How To Find The Right Car Part By Registration Or VIN
Car Parts Centre · 1 August 2026
Reg, VIN and OE number searches compared — and how to be certain a part fits before it ships.
Registration lookup is the quickest way to shop, but it identifies a vehicle record, not always a single engine or brake variant. Knowing when to fall back to VIN or an OE number saves returns.
Searching by registration
Enter the plate and we match it to the manufacturer, model, engine and build year, then filter the catalogue to parts listed for that vehicle. Where a plate matches more than one variant — common with facelift years and multiple brake-disc diameters — we show the options rather than guessing for you.
When to use the VIN
The 17-character VIN, found on the windscreen base, door pillar or V5C, identifies the exact build. Use it for imports, personalised plates, vans with multiple payload versions, and any car where the plate search returns more than one match.
Searching by OE number
If you have the old part in your hand, the number cast or printed on it is the most reliable search of all. Enter it in the search bar and we return the matching aftermarket equivalents with their cross-references, so you can compare brands on a like-for-like basis.
Final fitment checks
Before ordering, compare the critical dimensions against the old part: disc diameter and height, filter thread and gasket size, sensor cable length and connector shape. If anything is unclear, call our customer service team on 07779 454554 with your reg or VIN and we will confirm it.
Frequently asked questions
Why does my reg show two options?
Because the DVLA record does not always distinguish engine or brake variants. Choosing the right one, or entering the VIN, resolves it.
Is an aftermarket part as good as OE?
Many aftermarket brands are the original equipment supplier selling under their own label. The OE cross-reference on each product page shows the equivalence.
What if the part still doesn't fit?
Contact us within 30 days with the part unused and in its original packaging and we will sort a replacement or refund.
