Vehicle Parts Compatibility

If you sell vehicle parts on eBay, you can match your vehicle parts & accessories to our catalogue, add parts fitment to your listings and keep on top of our Master Vehicle List (MVL) to give your listings the best chance at a sale.

What is vehicle parts compatibility?

When you create a parts and accessories listing, we recommend adding Parts Compatibility (also known as "fitment"). This allows you to add all the years, makes, models, trims, and engines that your part fits (up to 1,000 or 3,000 combinations, depending on the category), which makes it easy for buyers to find the right parts for their vehicle.

If your item is not vehicle specific such as sun shades or floor mats, please be sure to select “yes” in the ‘universal fitment’ item specific, which you can find in the Recommended or Additional section of your listing.

Why should you add fitment data to your listings?

Enabling fitment information for your listings helps buyers to easily find the correct products for their vehicles.

  • It increases your sales potential and visibility on eBay 
  • It better matches you with buyers searching for your items, and maps your listings to the vehicles buyers have saved in their eBay Garage 
  • Reduces the amount of returns and time spent managing customer queries and complaints

“Seller wdfzxy saw a 46% average year-on-year increase in sales after adding fitment data to their eligible listings*”

*Based on average YOY (2021 vs. 2020) sales uplift for 5 x weeks prior to and following eligible listing adoption. The growth in average sales of wdfzxy does not reflect or guarantee the potential growth in sales all sellers experience after adding fitment data. This may vary depending on various factors including your inventory, item pricing and sales activity.

How buyers search for vehicle parts on eBay

When searching for vehicle parts and accessories on eBay, buyers use the parts finder to ensure the products fit their vehicle. This filters the search to only relevant products. 

When they use the parts finder, their vehicle is saved to their eBay Garage, so they can filter any P&A search to only show products relevant to their vehicle in future.

[TIP] Completing as many item specifics as possible, including ‘Brand’ which is required, will allow us to match you with buyers in search. See more about item specifics.

How to add fitment to your listings

  1. Start by gathering information about the part or accessory. Make sure you have the Brand and Manufacturer Part Number (MPN), as well as the Make, Model and Variant to ensure buyers can find products that are compatible with their vehicles. You can use the Master Vehicle List (MVL) to compare the information you have about your item with the data used by eBay to create your listing.
  2. Decide how you’re going to list your product. You can list your products one at a time or in bulk using eBay tools or third-party tools.

Creating a single listing

Select Sell at the top of most eBay pages and create your listing as you would for any other item.

After you’ve told us what you’re selling and chosen the right category, be sure to enter the Brand and MPN. The MPN is a series of unique numbers and/or letters that are assigned to a part by the manufacturer. It identifies the part as belonging to and originating from that manufacturer. 

Next, select Add compatible vehicles and enter all the vehicle information you have for your item. At a minimum, include:

  • Make
  • Model
  • Variant

Buyers are searching for parts to fit their particular vehicles, so it’s important to be accurate when adding compatible vehicles, to avoid returns.

You can add up to 3,000 vehicles that your part is compatible with. You can use the Master Vehicle List (MVL) with Seller Hub Reports Tool to add parts compatibility data to your listings in bulk.

When you’re updating your listing, make sure to add as many recommended and optional item specifics as you can. These are based on frequently searched terms and help buyers to find your listings and understand exactly what you’re selling. 

Select Save when you’re done to return to the listing form.

Creating or revising multiple listings

Use the parts catalogue

If you sell in the Vehicle Parts & Accessories category, you have the option to adopt our parts catalogue. You’ll receive multiple benefits from adopting the Vehicle Parts & Accessories catalogue:

  • A faster and simpler listing process
  • Increased traffic to listings and potentially higher conversion
  • Improved visibility in search
  • Rich features like product reviews
  • Help potential buyers find the exact product fit for their needs

The catalogue allows sellers in most Vehicle Parts & Accessories categories to quickly list items using Brand, MPN or GTIN (UPC, ISBN, EAN) and add valuable data for buyers including images, item specifics and parts compatibility.

There are multiple ways to match your listings to the parts catalogue.

Master Vehicle List (MVL)

You can also manually choose up to 3,000 compatible vehicles per listing, from our Master Vehicle List (MVL), which includes over 40,000 vehicle models. You can use the MVL with Seller Hub Reports to add parts compatibility data to your listings in bulk. 

Assigning compatible vehicles to your listings makes it easier for buyers to find parts, and they can buy with confidence that they're buying a part that fits their model.

Even if you don’t match your listings to our catalogue, it’s still important to manually add compatibility information to your listings to boost your visibility in search, and avoid duplicate listings. 

If you can’t find a vehicle on our MVL, you can request it by emailing us at

Master Motorcycle List (MML)

If you list within the motorcycle parts categories, use the Master Motorcycle List (MML) so that buyers can refine their search by model to find your listing

You should use the MML when listing in the following Vehicle Parts & Accessories subcategories:

  • Motorcycle Parts (10063)
  • Motorcycle Tuning & Styling (96382)
  • Motorcycle Wheels & Tyres (35578)
  • Scooter Parts (84149) - later in 2016

To request the addition of vehicles that you believe may be missing from the MML, please send an email with the title “MML Missing Vehicle Request” to

Start Using Parts Compatibility

Step One: Learn how to get started using parts compatibility to boost your sales.

Step Two: Make sure your parts are visible on our Fitment Finder, using the elements you prepared in step 1. To check whether a category has fitment enabled, download our list of parts & accessories categories.

Avoiding Duplicate Listings

Avoid duplicate listings, by clearly demonstrating the difference between your items in the title, price, condition, photos, subtitles, item specifics (like MPN), and parts compatibility. 

If you’re selling the same part for different cars, use parts compatibility to avoid unintentional duplicates. If you list with variations, like colour, each variation should be a different product, with different MPNs. If the brand has the same MPN, create a listing for each variation specifying colour as an aspect.

How to Identify Duplicate Listings

We’d recommend identifying duplicates by viewing all of your active listings, and sorting by title or price + postage, to see similar items grouped together.

With Seller Hub Reports, you can export all of your active listings, sort, and edit in bulk. Make sure you check often to make sure you comply with our duplicate listings policy.

Removing Duplicate Listings

Removing duplicate listings ensures we remain a fair platform, and often results in a substantial increase in sales.  If we identify that you have duplicate listings, we’ll compare search scores, number of purchases, and time on site, and will remove the listing with fewer sales.
