Reading a Honda part number
Honda numbers have three blocks: five digits for the part type, three for the model code, and two or three for the variant. In 45022-TVA-A00, 45022 is a front brake pad set on any Honda car, TVA identifies the model — an Accord of that generation — and A00 is the specific variant and revision.
The first block is the constant, and it is worth learning a handful: 45022 front pads, 43022 rear pads, 15400 oil filter, 17220 air filter. Knowing them lets you sanity-check a supplier's quote in seconds — if the part type block does not match what you asked for, the conversation has gone wrong before any money moved.
The middle block is where Honda and Acura meet. Shared platforms carry the same model code, which is why an Acura part number frequently identifies a component fitted to a Honda as well.
Frame numbers on Japanese-market cars
A Honda built for the Japanese domestic market carries a frame number rather than a seventeen-character VIN — a model code, a hyphen and a serial, such as CL7-1234567. It is not a VIN, it has no check digit, and pasting it into a field expecting seventeen characters will not resolve.
For an import, the frame number is the identifier that reaches the factory build; a VIN issued at registration in the destination country identifies the same car by a different system. Both can be correct, and the catalog wants the one the factory used.
Where Honda variants split
Honda's parts splits are driven less by option codes than by market and production date. The same generation of Civic built for Europe, North America and Japan differs in suspension, lighting, emissions hardware and restraint systems, and mid-cycle running changes are frequent enough that build date decides more often than model year does.
Hybrid and electrified models sit in the same catalog: what changes is which assembly groups exist, not how you navigate to them.
Common Honda 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 |
|---|---|
| Honda Civic | 2021–present |
| Honda CR-V | 2017–present |
| Honda Accord | 2017–present |
| Honda Jazz | 2020–present |
| Honda HR-V | — |
| Honda Pilot | — |
Frequently asked questions
Does the Honda catalog cover Acura?
Yes. Honda and Acura share one catalog and, on shared platforms, share part numbers — the middle block of the number carries the model code regardless of which badge the car wears.
Why will my Honda number not resolve?
The most common reasons are a Japanese-market frame number entered as a VIN, a superseded number the catalog has retired, or a transcription slip. Working forward from the VIN or frame number is always more reliable than working back from a number.
What do the three blocks of a Honda number mean?
Five digits for the part type, three for the model code, two or three for the variant and revision. The part-type block is constant across the whole range, so 45022 is a front brake pad set on any Honda.
