Every used Japanese truck has a chassis number, also called a frame number, and this number plays a major role in export procedures. Global buyers often focus on engines, mileage, and condition. However, the chassis number is just as important because it confirms the truck’s identity and prevents problems at customs.
Moreover, understanding this number helps buyers avoid delays, incorrect paperwork, and unexpected fees.

1. What Is a Chassis Number?
A chassis number is a unique identification code stamped on the truck’s frame.
Although many countries use a 17-digit VIN, Japanese trucks often use model-based frame numbers instead.
A typical Japanese chassis number includes:
-
Model code (e.g., FD1J, FRR90)
-
Serial number
-
Sometimes a production code
This combination confirms exactly which truck you are buying.
2. Where to Find the Chassis Number
You can locate the frame number in several places:
-
Stamped on the right front frame rail
-
On the export certificate
-
On the auction inspection sheet
-
On the cab plate inside the door
Because each location should match, buyers should request photos of all identification areas.
3. Why the Chassis Number Matters for Export
The chassis number connects every export document.
If the number is incorrect, customs officers may stop the shipment.
Additionally, a mismatch can cause delays, storage fees, or rejected documents.
The chassis number is used in:
-
Export Certificate
-
Bill of Lading
-
Commercial Invoice
-
Insurance papers
-
Customs declarations
Therefore, global buyers should check the number early.
4. How to Read a Japanese Chassis Number
Japanese truck frames often start with a model code.
For example:
FRR90-123456
-
FRR90 = Model
-
123456 = Serial number
This structure helps identify the exact series, engine class, and generation.
Furthermore, it helps buyers order the correct spare parts later.
5. Common Issues Buyers Face
Even experienced importers sometimes face problems.
Below are the most common issues:
1. Incorrect digits
One wrong number can stop customs clearance.
2. Rust covering the stamp
Outdoor storage sometimes hides the frame number.
Buyers should request a clear, close photo.
3. Confusion with VIN
Some markets expect a 17-digit VIN.
Japanese trucks may use shorter frame numbers instead.
4. Typing mistakes in documents
A small error on the Bill of Lading can cause serious delays.
Because of these risks, buyers should confirm the number several times.
6. How Exporters Verify the Chassis Number
Professional exporters follow strict checks:
-
Clean the frame area
-
Take high-resolution photos
-
Confirm export certificate matches the stamp
-
Double-check invoice and BL
-
Provide photos to international buyers
These steps create a smooth export process.

Compare it with all documents
