An OEM number identifies a part in the car manufacturer's catalogue. Think of it as the part's precise name: it helps you find the right version.
Where to look for a part number
On the box: a label with a number
On the part: a sticker or housing marking
In an earlier order: the part-number field
A part-number line can look like this
Part No.AA-12345-BIllustrative example. Look for the full number beside Part No., not a barcode or date.
What to do, step by step
Find the part-number marking
Look for OEM, OE, Part No., P/N or a part-number label. Part No. on an aftermarket box may identify that manufacturer's article rather than the car maker's OEM number. Photograph the whole label, including the brand.
Enter the complete number
Type every letter and digit in the search below, including the final letters. Spaces and hyphens can stay. Do not substitute a barcode or batch number for the part number.
Check it against your vehicle
Open the result and give the manager your make, model, year and a photo of the number. A similar picture or partial number match does not establish compatibility.
Copy the number from your own part or box. Do not enter the teaching example AA-12345-B.
More detail and common mistakes
- Check the removed part, packaging label and previous order records. Photograph the complete number, including letter suffixes.
- Enter the number in KRONIS search. Spaces and hyphens are normalised. A partial article search helps find options, but the full number still needs checking.
- Check whether the number has been superseded and matches your configuration. A moulded housing number may identify only the housing rather than the complete assembly.
