We’re a huge believer in democratising data, making vehicle and part categorisation available to everyone. The Partly platform is a collaborative and open cataloguing platform for vehicle parts.

Images, pricing, marketing descriptions, are controlled by the business that uploaded it. Each individual business can choose who this data is shared with.

OEM reference data is primarily researched, structured, and standardised by Partly data teams, and provided to all Partly users. The Partly community also regularly creates and updates OEM data. Reference data does not include diagrams, but includes cross make fitments, part types, cross-references, and supersessions. Businesses who interact with OEM and aftermarket data can use this “OEM Link” to automatically add fitment, interchanges, and part types that are compatible with their own website, eBay, and most other online channels.

Part types, categories, part attributes, and translations are largely community driven. New options are suggested, reviewed and merged into the standard on a weekly basis.

Partly data overview

UVDB (Universal Vehicle Database)

UVDB is the Partly vehicle standard containing 150,000 vehicle definitions. Vehicle definitions are detailed descriptions of a vehicle including make, model, body code/chassis number, etc.

The Partly Catalogue

The Partly Catalogue is an open parts catalogue containing over 55 million aftermarket, OES and OEM parts. Each catalogue part in GAPC contains a part number, part-type, position, cross-reference part numbers, attributes, brand, and links with UVDB vehicles.

GAPC links with UVDB to provide fitment/compatibility data

Partly has nearly 400 million fitments links between catalogue parts in GAPC and vehicle definitions in UVDB. This standard of linking is an accurate and practical approach for fitment data.

Where does the data come from?

Vehicle data

Vehicle data is independently researched and maintained by our internal data researchers. This ensures that vehicles represented in the database are up-to-date and specific to the car part of each supported region. This is supported by data partners around the world. Community-driven changes are also included, with the majority of vehicles released now moderated by the community via Partly moderators.

Parts data

Most data is based on Partly's internal OEM research, and large scale community-driven OEM research. The data for over 40 vehicle OEMs is standardised, normalised and included in the foundational OEM data.While this process is extremely labour intensive, the benefit is a common language for parts, fitment, and interchanges used across OEM and aftermarket parts.Individual businesses are able to add part information and link parts to vehicles. Each data submission is processed via our novel consensus algorithms which cross-check each edit against OEM foundation data.Aftermarket manufacturers and distributors have the option to cross-reference parts to the OEM equivalent for extremely quick and accurate fitment information.All data is standardised using the Partly Open Data Standard, by our internal data team with community assistance. This involves mapping all vehicle properties, all part groupings, all part attributes, and standardising to standard part types.

What data is shared?

Because the catalogue is based on accurate OEM-quality data, the central catalogue is shared by all Partly users. Cross-references can be suggested by anybody and viewed by the community.

However, there is data that is not shared across the community. The following data is controlled by the owner (but can be shared by at the owner's discretion):

• Images
• Retail prices
• Inventory/stock levels
• Titles/names
• Descriptions, marketing material
• Kits

Part fitment and attributes can be viewed by anyone, but only used by distributors. It cannot be copied or downloaded.

How do I use it?

The Partly data standard is designed to support the data flow from manufacturers to distributors and retailers as well as connect them with key online sales channels such as marketplaces and other areas of e-commerce. To access cross-references, fitments, or existing researched data you can use the following tools.

PartsPal - Parts Catalogue Management Software

PartsPal is cloud-based software used by auto parts sellers to centralise and manage their parts catalogue. This is used to sell on marketplaces as well as their own website with fitment.

Partly API - Fitment Data API

The Partly API is a modern and scalable solution for businesses in the parts industry to communicate and share data in a standardised data “language”.
