the first generation of the 86/BRZ platform.

In a UZJ100, the "100" represents the 100-series Land Cruiser. 3. The Configuration Suffix (The Letters After the Dash)

This is where the detail gets granular. The string of letters after the dash (e.g., -AHMXHA) identifies:

Steering Position: L for Left-Hand Drive, R for Right-Hand Drive. Trim Level: Specific codes for DX, LE, XLE, or TRD Pro.

Transmission: Identifies whether it’s a 4-speed auto, 6-speed manual, or CVT.

Market Destination: Codes that specify if the car was built for North America, Europe, or General Export. Why Does the Katashiki Matter?

For the average driver, it might seem like trivia. However, for specific tasks, it is essential:

Ordering Parts: Many Toyota parts catalogs are organized by Katashiki. Using this code ensures you get the exact radiator, wiring harness, or sensor meant for your specific engine-transmission combo.

Modifying Cars: Enthusiasts use these codes to identify "ideal" donor cars for swaps (e.g., hunting for a specific "G" grade transaxle).

Importing JDM Cars: When buying a vehicle from Japan, the Katashiki confirms the "grade" of the car, helping you verify if a Supra is a genuine Turbo (JZA80-ALFQZ) or a naturally aspirated model. Where to Find Your Katashiki One letter (e

You can find this information on the ID Plate (Build Plate).

Driver’s Side B-Pillar: Open the driver's door and look for a black or silver sticker/plate.

Firewall: Inside the engine bay, usually bolted to the metal wall separating the engine from the cabin.

The "MODEL" Line: Look specifically for the word "MODEL" followed by the alphanumeric string.

The Toyota Katashiki is more than just a label; it’s a detailed map of a vehicle's mechanical identity. Whether you are a restorer looking for period-correct parts or a hobbyist trying to understand your car's lineage, mastering these codes allows you to "speak" Toyota’s internal language.

Are you looking to decode a specific Katashiki string for a vehicle you currently own?

The Toyota Katashiki code is a specialized model identification code used by Toyota to define a vehicle's exact configuration, including its engine, drivetrain, body style, and market specifications. Unlike the 17-digit Vehicle Identification Number (VIN) which is a unique "fingerprint" for a single car, the Katashiki code is a model code shared by all vehicles built to the same set of technical specifications. Core Components of the Katashiki Code

The code typically consists of a string of alphanumeric characters (often 6–12) that can be decoded to reveal technical details:

Engine & Platform: The first few letters usually represent the engine family and the vehicle platform. For example, in the code ST202R-BLMGFW, the "ST202" identifies the engine type and chassis series.

Drive Configuration: Specific letters indicate whether the car is front-wheel drive, rear-wheel drive, or four-wheel drive.

Body & Trim: Later characters in the string designate the body type (e.g., sedan, hatchback) and the trim level or "grade".

Transmission & Destination: The final characters often identify the transmission type (manual vs. automatic) and the specific market or region the car was built for. How to Find the Katashiki Code You can generally locate this code in the following places:

The VIN Plate: On many Toyotas, the Katashiki (or "Model") code is stamped directly onto the same metal identification plate as the VIN, often found on the firewall in the engine bay or on the driver-side doorjamb.

Manufacturer Sticker: Look for a white tamper-proof sticker on the door shut line that lists the "Model" followed by the Katashiki string. Why It Matters

Parts Accuracy: Because a single model year can have multiple engine or drivetrain variations, the Katashiki code is often more reliable than the VIN for ordering specific OEM replacement parts.

Service History: Toyota service centers use this code to verify the exact build specs for maintenance and recall information.

Import/Export: It is essential for verifying vehicle eligibility and specifications when importing Japanese Domestic Market (JDM) vehicles to other countries.

Here’s a quick guide to Toyota Katashiki codes — the internal model codes Toyota uses to identify specific vehicle chassis, body styles, engines, and drivetrains.

How to find your Katashiki code

Part 9: The Future of Katashiki Codes

With Toyota moving toward the TNGA (Toyota New Global Architecture) platform and global VIN standardization, the traditional JDM Katashiki is becoming less common on new cars sold in the West.

However, the Model Code lives on. A 2023 Toyota Corolla Hybrid might have a code like MXWH60L.

For collectors and importers of 80s, 90s, and 2000s JDM legends, the Katashiki will never die. It is the secret handshake of the Toyota community. If you own a Supra, a Chaser, a Crown, a Celsior (LS400), or an Aristo (GS300), you need to memorize your Katashiki code. Put it in your phone. Write it on a sticky note in your glovebox.
