Platform-led numbering
A Mazda number opens with the platform code — BP, KD, GJ, ND — followed by the assembly group and the part. In BP4K-34-380, BP identifies the platform family, 34 is the suspension group and 380 the component within it.
That leading block is genuinely useful at the counter: it tells you which car family the part was designed for before you check anything else. A number opening with ND belongs to the MX-5 of that generation, and if the car in front of you is a CX-5, something has gone wrong upstream in the conversation.
Where Mazda variants split
Market is the main driver. European, North American, Japanese and Australian builds of the same model differ in emissions hardware, lighting and restraint systems, and Mazda's mid-cycle updates are frequent enough that build date decides more often than model year.
Skyactiv-X and the diesel engines add their own splits in the fuel, intake and after-treatment groups, which is exactly the area where ordering against the model name rather than the VIN produces a part that looks right and is not.
Japanese-market cars
Mazdas built for the Japanese domestic market carry a chassis number in the local format rather than a seventeen-character VIN. For an import, that is the identifier that reaches the factory build; a VIN issued at registration in the destination country identifies the same car through a different system.
Common Mazda nameplates
These nameplates help you find the right vehicle family. Confirm the exact model, market and production period against the active catalog before quoting a part:
| Model | Production years |
|---|---|
| Mazda Mazda3 | 2019–present |
| Mazda CX-5 | 2017–present |
| Mazda Mazda6 | 2012–present |
| Mazda CX-30 | — |
| Mazda MX-5 | — |
| Mazda BT-50 | — |
Frequently asked questions
What does the first block of a Mazda part number mean?
It is the platform code — BP, KD, GJ, ND and so on — identifying the car family the part was designed for, before the assembly group and the component itself.
Does the catalog cover Japanese-market Mazdas?
Yes, resolved by the chassis number those cars carry rather than by a seventeen-character VIN. On an import, the chassis number is what reaches the factory build data.
How current is the data?
It is read online rather than from an installed copy, so supersession chains stay in step with the factory instead of freezing at an install date.
