Providing and adding fitment data

How to submit fitment data

Directly providing fitment data to Amazon Automotive requires integration as a fitment data provider, which utilizes Amazon's Seller Central as a pipeline for transferring fitment/application/ACES data. As a seller, you will need a separate Seller Central account from your main account to submit fitment data. You can also choose to send fitment data indirectly to Amazon through a 3rd party fitment data provider. Fitment data is submitted via .xml feeds in the ACES format and flows through a number of systems, the last of which matches fitment data to product data in Amazon's catalog. The tool, which sends data to Amazon, is called the Amazon Merchant Transport Utility (AMTU). This is the only tool through which Amazon receives fitment data and we do not edit this data once it is in our system. We can only delete fitment records.

It is important to understand that Amazon accepts fitment data from a number of sources. Therefore, do not expect that the fitment data you provide will necessarily be the only fitment data shown for a given product.

Amazon prefers to receive fitment data either directly from a manufacturer/brand owner or from a manufacturer/brand owner approved 3rd party data provider. Not all sellers who request to become a direct fitment data provider to Amazon will be accepted. This decision is at the discretion of the Amazon Automotive Part Finder team. In instances where fitment data is not available from either of the two aforementioned sources, then Amazon will consider sourcing fitment data from other entities.

If you would like to submit fitment data to Amazon, please review this page: Providing ACES Data to Amazon Automotive. This page provides further details about the following:

  • How Amazon uses fitment data and matches it to ASINs, the ACES data standard, and the anatomy of ACES files.
  • It also outlines the two options (direct and indirect) that you have for transmitting fitment.
  • If you decide to submit fitment data directly, this document outlines the steps you need to take to prepare fitment data, become a direct fitment data provider with Amazon, and submit the data through AMTU.
  • It also includes a list of 3rd party data provider options if you choose the indirect method.

Newly uploaded fitment data may take up to 1 week to match to products that already exist on Amazon. If you are uploading fitment data to match to newly created products on Amazon, it may take as long as 3 weeks for changes to reflect.

If you have followed all the instructions in the Providing ACES Data to Amazon Automotive file, waited the requisite amount of time, and still do not see fitment data on your ASINs, then navigate to Contact us in Seller Central and follow the steps mentioned below:

  • Open a case under Products and inventory. Enter the title of the case as 'Submitted Fitment Data Not Appearing'.
  • In the case, include your Amazon fitment data provider account name, the AAIA brand name for which you submitted fitment data, the date the data was submitted, and 1-3 example ASINs.

This information will be routed to the appropriate team to look into this issue.

Partslink/OEM Part Numbers

If you are selling collision parts, you can upload Partslink numbers or Original Equipment Manufacturer (OEM) part numbers as product attributes to your ASINs. Partslink is a universal parts numbering system for the identification of aftermarket collision replacement parts. If you add either of these number types to your ASINs, they will map to fitment data in our database and result in fitment data being added to your ASINs. Learn more about the Partslink numbering system at the following website: https://www.partslink.org/.

Instructions on how to upload or edit Partslink numbers and OEM part numbers are below:

A: Creating listings

To create a listing with a Partslink number, there are two options available:

  • Adding Multiple Listings
  • Adding Individual Listings

To create a listing with an OEM part number, there is one option available:

  • Adding Individual Listings

Adding multiple listings (only available to sellers with Professional selling plans)

  1. Go to Inventory File Templates for Specific Categories and search within the "File Templates" column for the "Automotive & Powersports (Parts & Accessories)" link.
  2. Click the link, download the file, and fill out the relevant details.
  3. For the Partslink number, go to the "Template" tab of the file, search for "partslink number "and enter the relevant number in the corresponding column.
  4. When your bulk inventory file is complete, upload it by going to the Add Products via Upload page (see this page for more details and a video guide).

Adding individual listings

Go to this page and search Amazon’s catalog to determine if your product already exists.

  • If your product appears after searching, click the "sell yours" button. Depending on how the original listing was created, the listing you match to may not have all of the information you feel is relevant, such as a Partslink number or OEM part number. See Editing Listings Individually under section B below for instructions on how to add this additional information.
  • If you cannot match your product to an existing listing, then create a new product listing:
    1. Search for your product catalog within the text box. If you cannot find the catalog, select "Automotive Category" from the All Product Categories section at the bottom. Continue navigating through the categorization until you are asked to "Select" the product category.
    2. Enter the relevant information pertaining to your product. Depending on the product type, the "partslink-number" or "OEM Equivalent Part Number" can be found in the Vital Info or the More Details tab. To navigate to the More Details tab, click Advanced View on the top right of the page. The "partslink-number" or "OEM Equivalent Part Number" are not relevant for all product categories and will not appear within all Automotive categories.

For a detailed demo on how to create listings one-by-one, please watch the first video here.

B. Making changes to an existing listing

To edit a listing with a Partslink number, there are two options available:

  • Editing Multiple Listings
  • Editing Individual Listings

To edit a listing with an OEM part number, there is one option available:

  • Editing Individual Listings

Editing multiple listings (only available to sellers with Professional selling plans)

  1. To make bulk edits to multiple listings, you can use the template referenced in the Adding Multiple Listings section above.
  2. When completing the template, fill out the relevant Partslink number. You are not required to fill out the entire template. Instead, you only need to populate SKU (column A) to reference the related product and then update only the columns that need correction. Select update in Column L to complete the process. Columns left blank will not impact the existing listing.

Editing listings individually

Follow the instructions here. Additionally, this video provides a step by step tutorial on how to edit individual listings.

Note: Depending on the product type, the "partslink-number" or "OEM Equivalent Part Number" can be found in the Vital Info or the More Details tab. To navigate to the More Details tab, click Advanced View on the top right of the page. The "partslink-number" or "OEM Equivalent Part Number" are not relevant for all product categories and will not appear within all Automotive categories.

If you see Partslink numbers or OEM part numbers on your collision ASIN detail pages, but fitment data is still not surfacing, navigate to Contact us in Seller Central and open a case. Enter the title of the case as "Partslink Number (or OEM Part Number) Fitment Data Issue". Include the ASIN(s) in question in the case.
