What is eBay Guaranteed Fit?

It is important to us that our buyers and sellers trust that parts and accessories sold on eBay Motors will fit the buyer’s vehicle as intended. To help sellers further enhance that trust and offer the best possible user experience, we have introduced eBay Guaranteed Fit.

eBay Guaranteed Fit is a program designed to protect buyers and sellers from challenges associated with fitment issues. This program applies to eligible items in eBay Motors’ Parts & Accessories category, including most parts and accessories for cars, trucks, and motorcycles.

How does eBay Guaranteed Fit work?

Buyer searches for the right part

When the buyer searches for a part or accessory using their vehicle details, we will check the vehicle details against item compatibility information in your listing through eBay’s fitment feature. When there is a match, fit is confirmed with a green checkmark green checkmark on the listing.

Buyer purchases an eligible part or accessory

When the buyer purchases an eligible part or accessory with the green checkmark, fit is guaranteed.

We’ll protect you for returns with fitment issues

If the item arrives and doesn’t fit the buyer’s vehicle, they can open a return request using the “Doesn’t fit my vehicle” return reason. If you choose to resolve it by accepting the return, the buyer will get a return label from eBay at no charge to you (exceptions may apply e.g. international shipping, oversized/freight items and multiple packages).*

How to participate?

Participation is optional. However, participation in the program may result in lower return costs and the enhanced buyer experience can generate more sales. If you want to take advantage of eBay Guaranteed Fit, ensuring your items are eligible is simple. Just follow these steps:

1. Add compatibility information to your listings.

Items listed in eligible categories that have compatibility information will be eligible for eBay Guaranteed Fit. Sellers can select which items to include in the program by completing the compatibility table. Learn more about parts compatibility listings.

2. Handle Returns

When a buyer opens a return under “Doesn’t fit my vehicle”:

- We will provide a free eBay label to the buyer if the return is auto accepted or if you manually choose to provide a free eBay label.

- If you are supported by a developer partner integrated with the Post-Order API to handle return requests, your partner must use the Process Return Request method of the Post-Order API to provide a Return Merchandise Authorization (RMA) number. The value of the decision field of that same request must be set to PROVIDE_RMA.

- You’ll be responsible for providing a way for the buyer to return the item.
