PartsNumber is a professional parts catalogue for garages, workshops, parts retailers, fleet operators and vehicle dismantlers. It helps you identify a vehicle, find parts for its exact specification, and look up original part numbers, aftermarket equivalents and supersessions.
From identifying a part to choosing a supplier: compare vehicle compatibility, prices, stock availability and delivery lead times to prepare an order for repairs, fleet maintenance or a customer sale.
Start by identifying the vehicle. A VIN search helps determine its specific variant and open the relevant catalogue. When searching by specifications, you can select the make, model, year of manufacture, engine, vehicle specification and other available characteristics.
This helps account for differences between variants: vehicles of the same model may have different brakes, suspension, engine components and other assemblies. PartsNumber brings together catalogues for passenger cars, commercial vehicles and special equipment.
Once you have selected the vehicle or equipment, browse the relevant assembly or category, locate a part in a diagram, or search by its description. Diagrams show where a part fits within an assembly and help identify related items such as fixings, seals and adjacent components.
The original part number is the starting point for further searches and offer comparisons. Always check the catalogue notes and any fitment restrictions when selecting a part.
PartsNumber helps you check aftermarket equivalents and cross-references for a selected part, and find information about superseded original part numbers. This is useful when the original part is unavailable or you want to offer a customer a choice of brands and prices.
A cross-reference links parts from different manufacturers. Before making a final selection, compare the specifications and check that the part fits the exact vehicle specification.
Match the part you have identified to available supplier offers and compare prices, stock availability and delivery lead times. Urgent repairs call for faster delivery, while scheduled maintenance gives you more flexibility to balance cost and lead time.
Consider the supplier’s location and delivery conditions for your region. Prices, stock levels and lead times depend on supplier offers and how frequently they are updated. Confirm the current terms before placing an order.
Garages and workshops can use the catalogue to identify parts for repairs and servicing. Parts retailers can answer customer enquiries and compare genuine parts with aftermarket equivalents. Fleet operators can find parts for their own vehicles. Vehicle dismantlers can identify the part numbers of removed components and check which vehicles they fit.
Search methods, diagrams and available information vary by brand and catalogue. Before subscribing, check your vehicles or equipment in the catalogue directory and confirm coverage for the models and years you work with.
