How to Find Your OEM Part Number: Step-by-Step Guide

A practical guide to locating your vehicle OEM part number — from reading part markings to using VIN decoders and online catalogues.

Finding the correct OEM part number is the most reliable way to ensure you order exactly the right component for your vehicle.

Method 1: Read the Original Part

The easiest method is to read the part number directly from the component you are replacing. Most OEM parts have the part number stamped, moulded, or printed on them.

Method 2: Service Manual

Your vehicle official service manual contains part numbers for every serviceable component. Many manufacturer parts catalogues are also available online.

Method 3: Search on JustOEM
