The Best myFitment Alternative: Save Fitment Data and Manage Fitment Without Skipping a Beat

For eBay Motors sellers, vehicle compatibility data is how buyers find their listings. If you've relied on myFitment to manage that data, September 30, 2026 is the last day it will be available. eBay is shutting down myFitment, and is not providing sellers a way to export their managed fitment data before the service closes. For sellers looking for a myFitment alternative, starting your search and migration early can save you hours of fitment research, piecing together data, and manually copying lists, and can help you ensure that you maintain control over your listings' fitment data even after myFitment is no longer available for eBay Motors listings.

In this guide, we'll explain exactly what you can expect to stop working after the shutdown, how to recover the compatibility data that's already on your listings, and whether eBay's Fitment Plus Auto program really works as a myFitment alternative on its own. We'll also cover how to copy, generate, and save compatibility lists with 3Dsellers, so you have a working process in place before myFitment becomes unavailable.

Why myFitment Is Shutting Down

eBay has decided to shut down myFitment on September 30, 2026, as part of a broader shift toward its own native tools, such as the Fitment Plus Auto program. Below, we'll cover what stops working after the closure and what happens to the fitment already on listings.

What Stops Working When myFitment Shuts Down

After September 30, myFitment will stop handling fitment data on your behalf. It will no longer:

• Send new fitment data to marketplaces, providers, or partners
• Process new fitment submissions
• Submit updates or corrections
• Monitor whether submissions were accepted

If you currently use myFitment to add or fix compatibility on eBay listings, you'll need a new process in place before that date.

What Happens to Fitment Already on Your Listings

Fitment already applied to listings may remain after the shutdown — heavy emphasis on may, as myFitment does not guarantee that existing fitment data currently on live listings will not be affected by the shutdown. Furthermore, myFitment will no longer manage, update, correct, or monitor compatibility and fitment data once the service closes.

Exporting myFitment Data Without an Export Tool

For sellers who have spent years building compatibility lists in myFitment, the obvious and most pressing question is how to keep their data after the service closes. Unfortunately, myFitment will not provide or support a data-export or migration tool as part of the shutdown, so you'll need another way to keep a copy of your fitment records.

Luckily, the fitment data published by myFitment to eBay doesn't exist only in myFitment — it's still right there on your eBay listings. In our experience working with eBay Motors sellers, the compatibility information on live listings is often the most complete fitment data for every part, making it an incredibly valuable asset for their eBay Motors business. 3Dsellers helps you keep that data yours and independent of myFitment by enabling you to copy the compatibility currently on your listings and save it for future use (more on that below).

It's important to keep in mind that a copied list reflects the fitment data on the listing at the time of copying, including any vehicles added by Fitment Plus Auto. Additionally, opting out of Fitment Plus Auto removes any compatibility the program added. For these reasons, it's important to copy your lists before September 30, while myFitment is still managing them and before you opt out of Fitment Plus Auto.

Is Fitment Plus Auto a Reliable myFitment Alternative for eBay Sellers?

Fitment Plus Auto is eBay's built-in program that automatically adds fitment data to Parts & Accessories listings, and it will be your default option as an eBay seller after myFitment shuts down. Below, we'll take a look at how eBay's Fitment Plus Auto program works, and examine cases where sellers might want more control over their compatibility data lists.

How Fitment Plus Auto Works

In October of 2025, eBay automatically enrolled all sellers with listings in fitment-enabled categories in the Fitment Plus Auto program. The program updates Parts & Accessories listings using an eBay-maintained database, adding compatibility data to listings automatically. To match vehicles, Fitment Plus Auto relies on each listing's brand and part number, so it's important to keep both of those details accurate for every part in your inventory.

Sellers can opt out at any time, but opting out removes all compatibility data that Fitment Plus Auto added to listings. If you plan to opt out, make sure to copy and save the compatibility data from your listings before you do.

Where Sellers Still Need More Control

Because Fitment Plus Auto adds and updates compatibility on its own, it's easy to assume that the responsibility for accurate information lies with eBay. However, eBay places responsibility squarely on sellers for the fitment on their listings, and recommends reviewing that fitment info regularly to check for inaccuracies. For many sellers, this makes Fitment Plus Auto less than ideal for keeping the fitment data on their listings updated.

Compatibility also plays a role in eBay Guaranteed Fit, which uses fitment data on the listing to help buyers find parts that fit vehicles in their My Garage. Listings qualify for the program when they include compatibility information, which eBay uses to confirm fit. If a part matches a buyer's vehicle, they'll see a green checkmark on the listing, indicating that it's a guaranteed fit. If Fitment Plus Auto adds an incorrect vehicle to a listing, however, a buyer might see the checkmark and end up purchasing a part that won't fit. When that happens, you're liable for the return cost, have to eat the account defect, and have no recourse in the event of negative feedback.

For these reasons, many sellers who primarily sell car parts and accessories prefer to manage their products' fitment data on their own, independent of Fitment Plus Auto. That way, they're not liable for any mistakes in eBay's database, and always know what fitment information is on their listings at any given time.

3Dsellers as a myFitment Alternative for eBay Motors

For sellers who want to maintain control over their listings' fitment data, the myFitment shutdown means finding a new way to review and manage compatibility. In practice, this comes down to two tasks: saving the current compatibility information already on live listings before myFitment shuts down, and building accurate lists for new parts going forward. In this section, we'll understand how 3Dsellers' eBay Motors tools can help you do both, so you can copy, generate, and save compatibility lists without relying on myFitment or Fitment Plus Auto.

Copy Compatibility Lists by Item ID or VIN

3Dsellers can copy a listing's full compatibility list using only its eBay item ID, making it easy to save the fitment from your live listings before myFitment shuts down. The copied list includes every vehicle currently on the listing, including those myFitment added. For sellers with very large inventories, compatibility lists can also be copied in bulk through a CSV file.

Pro Tip: The item ID copying feature also works on other sellers' listings, which is useful when you want to list a part that a competitor is already selling. Rather than building a compatibility list from scratch, you can use theirs as a starting point and it to match your part!

In addition to copying from live listings and compiling compatibility lists from CSVs, 3Dsellers can also build a compatibility list from vehicle identification numbers (VINs), which is helpful when you're working from specific vehicles. The tool decodes each VIN and adds the vehicle to the compatibility list if eBay supports it for that category.

Auto-Generate Fitment With AI

For parts that don't have a compatibility list yet, 3Dsellers can auto-generate fitment with AI. 3Dsellers' AI analyzes the part and suggests fitment rows, which you can then review and add to the listing if they're a match.

Save and Reuse Lists with Compatibility Presets

Once you've recovered compatibility from your listings, compatibility presets give you a place to keep those lists for future use. A preset is a saved compatibility list stored at the account level within 3Dsellers, allowing you to apply it to any listing or product, not just the one where it was created. This is especially useful for sellers who list the same part, or parts that fit the same group of vehicles, on a regular basis. Rather than rebuilding a list each time, you can load a saved preset into a new listing or apply it to many existing listings at once.

Compatibility lists can also be downloaded as CSV files, which gives sellers a backup copy to store outside of 3Dsellers.
