Overview

Amazon provides a structured framework for sellers looking to list automotive collision replacement parts on its marketplace. This reference covers the specific requirements around part identification, fitment data, product attributes, and listing compliance that sellers must follow when offering collision parts in the Automotive & Powersports category.

Key Points / What Sellers Need to Know

• UPC or CAPA number required — Every collision part listing must include either a Universal Product Code (UPC) or a CAPA certification number. Without one of these identifiers, sellers cannot create new listings or modify existing ones.
• PartsLink numbering is essential — Amazon uses the PartsLink universal parts numbering system to map collision parts to fitment data, enabling customers to verify whether a part fits their specific vehicle.
• Fitment data drives discoverability — PartsLink numbers connect your listings to Amazon's vehicle fitment database, allowing buyers to search by year, make, model, and other vehicle attributes to find compatible parts.
• Exterior parts have extra requirements — Certain exterior collision parts such as bumpers, body kits, door handles, and mirrors require additional attributes including body-part-exterior-finish, color, and colormap values.
• Optional attributes are strongly recommended — While some product data fields are optional, providing them improves search visibility and helps customers confirm they are purchasing the correct part for their vehicle.

How the PartsLink System Works

The PartsLink numbering system is an industry-standard identification framework specifically designed for aftermarket collision replacement parts. When sellers add PartsLink numbers to their ASINs, Amazon automatically maps those numbers to fitment data stored in its database. This mapping is what powers the vehicle compatibility search tools that customers use when shopping for collision parts. Sellers can learn more about the PartsLink system through the official PartsLink website, and Amazon provides tools within Seller Central for uploading and editing PartsLink numbers and associated fitment data.
